Abstract

PURPOSE:To easily find (in which CPU) an error arises at the time of resetting by automatically setting ADF/SADF according to the set condition of a set document. CONSTITUTION:When only one document is set at the automatic document feeding device (ADF), that is set as the SADF mode, which is not released until a fixed time is passed after copying is finished. Meanwhile, when plural documents are set at the time of setting the SADF mode, that is set as the ADF mode after releasing the SADF mode. Moreover, in the case of an interruption mode during a document is set at the ADF, the ADF is inhibited to use and it is controlled to be used by removing the document. Thus, the connecting condition of the system can be speedily detected and easily confirmed.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a copying machine system control method, and in particular to an ADF system control method.
The present invention relates to an 'A D F control method for a copying machine, in which the copying machine is controlled using a plurality of CPUs.

[Prior Art] In recent years, digital copying machines have been equipped with an automatic document feeder (
A method is adopted in which mechanisms such as ADF (ADF) and sorter are small, a plurality of CPUs are used to control them, and communication between these CPUs is performed by serial communication.

Note that since this type of copying machine is well known, no particular literature will be cited.

[Problems to be Solved by the Invention] In the conventional copying machine described above, when an error occurs during initialization, it is difficult to discover which CPU the error relates to.

If communication is started only by a hard reset, a communication error may occur due to the difference in reset time between each CPU.

The present invention solves the above problems, makes it easy to discover whether an error occurred in the CPU at the time of reset, and automatically controls the mode setting of the ADF according to the setting state of the document. An object of the present invention is to provide an ADF control method for a copying machine.

[Means for Solving the Problems] The above purpose is to perform a logical sum of a hard reset signal and a CPU ready signal, control the reset using this logical sum output (soft reset signal), and check the set state of the set original. This is achieved by automatically setting ADF/SADF according to the situation.

[Operation] Uses a soft reset signal to put all CPUs into suspended animation (
By turning off the port, you can minimize power consumption at night, and by using the program start signal, you can turn on only the parts you want to use (for example, turn on only the printer when receiving a fax at night). (print out, etc.).

Furthermore, by using this reset signal, the connection status of the system can be quickly detected, and the status can be easily confirmed.

Furthermore, since the operation mode is controlled depending on the state of the document set in the ADF, there is no need for an ADF/SADF mode changeover switch or the like.

[Example] Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a block diagram of the entire digital copying machine, and FIG. 2 is a plan view of a writing section in the digital copying machine.

First, the general configuration of a digital copying machine will be explained using FIG. 1. As shown in the figure, a digital copying machine consists of a copying machine main body (1) and an automatic document feeder [ADF CO (II)].
It consists of four units: a sorter (ITI), and a double-sided inversion unit (IV).

The copying machine main body (r) includes a scanner section, a writing section, a photoreceptor section, a developing section, a paper feeding section, and the like. Next, the configuration and operation of each of the above sections will be explained.

[Scanner Section] A first scanner that is equipped with a reflecting mirror 1, a light source 3, and a first mirror 2 and moves at a constant speed, and a first scanner that is equipped with a second mirror 4 and a third mirror 5 and that moves at a constant speed. and a second scanner that moves to follow the first scanner at a speed of . A document (not shown) on the contact glass 9 is optically scanned by the first scanner and the second scanner, and the reflected image is guided to the lens 7 via the color filter 6, and then onto the -dimensional solid-state image sensor 8. imaged.

A fluorescent lamp, a halogen lamp, or the like is used as the light source 3, and fluorescent lamps are generally used because of their stable wavelength and long life.

In this embodiment, the reflecting mirror 1 is attached to one light source 3, but two or more light sources 3 may be used. Since the solid-state image sensor 8 has a constant sampling clock, the fluorescent lamp will have an adverse effect on the image unless it is turned on at a higher frequency.

As the solid-state image sensor 8, a CCD is generally used. Since the image signal read by the solid-state image sensor 8 is an analog value, it is converted into analog/digital (A/D),
The image processing board 1o performs various image processing (binarization, gradation processing, scaling processing, editing, etc.) and converts the image into a digital signal as a collection of spots.

In order to obtain color image information, in this embodiment, a color filter 6 that transmits only necessary color information is removably disposed in the optical path guided from the original to the solid-state image sensor 8. The color filter 6 is moved in and out in accordance with the scanning of the original, and functions such as multiple transfer and double-sided copying are activated each time, so that a wide variety of copies can be made.

[Writing Unit] Image information after image processing is written on the photosensitive drum 40 in the form of a set of light points by raster scanning with laser light in the optical writing unit.

A He-Ne laser was used as a laser light source. The wavelength of this He-Ne laser is 633 nm,
It has been used because it matches well with the sensitivity of conventional copying machine photoreceptors, but it has problems such as the laser light source itself being very expensive and the fact that direct modulation cannot be performed, making the device complex. .

In recent years, due to the increased sensitivity of photoreceptors in the long wavelength range.

Semiconductor lasers, which are inexpensive and can be directly modulated, have come into use. This embodiment also uses this semiconductor laser.

FIG. 2 shows this writing section, in which a laser beam emitted from a semiconductor laser 20 is converted into a parallel beam by a collimator lens 21, and shaped into a uniform beam by an aperture 32. The shaped laser beam is compressed in the sub-scanning direction by the first cylinder lens 22 and enters the polygon mirror 24 .

This polygon mirror 24 has a precise polygonal shape, and is rotated in a constant direction at a constant speed by a polygon motor 25 (see FIG. 1). This rotational speed is determined by the rotational speed of the photosensitive drum 40, the writing density, and the number of surfaces of the polygon mirror 24.

The reflected light of the laser beam incident on the polygon mirror 24 is polarized by the rotation of the mirror 24. The polarized laser light sequentially enters fθ lenses 26a, 26b, and 26c. fθ lens 26a.

26b and 26c transmit scanning light with a constant angular velocity to the photoreceptor drum 4.
0, the photosensitive drum 40 is converted to scan at a constant speed.
The image is focused so that it becomes the minimum light point at the top.

It also has a surface tilt correction mechanism.

The laser beams that have passed through the fθ lenses 26a, 26b, and 26c are guided outside the image area by a synchronization detection mirror 29 to a synchronization detection sensor 30, and the image data is detected after a certain period of time after a synchronization signal that outputs a cue signal in the main scanning direction is output. is output for one line, and by repeating this process, one image is formed.

[Photoreceptor Section] A photoreceptor layer is formed on the circumferential surface of the photoreceptor drum 40. Organic photoconductor (OPC) is used as a photosensitive layer sensitive to semiconductor laser (wavelength 780 nm).

α-3i, 5e-Te, etc. are known, and in this example, the organic photoreceptor (○pc) is used.

In general, there are two types of laser writing: a negative/positive (N/P) process in which light is applied to the image area, and a positive/positive (P/P) process in which light is applied to the background area. Adopts N/P process.

The charger 41 is of a scorotron type having a grid on the photoreceptor side, and charges the surface of the photoreceptor drum 40 uniformly (-), and irradiates the image forming section with laser light to lower the potential of that portion. Then, the background portion of the surface of the photoreceptor drum 40 has a potential of -750 to -800 V, and the image portion has a potential of about 1,500 V, and an electrostatic latent image is formed on the surface of the photoreceptor drum 40. A bias voltage of -500 to -600V is applied to the developing roller in the developing devices 42a and 42b.

A (-) charged toner is attached to visualize the electrostatic latent image.

[Developing Section] The apparatus of this embodiment includes two developing devices, a main developing device 42a and a sub-developing device 42b. In the case of only black, the sub-developing device 42b and toner replenishing device 43b are removed. In this embodiment, which has two developing devices, the main developing device 4
By putting black toner into the toner replenishing device 43a paired with 2a and color toner into the toner replenishing device 43b paired with the sub-developing device 42b, the main pole of the developing device of the other color is Developing is performed selectively by changing the position.

This development is combined with the reading of color information by switching the color filter 6 of the scanner, the multiple transfer of the paper conveyance system, and the double-sided copying function to enable multifunctional color copying and color editing. For developing three or more colors, there are methods such as a method in which three or more developing devices are arranged around the photosensitive drum 40, a revolver type in which three or more developing devices are rotated and switched, and the like.

The images visualized by the developing devices 42a and 42b are transferred onto the paper surface that is synchronously fed to the photosensitive drum 4o by being charged (+) by a transfer charger 44 from the back side of the paper. The transferred paper is transferred to the transfer charger 44.
AC static electricity is removed by a separation charger 45 held integrally with the photoreceptor drum 40 and separated from the photoreceptor drum 40 .

The toner remaining on the photosensitive drum 40 without being transferred to the paper is
The cleaning blade 47 scrapes off the photosensitive drum 40 and collects it in an attached tank 48 . Furthermore, the potential pattern remaining on the photoreceptor drum 40 is erased by irradiating light with the discharge lamp 49.

A photosensor 50 is provided at a position immediately after development. The photosensor 50 consists of a pair of a light emitting element and a light receiving element, and detects the reflection density on the surface of the photoreceptor drum 40. This is determined by writing a certain pattern (for example, a pure black or halftone pattern) in the optical writing section at a position corresponding to the photosensor reading position, and then developing it and the reflectance of the pattern section and the photoconductor drum other than the pattern section. The density of the image is judged from the ratio of reflectance of 40, and if it is light, a toner replenishment signal is issued. Furthermore, it is also possible to detect an insufficient amount of toner remaining by utilizing the fact that the density does not increase even after replenishment.

[Paper feed section] In this embodiment, there are a plurality of cassettes 60a, 60b.

60c, the transferred paper is passed through a refeeding loop 72 to enable double-sided copying or refeeding.

When the start button is pressed after one cassette 60 is selected from among the plurality of cassettes 60a, 60b, 60c, the paper feed rollers 61 (61a, 61b, 61C) near the selected cassette 60 rotate. Then, the paper is rapidly fed until the leading edge hits the registration roller 62. Although the registration roller 62 is stopped at this time, it starts rotating in synchronization with the position of the image formed on the photoreceptor drum 40, and feeds the paper toward the circumferential surface of the photoreceptor drum 40.

Thereafter, the toner image is transferred to the paper in the transfer section, the paper is suction-conveyed in the separation conveyance section 63, and the transferred toner image is transferred onto the paper by a fixing roller consisting of a pair of heat roller 64 and pressure roller 65. to take root.

During normal copying, the paper transferred in this manner is guided by the switching claw 67 to the paper discharge port on the sorter (III) side.

On the other hand, during multiple copying, the paper passes through the lower paper refeed loop 72 without being changed in direction by the switching claws 68 and 69, and is guided to the registration rollers 62 again.

In the case of double-sided copying, there are two ways to do it: using only the copying machine main body (1) and using the duplex reversing unit (1).Here, we will explain the former case. The broken paper is further guided downward by a switching claw 68, and guided by the next switching claw 69 to the tray 7o further below the paper refeed loop 72. Then, by reversing the roller 71, the sheet is sent in the opposite direction again, and by switching the switching claw 69, the sheet is guided to the refeeding loop 72, and then fed to the registration rollers 62.

[Automatic document feeder (ADF II)] This ADF automatically guides the documents one by one onto the contact glass 9 and discharges them after copying.

The stack of documents placed on the document feed table 100 is aligned in the width direction of the documents by the side guides 101 . The placed originals are separated and fed one by one by paper feeding rollers 104, and conveyed to a predetermined position on contact glass 9 by rotation of conveyor belt 102, and positioned.

When the predetermined number of copies have been completed, the original is ejected to the ejection tray 103 by the rotation of the conveyor belt 102 again. Note that the document size can be detected by counting the position of the side guide 101 and the feeding time of the document.

[Sorter (■)] Sorters the copy paper ejected from the copying machine main body (1), for example, in page order, by page, or in preset bins 111.
This is a device that selectively feeds a to 111X. Motor 1
Copy paper fed by a plurality of rollers rotated by 10 is guided to a selected bin 111 by switching claws near the entrance of each bin 111.

[Double-sided reversing unit (■)] As mentioned above, the copying machine main body (1) can only make double-sided copies of each sheet, but by attaching this double-sided reversing unit (IV), it is possible to make double-sided copies at once. It is possible.

When making double-sided copies of a plurality of sheets at once, the sheets guided downward by the paper discharge roller 66 are sent to the double-sided reversing unit (TV) by the next switching claw 67. The paper that has entered the duplex reversing unit (IV) is stacked on a tray 123 by a paper discharge roller 120. At that time, the feed roller 121, side alignment guide 12
2 aligns the copy paper vertically and horizontally. Tray 123
The copy sheets stacked on top are re-fed by the re-feed roller 124 during back-side copying. At this time, the paper is guided directly to the paper refeed loop 72 by the switching claw 69 .

It is connected to the sorter unit via a serial interface, and the paper is conveyed and discharged into each bin at a predetermined timing based on signals from the sequence.

The fusing temperature, photosensor input, laser diode monitor input, and laser diode reference voltage are input to the analog input. The fixing temperature is controlled on and off by input from a thermistor in the fixing section so that the temperature of the fixing section remains constant. The photosensor input uses a phototransistor to input the photosensor pattern created at a predetermined timing, and by detecting the density of the pattern, controls the toner density by controlling the toner replenishment clutch on and off. There is.

An A/D converter and an analog input to the CPU are used as a mechanism to adjust the laser diode power to a constant level. This is controlled so that the monitor voltage when the laser diode is turned on matches a preset reference voltage (this voltage is set so that the laser diode outputs 3 mW).

Image control circuits perform masking, trimming, erasing,
Generates timing signals such as photosensor patterns,
It sends a video signal to a laser diode.

The gate array uses a laser beam scanner unit to synchronize the 2-bit parallel image signal sent from the scanner with the synchronization signal PMSYNC, and further converts it into a 1-bit serial signal synchronized with the image write signal RGATE. Output to image control circuit.

Next, operation-related control will be explained. The main CPU has multiple serial ports and a calendar IC.
control. In addition to the sequence control CPU, an operation section, a scanner, a facsimile, an interface unit, etc. are connected to the plurality of serial ports I.

The operation section has a display that displays the operator's key power and the state of the copying machine, and the key power information is serially transmitted to the main CPU, and the display is lit upon serial reception from the main CPU. The scanner serially transmits information related to image processing and image reading, and exchanges preset information contents with the fax and interface unit. Calendar IC remembers date and time and turns on the machine based on this information.

Off control is also possible.

9. Electric magnification circuit 461 and scanner drive motor 4
65. The lamp control circuit 458 turns on and off the exposure lamp 402 and controls the amount of light according to instructions from the scanner control circuit 460.

A rotary encoder 466 is connected to the moving shaft of the scanner drive motor 465, and a position sensor 462 detects the reference position of the sub-scanning movement mechanism.

The electric magnification circuit 461 performs electric magnification processing on the dithered image data and the binarized image data according to the main scanning side magnification data set by the scanner control circuit 460.

Timing control circuit 459 outputs each signal according to instructions from scanner control circuit 460. That is, when reading starts, the CCD image sensor 407 receives 1

For the image reproduction system control unit, pixel synchronization clock pulse CLK, main scanning synchronization pulse LSNC, main scanning valid period signal ■, GAT
Outputs E.

This pixel synchronization clock pulse CLK is almost the same signal as the shift clock pulse applied to the CCD image sensor 407. In addition, the main scanning synchronization pulse LSYNC is
This signal is almost the same as the main scanning synchronization signal PMSYNC output by the beam sensor of the image writing unit, but its output is prohibited when an image is not being read. The main scanning valid period signal LGATE is the output data DAT.
It becomes high level H at evening timing when A1 and DATA2 are considered to be valid data.

In this example, the CCD image sensor 407 outputs 4800 bits of valid data per line. Further, the output data DATA1 is data of each odd-numbered pixel, and the output data DATA2 is data of each even-numbered pixel.

When the scanner control circuit 460 receives an instruction to start reading from the printer control section, it turns on the exposure lamp 402, starts driving the scanner drive motor 465, controls the timing control circuit 459, and starts reading the CCD image sensor. Further, the sub-scan valid period signal FGATE is set to a high level H.

This signal FGATE is set to a high level H and becomes a low level L when the time required to scan the maximum reading length (in this example, the longitudinal dimension of A size) in the sub-scanning direction has elapsed.

5 checks are being performed.

Next, each of the above checks will be explained.

(i) Reset Check FIG. 7 is a block diagram of the power supply circuit. The copying machine to which the present invention is applied has two power switches (hereinafter referred to as Sw), and Swl is connected to sub-Sw ( SubSw) and 3w2 are called main Sw.

In the same figure, either SW1 or 3w2 is turned on.
(When turned on), AC power is supplied to the main unit. 3
w2 has an ACI for detecting whether this Sw is on or off.

AC2 is provided. The ACI and AC2 are constructed as shown in FIG. 8 in the power supply circuit. That is, when 3w2 is off, AC is supplied, the photocoupler is turned on, and the input to the CPU becomes Lo++. 3
When w2 is on, the photocoupler PHC is turned off and the input to the CPU becomes High (high level). This AC detection signal is input to the CPU shown in FIG. 8, that is, the main CPU.

The reset checker lag control operation will be explained with reference to the flowchart of FIG.

The reset check first checks whether the timer has elapsed for a certain period of time (1). This is 1! This is to ensure time for each system to complete the initial set when the source is 0n10ff. Next, the flag is checked in 3w2 (2). If the flag is OFF, 3w2 is in the OFF state, and in this case, it is checked whether 3w2 is turned on (3), (4).

If it turns on here, the flag turns on (5)
The system moves from the system reset state 603 to the program start state 604, which will be described later, and the system starts up. If the flag is on, 3w2 is on, and in this case it is checked whether 3w2 is turned off (6
). If it turns off here, the serial data currently being output is checked (7), and when all output is completed (8) to (10), it jumps to the initial set (602) and resets the system. in this case,
To clear RAM with initial set, 3w2
The flag is turned off, and since there is no transition from the system reset state to the program start state, a pseudo state is created in which the power is turned off.

Also, while 3w2 is on, the reset signal of each system is checked (11), (12). Any one
If one system is reset, the system jumps to the initial set after the reset is released, and all systems are initialized.

(ii) 5equence 5erial Check
k (sequence serial check) If there is a serial input from the sequence, check it here and turn on the flag corresponding to the input data. Each subroutine performs necessary flag processing and drops the flag.

If there is data that you want to output in sequence in each subroutine, turn on the flag corresponding to the data. This flag is checked, and if it is on, the data is output and the flag is turned off.

(iii) Operation 5erial Che
ck (operation serial check, (iv)
Scanner Serial Check (v) Fax Serial Check
l Check (Facsimile serial check)
This is also the same as (ii) above.

Each state shown in FIG. 6 will be explained below.

[Initial Set] Figure 10 is a flowchart of the initial set operation.
The initial settings are being made.

Although the external RAM has been backed up, all areas that do not need to be backed up are cleared here. The reason for providing a delay of 100m5x before issuing a break signal is to allow sufficient time for each system to be reset. After that, a break signal is sent to each system to notify that the main CPU has been reset.

This is always valid, for example, when only the main CPU is reset, and by detecting this break signal, each system can immediately know that the main CPU has been reset.

Sufficient time is provided for each system to detect the break output. Then the serial port.

Set initial data and move to system reset state.

The system reset state is a routine that checks each unit before starting the system.

FIG. 11 is an explanatory diagram of the flow of communication with each unit, and the main PCB 1101 includes a main CPU 1102 and a sequence CPU 1103, and the reset signal is common. Fax CP in PCB1104
Since there is U1105 and it is a separate port, it also has a reset function independently. This reset signal is active high. Similarly, operation PCB1106. There is also a CPU in each scan PCB 1107, and each has its own reset (both active high)
, these reset signals are all input to the main CPU 1102. The main CPU U1102 looks at this reset signal, determines the status of each CPU, and resets each CPU after resetting.
A soft reset signal is sent to U.

FIG. 12 is a configuration diagram of the reset circuit, and the reset output from the PCB of each unit is connected to the reset IC 1201.
The CPU reset signal generated from the CPU port is ORed with the signal generated from the CPU port. This is for each CP
Even if the main CPU sends a serial code immediately after a hard reset occurs to the U, each CPU is still in an initialized state and may not be able to receive the code. Therefore, if the port is initialized after reset and cannot receive data, the port is shut down to continue the reset state, and is released when reception becomes OK.

FIG. 13 is a timing chart of FIG. 12. Moreover, FIG. 14 is a flowchart thereof.

The purpose of this system reset is to issue a soft reset signal to each unit to initialize them. When the CPU of each unit receives the soft reset signal, it clears the RAM, clears the ports, etc., and returns the unit to its initial state. Here RES-OPE
Only in (1), a soft start signal is also sent (b) to start up the operation section. However, the all-lights-out mode is specified to make it appear to be the initial state. Also, RES-
In FAX (4), the presence or absence of the FAX PCB is detected by a reset signal issued from the PCB. In other words, if the main PCB and FAX PCB are not connected, the input to the main CPU will always be high, as can be seen from FIG. Other units have a similar reset signal format, and the reset signal is a signal for detecting the presence or absence of a unit. The conditions for moving from the system reset state to the program start are main SW (S w 2
) is the On flag. As explained in "Reset Check", this flag turns on 1 sec after the Swan. In other words, after the power is turned on, a hard reset of each system is checked for 1 second, and when the reset is completed, a soft reset code is sent.

Here, how to use 5w-1 and 5w-2 will be explained.

i) Single copy machine...5w-1 is always Off, 5
w-2 is used as the main Sw.

ii) Copy machine + Fax--8w-2 always on, 5W-
2 is used as a pseudo main Sw.

Faxes must be available 24 hours a day. 5w-2
When 5w-1 is turned on and 5w-1 is turned off, only the DC power is operated and supplied to the PCB. By doing so, the user can receive a FAX even when the main SW is Sw -2 and the OFF is set to 0n10ff. 5
When w-1 is on and 5w-2 is off, this system reset routine continues.

Also, in this state, if the fax is received and a print request signal is issued, the system can be started up (proceeding to the program start routine) and printed out (in this case, the system is started up, but
(You may start only the printer (sequence CPU))
After the printout is completed, the system reset routine is executed again to turn the system off.

By doing so, nighttime reception and printing can be performed very easily, and by supplying only DC power, it is possible to significantly reduce power consumption.

The program start state is a routine that issues a program start signal to start up each unit.

Figures 15(a) to (g) are flowcharts for starting the program, and =ERR-CHK checks whether each unit is connected.If the operation unit is not connected, it cannot be displayed. Therefore, it becomes RET. However, if connected, each unit's Ch
eck and if the ID code is not received,
A display will be displayed on the LCD of the operation unit and the screen will move to the EM screen. At this time, in the system reset routine, ``Since all displays were set to Off, display On is output to the operation unit.

The error display for each unit is as follows: Scanner S CN, No Connec
t sequence SEQ, No ConnectF
AX FAX No Conn
ect. As you can see from this flow, when there is an error on the operation panel, it cannot be displayed, so it becomes RET, and 5T
-8EQ, 5T-8CN, 5T-FAX, ate and other units are being launched. If the operation panel is OK and another unit has an error, the unit's error will be displayed on the operation panel and the EMMod will be turned off without starting up the other units.
Move to e. By doing this, when the operation unit is N0... 1) If other systems are starting up, there is a problem with the operation unit, 2) If other systems are not starting up, there is a problem with the entire system such as the power supply, etc. When the operation unit is OK...3) When an initial error occurs, such as a defect in the E error display area, the defective part can be found immediately.

In the 5T-8EQ, the program start code is sent to the sequence and the Acknowtalege (
If there is a signal (understood), it means that the sequence has started, clears the ST timer and ends.

5T-3CN is the same as 5T-3EQ, and 5T-FAX is the same as 5T-8EQ (only when connected to FAX).

CHK-ADF sends AD to the scanner when each unit finishes processing and the ST timer reaches 200m5ec or more.
I'm asking if there is an F. When a signal indicating that ADF is present is sent from the scanner, the ADF online flag is turned on.

5T-WAIT is when all units have finished processing and ST

Next, the WAIT mode (standby mode) will be explained.

WAIT mode is a standby state, in which communication with the operation unit, scanner, sequencer, and fax is performed, and mode (M

This will be explained with reference to the flowcharts shown in FIGS.

Note that FIG. 16 is an overall flowchart, and FIGS. 17 and subsequent figures are detailed flowcharts.

1. INIT-MAG (Fig. 17) Here, the variable magnification display on the LCD is initialized. When the independent display mode flag (Flag) is on: When the flag is off, the following is displayed. Here, the initial state is displayed with the flag turned off. LCD-MAG is the first
This is a routine that sends the magnification display displayed on the line to the operation panel.
LCD-DISP2 is a routine that sends the second line display to the operating section.

2. INIT-DISP (Fig. 18) This is a routine that displays the initial mode on the operation panel.The characters, the initial of one character/photo, and the presence or absence of AE at that time are displayed in SP-DISP.
The decision is made by looking at the contents of the RAM set in the mode.

4. INIT-REG (Figure 20) Sends data necessary for sequence and scanner control. First, register data is sent to the sequence.

This is the data set in SP-mode.
The registration adjustment amount in the main scanning direction, the registration amount in the sub-scanning direction, and the image writing width in the sub-scanning direction are sent to the third cassette. Next, fixing control data, toner control data, and the presence or absence of a 2-bin sorter are sent. Registration data to the scanner.

Send magnification data.

At the time of an interruption, the ADF original presence F1agJ is also turned off, so even during one interruption copy, the ADF can be used by removing the original and inserting the interruption original. Next, it is determined whether the mode is APS select mode or not, and if it is turned on, the APS LED is turned off.

6. LIFT-CHK (Fig. 22) When the ADF is lifted up,

8. SADF-RES (FIG. 24) Here is a routine for resetting the SADF mode when it is set. SADF mode is set by placing only one original on the ADF document table and starting copying (see 5ET-AD for details).
F). To reset the SADF mode, the timer is cleared at the end of copying, and this timer is set for a certain period of time (4 se
c) It is reset when the above period has elapsed. When set within 4 seconds, the copy start flag is turned on as shown by 0RG-CHK, the original is fed in, and the copy operation is started.

9. WT-TEN (Figure 25) This is a routine that checks the numeric keypad on the operation panel during Wait Mode. 1) Normal standby M) Manual feed standby 1ii) Independent magnification mode setting It can be divided into three parts.

i) Normal standby a) No-KEYIC Fig. 26) Here, inputs 1 to 7 on the numeric keypad are checked. First, if you have the key power, turn off the SP mode flag.
do. In this SP mode, when the keys are pressed in the order of ■, it enters a mode in which machine specifications can be changed in user mode, and when the keys are pressed in the order of ■, it enters a mode in which machine specifications can be changed. Enter the mode where you can change the machine specifications. The SP mode flag is a flag that checks whether these keys have been pressed in order, and if a key other than this key is pressed, the flag is turned off. Next, check 1-sided mode.

In duplex mode, check whether the back copy is on both sides. When the back copy is on standby, the key cannot be manually operated, so RET is required. This is because the displayed copies are already in the duplex tray, so if you set a new number that is less than this number, paper will remain in the tray when copying is finished, and if you set a larger number, there will be insufficient copies on the front side. In this case, the number of sheets cannot be set using the numeric keypad, and the number of sheets on the front side becomes the number on the back side. When the front side copy is on standby, key human power is only available when the number of copies is 0 or when the number of set sheets = the number of copies. In the above two cases, there is no paper in the duplex tray and a new front side copy is started; in other cases, the copy is interrupted, and by changing the set number of sheets, the front and back side copies are finished. , paper remains in the double-sided tray.

The number of sheets to be set cannot be set. However, if there are no copies in the duplex tray, there is no problem in changing the number of sheets to be set, so the setting is made. Also, if other numeric keys are being pressed at the same time or if the number of sheets to be set has already been entered, the keys cannot be pressed manually. The number of pieces set is 1 by the first key manual.
digit is set, and if the various Max displays are lit, the display is turned off, and the warning display (LCD) is also turned off. In the second input, set the 1 digit → 10 digit, and
Enter data in the digits. Next, if an upper limit has been set for the number of copies set in the SP mode, this is checked, and if the upper limit is exceeded, the number of copies set is changed and the Max display is turned on.

b) No-KEY2 (Fig. 27) Here, check the numeric keys 8 to 0, the C/S key, and the # key. Processing of keys 8 to 0 is No-KEYI
The C/S key # key will be explained.

When the # key is input, look at the SP mode flag, and if the mode clear 10 C/S flag is on, user mode, and if the mode clear 10/S 10 auto density is on, SP mode in serviceman mode. Move to. In other cases,
Turn off the flag.

At the OFF timing, the C/S key checks the SP mode flag and sets it to 0ff10n. At the ON timing, it first checks whether it is pressed at the same time as the preheating switch, and if it is pressed, sets the ID code OK flag to OFF.
ff. When copying by inputting the password mode, this flag is turned on when the password code is input, and when this flag is turned on, copying is OK. Therefore, if both keys are turned on, the flag will be turned off and copying will not be possible. If the C/S key is pressed during front copying in double-sided mode, it is assumed that front copying has been stopped midway, one-sided double-sided tool mode is set, and the number of front copies is set as the number of back copies. In the case of single-sided to double-sided, if there is a document, Feed 0ut (eject), and in the case of double-sided to double-sided,
Invert. If it is not double-sided, set the number of sheets by 1. Set the number of copies to O, erase if Max is displayed, and select AD
Turn off the F-return number LED. This is because when copying using the ADF, the copy jams and the number of returned copies is displayed.

This is to turn off this display. If the original is set in the ADF, Feed Out. The following is the same as in double-sided mode, clear SADF mode, and
When the MS and APS stop flags are on, the flags are turned off. This flag is set when size detection using AMS or APS is stopped due to size or other differences (SET-ADF).
- Also drops the Not Ready Flag. Normally, during APS, printing is OK even if there is no paper in the selected cassette, but if this flag is on, printing will not be possible. This flag turns on when copy operation starts (SET

Inputs other than the 0 key (8, 9) are processed in the same way as IN-KEYI, and if 0≠, it is valid only when the 1 and 10 digits are input. When the # key is pressed, processing in each mode is performed (see details for each magnification mode).

10. WT-KEY3 (Fig. 34) This is a routine that checks the key power on the operating section during Wait Mode, i) Preheat ■) Program ■) Interrupt iv) Print Sw V) Auto density vi ) There is a manual density.

i) Preheating (Fig. 35) Turn off the preheating flag at the off timing of Sw, and
The P mode flag is turned on. At the ON timing, when the flag is OFF, it is when Sw is pressed for the first time, the flag is turned ON, the preheating timer is cleared, and the AD
If there is a document in F, it is fed out, each ADF mode is reset, and the document is moved to WAIT. The mode is initialized here (mode clear key). If you continue to press the button further, when the timer reaches 1 sec or more, the preheat flag is turned on and the mode shifts to PRE HEAT mode.

ii) Program (Figure 36) When Sw is pressed, the SP mode flag is turned off and the LE
If D is on (already in program mode), turn off the LED, display the magnification on the LCD,
Move to WAITO. When the LED is off, the LCD is used in the program mode, so the independent variable magnification mode is cleared and the program mode is entered.

If you are already in interrupt mode, set the LED to 0ffL.

If the document is not in the interrupt mode and there is a document on the document table of the ADF, the paper presence flag is turned on at the time of 1 interrupt and the document is RET.

tv) Print Sw (Fig. 38) When Sw is pressed, the start flag is turned on and the sp mode flag is turned off.

(2) Automatic density (FIG. 39(a)) Check the SP mode flag at the Sw off timing. The automatic concentration flag is also turned on only when the preheater C/S is turned on. At the ON timing, edit mode (
Edit Mode) (outline and marker specification), keys are turned on when not in automatic separation mode. When in automatic density mode, if the manual density display is not displayed, set the density to 4 (center); if it is displayed, just turn off the automatic density display (
i). When automatic density Mode is Off, Manua
Turn off LED and turn on automatic density (fit
). This is shown in FIG. 136(a).

vi) Manual Density (Figure 40(a)) In Edit Mode, manual Sw is not marked. When the light switch is pressed, the SP mode flag is set to 0ffL and the automatic density switching flag is checked.

This flag is a flag to disable manual operation with automatic density, and the mode is the same as that of a conventional copying machine. This flag can be set in SP mode.

If this flag is on and the automatic concentration mode is set, the automatic concentration mode is set to 0ffL and manual concentration 4 (center) (iv) (however, the automatic separation mode is not performed). In cases other than the above, if the concentration display is Off, the automatic concentration level (v), On
If so, check this concentration level as CheckL (v
i) If the density is not 1 (lightest), turn the buzzer OnL and lower the density by one. This is shown in Figure 136 (
Shown in b).

Similarly, Koi Sw is processed.

11. WT-KEY4 (Fig. 41) This is a routine that checks the input of keys on the operation section during wait mode. J i) FAX ii) Fixed magnification ni) Continuous page copying iv) Double-sided ■) There is a sorter .

1) FAX (Figure 42) When the FAX is connected and a key is pressed, the SP mode flag is set to Ofl and the buzzer is turned on. Turn on the fax mode and set the user select flag.

Let it be n. At this time, if the document transported by the ADF is on the contact glass, it will be fed out. Then, the jam recovery LED is turned off. Pressure plate original flag is O
In the case of n, it is assumed that the document used in the copy mode remains, and a warning message is displayed. At this time, the use of FAX is not permitted. Next, P
Check if AD is set to FAX. P
If AD remains a copy, a warning message will be displayed. At this time, FA
X is allowed.

ii) Fixed magnification (FIG. 43) 81 equal magnification mode (FIG. 44) When Sw is turned on, the MAX and MIN displays displayed in independent two-dimensional magnification are turned off. At the same time, in the AMS mode, the AMS-T-- code is turned off, and when the APS size confirmation display is on, it is turned off.

If the mode is already in the same size mode, the buzzer will not be turned on, and the independent two-dimensional variable magnification mode will be cleared, and the variable size data (vertical/horizontal copy vertical/horizontal size) will be erased.

"100%" is displayed on the first line of the LCD.

b. Enlargement mode (Fig. 45) If the reduction SW is turned on at the same time, enlargement is not performed. Perform AMS and APS processing in the same way as normal magnification, and turn on the buzzer. The magnification is the same, reduced.

In the case of 400% vertical and horizontal independent zoom, set it to 115%, and otherwise set the magnification one level above the displayed fixed magnification. Furthermore, the independent one dimension scaling mode is cleared and the dimension scaling data is erased.

The 1st line of the LCD displays the magnification factor (for example, "11").
5%) is displayed.

C0 reduction mode (Figure 46) In this case, 1 magnification is 1x, enlargement, vertical, and horizontal are independent.

If the zoom is 25%, set it to 93%, and for other cases, set the magnification one level below the displayed fixed magnification (others are the same as enlargement).

ni) Continuous page copying (FIG. 47(a)) When Sw is turned on, the sp mode flag is turned off and the buzzer is turned on. Next, CLR-KEY 1 is called. This was explained with CLR-KEY, but the copy counter is set to 0, and if the Max display is on, it is erased. A
If there is a document in DF, feed it out and clear other modes below. Since duplex mode and page snapshot are not compatible, turn duplex mode off. ADF here
The mode is different depending on whether it is present or not. In other words, A
If you do not have a DF, you cannot perform continuous page copying from both sides to one side, so do not select this mode.

That is, each time a key is pressed, if an ADF is available, the operation shown in FIG. 136(a) is repeated.

Also, when entering double-page → single-sided mode, if APS mode is set, the flag will be turned on and the LED will turn off.
This flag is checked when the two-page spread→single-sided mode is turned off, and if it is on, the APSLED is turned on again. This is because when copying a double-page spread document, only horizontal size paper can be used, so the APS mode must be set to 0ffL (6C8I Z-CHK).

iv) Duplex (FIG. 48(a)) When the duplex key and the page continuous copying key are pressed, the page quick copying key is given priority. The rest is the same as page continuous copying, and the mode Select repeats the operation shown in FIG. 136Ce). Double-page spread → Both pages are double-page spreads →
The same processing is performed as for the piece.

■) Sorter (Figure 49 (a)) Set S P Mode Flag to 0ffL in Swoon
, When the copy counter key is set to O and the copy counter key is set to counter in duplex mode, the key is not pressed.

This means that when the sorter key is attached, CLK-KEY
This is because the number of copies is set to O in 1, so paper remains in the duplex tray. Mode S select is the first
36. Repeat the operation shown in FIG. 36(f). Also, M.

If there is paper in the sorter bin when ``de'' is selected, ````'' is displayed and copying is not possible.

12. WT-KEY5 (Fig. 50) This is a routine to check the key power during Wait Mode, and it checks 1) APS 5) AMS ■) Cassette iv) Original type v) PAD i) APS ( (FIG. 51) When Sw is turned on, the sp mode flag is turned off, and when other magnification changing keys (A P S , etc.) have been pressed, RET is performed. Also, in the case of double-sided poems and tables, the copy counter is O (before copying), the copy counter = set counter (at the end of copying), and when there is no paper in the double-sided tray under conditions other than the above (copying is stopped midway and 1 Sw is only added when the paper on both sides is removed). This is a double-sided sad poem,
The copy size has already been determined (there are only the sizes in the duplex tray), and the AP
This is because if you change the size of paper to be placed in the duplex tray in S, a paper of a different size will be placed in the duplex tray, which may result in jams or mismatched copies when printing on the back side.

When the Sw is received, the buzzer is turned on and the APS, AMS
Set the stop flag to ○ffL, and set the warning LED to 0ffL.
Already off when in APS mode, turn on mode when not in APS mode, turn off AMS display, turn off Max display, clear independent 2 dimension variable magnification mode to 100%
Set.

ii) AMS (Fig. 52) The operation to accept and attach Sw is the same, the difference is AMSO.
Check APS at n time and set a flag if it is on.

This flag is checked when AMS is off, and if the flag is on, APS mode is set again.

■) Cassette (Fig. 53) There are two types of cassette: one is double-sided, and the other is not. When the paper is not double-sided, when Sw is pressed, the next cassette is selected. When there is no paper, you can select a cassette in the same way as when not duplexing.Also, when it is front side and other than the above, select that cassette only if there is a cassette of the same size as the paper in the duplex tray. The reason for this is the same as that described for APS. When a cassette is attached to a receiver, the APS mode is set to Off.

iv) Original Type (Fig. 54) This is the Sw for selecting the type of original, and is selected in the order of →Text →Text/Photo →Photo. In each mode,
Depending on the mode specified in SP mode, specify automatic density or manual density (text/photos are fixed at automatic density).

v) PAD (Figure 55) If you switch PAD to Copy-') Fax, Fax
mode. The processing direction is the same as the WT-KEY4 FAX.

13. WT-ZOM (Figure 56) i) ZOOM (Figure 58) ZOOM KEY (Zoom key) Enlarge or reduce.

If the same size key is pressed, no counter will be added. Also, when the switch is turned on for the first time, AMS and APS processing is performed.
Clears the dimension scaling mode and also clears the dimension scaling data. 500 m5ec flag is OnL, magnification is 25%
Then the buzzer won't sound. When not in the independent variable magnification mode, the magnification is set to 11%, and if there is a fixed variable magnification corresponding to that magnification, the corresponding fixed variable magnification display is turned on. LCD
Display the magnification (for example, "91%") on the first line of the screen. There are three display methods in this case:

(i) is Z oom D when the magnification is not independent
This is a method of owning.

(n) is a method in which when the zoom key is pressed during independent magnification, the zoom is down based on the vertical direction, the independent magnification is reset, and normal magnification is performed.

(ui) is a method of zooming down based on the horizontal direction.

Although not shown in this flow, there is a method of zooming down simultaneously in the vertical and horizontal directions when changing the magnification independently.

This method sets the magnification using independent magnification and two-dimensional magnification,
This is very effective when you want to slightly change the magnification after copying. This zooming method (it) during independent magnification, (
ui), (tv) are DipS for user selection.
w, stored in memory backup, etc.

In addition, in the independent magnification setting mode, the independent magnification data is lowered, if it is set to 25% or less (
For independent magnification settings, the magnification data can be set using the numeric keypad and zoom key), set 25%, and if it is 400% or more, set 400%. The first zoom down is done at 500m5ec, and from the second time onwards, the buzzer is set to 0ffL.
, Zoom down at 200m5ec・1t) Zoos' + (Figure 57) This is Zo
This is basically the same idea as on+ (zoom).

14, W T -M A G (Fig. 59) This is a routine that is checked when any of the independent 1-dimensional magnification Sw is pressed, and at the same time when the same magnification, enlargement, reduction, and zoom are pressed. If it is set, the receiver will not be attached, and when changing the magnification independently, the vertical and horizontal ratios will be different, so APS will not be applied. If AP
If S is not released, the display will display the message "Pyrituni Ivy, Yoshiba, Arimasen" and will stop after detecting the size, which will be very inconvenient.

i) Independent side (Figure 60) Dimension scaling mode when Independent Horizontal is pressed.

Clear the dimension scaling data. If you are already in the independent horizontal magnification setting mode, check the magnification, and if the independent magnification data is greater than 400%, set 400% to 5etL, MAX.
Display, when smaller than 25%, 25% is 5etL, MIN
Turn on the display and set the independent magnification to horizontal magnification L/,
Vertical and horizontal display is performed on the 1st line of the LCD.

If so, set the independent magnification to the vertical magnification and then enter the independent horizontal magnification setting mode.

↓ If you are not in the independent horizontal magnification setting mode, set the mode, and it was previously in the independent horizontal magnification setting mode. (i) is when you enter the independent horizontal magnification setting mode from normal magnification (n) is (iii) is when the independent horizontal variable magnification setting mode is entered from the independent horizontal variable magnification setting mode.

In this way, in the independent magnification setting mode, magnifications are set in addition to the current vertical and horizontal magnifications. A work area is provided, and the magnification to be set is blinking. This is very easy to understand because the user can compare the current magnification with the magnification to be input, and the magnification data to be input is blinking.

In addition to inputting directly using the numeric keypad, you can also input using the zoom key.

It can be fine-tuned and is extremely easy to use.

The timing to set the work area's independent magnification data to vertical or horizontal magnification is: (i) When the same key is pressed (when data is set in the independent horizontal magnification setting mode and the independent horizontal magnification key is pressed again) (ii) When another independent scaling key is pressed (vertical data is set when data is set in the independent vertical scaling setting mode and the independent horizontal scaling key is pressed) (iii) # (Enter) When the key is pressed (iv) When the print Sw is pressed.

ii) Independent (Figure 62) I have the same idea as independence.

ui) Dimension scaling When the horizontal dimension of the original is pressed, the independent scaling mode is cleared.

If you are already in the original horizontal input mode, check whether the horizontal size of both the copied originals has been entered, and if so, calculate the horizontal magnification and set it, and check whether the vertical sizes of both the copy and the original have been entered manually. Check and if it is done manually, calculate and set the vertical magnification.

Then display the vertical and horizontal magnification on the 1st line of the LCD (
If the size of both the vertical and horizontal dimensions is not included, the magnification cannot be calculated, so the magnification before changing the dimensions is displayed.)

(i) is when size data is not input (it)
If the previously input size data remains
All data is displayed by pressing one key, making it very easy to understand. Also, if data has already been input, the data will flash, and if no data has been input, 111 will blink, so the user can clearly see which data is currently being input. In addition, the timing to erase this -1 scale size data is only when you press a scaling key other than dimension scaling, or when auto-resetting. For example, after inputting and copying each dimension, slightly change the dimension. If you want to change it, the size data remains, making it very easy to understand.

Also, the timing to calculate the vertical and horizontal magnification is (i
) When the same key is pressed (ii) When the # key is pressed (iii) When the print Sw is pressed.

Normally, when only the vertical dimension is entered, only the vertical dimension is input, and when only the horizontal dimension is entered, only the horizontal dimension is scaled, but in SP mode, only the vertical dimension is input, and the horizontal dimension is If both dimensions (original and copy) are not entered or only one is entered, the vertical magnification is also set to the horizontal magnification, and if the opposite is true, the horizontal magnification is also set to the vertical magnification.

15. WT-EDIT (Figure 72) When Sw is pressed, the buzzer sounds. If you are already in that mode, turn it off and EDIT
Set the density data saved when entering the mode. If it is not in the mode, turn it on, and when you enter the EDIT mode for the first time, save the density data before entering, and reset the optimum density in the EDIT mode (notch 3 for automatic density). If this is a marker specification,
This is to prevent marker marks from appearing on the copy.

If the mode entered after that is the overall mode, the flag is 0ffL if the marker designation was previously entered.If the mode entered is the marker designation, the flag is OFF if the global mode was previously entered.

This is because if you want to invert or cut out holes using a marker, you do not need to reverse the entire hole, and if you want to reverse the entire hole, you do not need to perform 2 inversions with the marker. .

16. DUP-CHK (Fig. 79) Here, the paper on the duplex tray in the duplex mode is checked. If there is no paper in the tray, set the "double-sided tray paper cloth flag" to 0fft, (this flag is turned on in DUP-8EL, and if it is on, the paper in the duplex tray is ejected as a blank sheet by turning the print switch on), then In the case of both sides back...
If the front side is set and the paper is pulled out during duplex copying, if the ADF is used, set the reverse side to 2 and eject the original. In the case of both and both, the r inversion flag is turned on.

This flag is checked by the 5ET-ADF, and when it is on, the original is reversed and copying is started.

(It turns On when paper of the desired size is not set when performing S). If it is On, if a cassette that matches the document size data from the scanner is set, Select that cassette and turn off the warning display on the LCD. Also, in the case of manual feed, the buzzer and manual feed display blink every 500 m5ec because paper cannot be fed unless the first cassette is set. The original information is also displayed on the LCD.

18.8UP-DISP (Figure 81) Displays when toner near end, toner over, oil end, toner end, or PS error occurs.

Among these, the toner end display is not displayed during copying, but
This is done only in AIT mode. This is because if the toner end indicator lights up during copying, the operator may open the front door, etc. to replenish toner even during copying, and at this time, a jam, etc. condition may occur. This problem can be avoided by changing the display to near end-end after copying is complete.

(If you set a mode that allows copying), turn on the key counter display when the mode is other than Fax mode. Next, the door display and LCD are turned on when the door is opened, and turned off when it is closed.

21. SUM-DISP...Printer serviceman call (Figure 84) SCN-DISP...Scanner serviceman call (Figure 86) VID-DISP...Video System serviceman call (Fig. 85) When this signal is received, the display and LCD are turned on and the counter that counts the number of serviceman calls is incremented.

22. P P - E N D (Figure 87) If there is no paper in the selected cassette, the paper from the single-sided tray will be fed to the double-sided poem, so it does not matter that there is no paper in the cassette. Therefore, the no-paper indicator is not turned on (for example, if the cassette is removed during double-sided copying and the no-paper indicator is turned on, the operator will think that there is no paper left).

For anything other than double-sided or reverse-sided, first check whether you are in APS mode. If it is not APS, the no paper display is lit. APS

(Not Ready Flag)". This flag is set after APS detects the document size.

The AMS stop flag turns on (if a cassette matching the original size is not set in APS), and also turns on when the copy stops at the paper end. It turns off when the desired cassette is found after the APS detects the document size, and when the APS and AMS stop flags are set to 0ffL. This rAps, No
If t Ready Flagj is OFF,
Even if there is no paper in the selected cassette, if there is paper in another cassette, the no paper display is set to 0fft and copying is possible. If it is turned on, the 5th paper will not be displayed and the LCD will be turned on. This is because in APS mode, even if there is no paper in the selected cassette, if there is paper that matches the original in another cassette, you must select it, so copying is OK at first.
It is said that However, if it is found that the desired cassette is not available after performing size detection, copying is impossible, and therefore copying is rejected. Also, even if copying ends at the paper end, copying is not possible because there is no paper in the necessary cassette.

23. SORT-MAX (Fig. 88) In the sort mode, if the set number > 10 sheets, the set number will be set to 10 and will be displayed; in the stack mode, if the set number > 40 sheets, the set number will be set to 40, is displayed. 10 sheets is the number of bins in the sorter, and 40 sheets is the number of sheets stored per bin.

24. DUP-MAX (Fig. 89) In duplex mode, if the number of sheets set is >50, the number of sheets set is 50, and the size that can be copied in continuous page copying is A4 size or less horizontal size. Therefore, if A4 or larger paper is selected, this will be displayed. 50 sheets is the number of sheets stored in the double-sided tray.

25. DUP-3IZ (Figure 90) This is a mode for checking the size that can be copied in double-sided mode. Due to the limitations of the jogger that aligns paper, the duplex tray cannot align paper sizes smaller than A5 vertically, so when you start copying, check the cassette size, and if a size smaller than A5 vertically is selected, a warning will be displayed and it will not be possible to copy. do. Furthermore, even if the cassette is replaced during copying and paper of a different size is inserted, a warning message, for example, will be displayed and copying will not be possible.

26. A warning message SI Z-CHK (Fig. 91) is displayed, and copying is prohibited. Also, if the vertical size is selected for paper smaller than A4, a warning message will be displayed and copying will not be possible.

27. B I N-CHK (Fig. 92) Here, the presence or absence of paper in the bin of the sorter is checked. If there is no paper in the bin, in stack mode the bin number is set to 1 and paper is loaded starting from bin 1. For example, if up to 6 Bins are stacked and you remove the paper from the bin halfway, the stack will start from Bin 1 again. This is to make effective use of empty bins.

Set o to O so that it enters from the 1st bottle.

2g, 5EQ-RDY (Fig. 93) This flag is set to 0n10ff by the ready signal from the sequence (CPU of the printer section).

29, 8 CN-RD Y (Fig. 94) This turns off the flag by the ready signal from the scanner, and if it is ready, if the rSCN start flag is turned on (if you start the scanner with SET-ADF) This flag is turned on), and the flag is turned off, assuming that the scanner has returned to its home position.

30. MAN-8EL (Figure 95) If there is a document in the ADF in the process when the manual feed door is opened, the Feed is set to 0utL and the number of returned sheets is set to 1. Also, if a document is placed on the document table, the
Even if you turn on the paper cloth flag and enter interrupt mode,
This document is designed to avoid Feed InL. 0 When the manual feed door is closed, 1 clears the manual feed mode, and if the interrupt flag is on, it remains in interrupt mode, and if it is off, it turns off the interrupt LED and returns to normal mode. It's starting to go back.

In other words, there are two ways to enter the manual feed mode: ■ Normal mode → Interrupt key on → Manual feed door open ■ Normal mode □ Manual feed door open. If this happens, close the door to enter interrupt mode again, and then turn on the engraving key to return to normal mode (■).

The other case is when you directly open the manual feed, in which case it goes into manual feed mode, and when you close it it returns to normal mode (■).

31. READY (Figure 96) There are three period states.

i) Print button - red, "Please wait" display On ■) Print button - Red, "Please wait" display Off ■) Print button - Blue, "Ready to copy" display 0n 1) In this state, the printer or Although the scanner is not ready, there is no abnormality and the scanner is waiting for a ready signal (for example, waiting for fusing to start up).

■) This is a state where there is some kind of abnormality and copying is impossible.

1ii) This is a state in which the ready signal has come from the state in i), the printer and scanner are both ready, and there are no abnormalities.

32, AUTO-RES (Figure 97) Auto Re

35, FUSE-CHK (Figure 100) P 5-CH
When the mode is set to check the fixing temperatures p and s in the KSP mode, this routine requests data from the sequence and displays it on the LCD when data is input.

36. FAX-REQ (Fig. 102) Here, processing is performed when there is a print request from the FAX CPU. When there is a request, it checks whether the sequence (printer) is ready. If it is not ready, it sends a Not Ready signal to the fax. If you are ready, rFaxRead
y Check FlagJ.

This flag turns on when the clear timer has elapsed for 30 seconds or more (the timer is operated by the operation unit or scanner).

It becomes 0 when serial data related to the operator's operation is transmitted from the sequence, and the flag also becomes OFF at this time). If this flag is off, a not ready message is sent. If it is On, it is assumed that the machine has not been operated for 30 seconds or more, and the fax printing operation begins. At this time, the document is fed out, and if there is a pressure plate document, this is displayed and a ready signal is sent to the fax machine. With this ready, the fax enters the print timing mode.

37, WT -I NT (Figure 103) Here,
This is a routine that moves to TBINT when the interrupt LED turns on during wait mode. When feeding manually, the manual feeding flag is set to OnL, and when not feeding manually, the interrupt flag is set to OnL.

Next, the Copy mode will be explained.

FIGS. 106 to 135 are flowcharts thereof.

Here, control is performed from when the print switch is pressed to when copying starts and ends.

In Figure 106, the 5ET-ADF determines whether it is ADF mode or pressure plate mode, and if it is ADF mode, it determines whether the original is set on the contact glass or not, and when detecting the size in pressure plate mode, it determines whether the paper that matches the size and the magnification are selected. Determine if it is set, and if OK, 5
Sequence controller (printer part) with ET-8EQ
5ET-3CN sends a control signal to the scanner section, 5T-3EQ issues a copy start signal, and paper feeding in the printer section begins.

Briefly explain the copying operationJ Each time paper is fed, a paper feed signal is received and checked by the CP-FED. Next, when the paper is set on the registration sensor, a write ready signal is sent (check with CP-RDY). In response to this signal, a scanner start signal is issued and scanning begins. When the scanner starts, an image leading edge signal (FGATE) is sent from the scanner to the printer.

The printer feeds out the paper set in the registration based on this FGATE (registration can be adjusted by changing the feeding timing here). If the printer section does not receive the FGATE signal within a certain period of time (35ec) after sending the write ready signal, it will issue a request signal (
CP-REQ). If FGATE still doesn't come (55ec), Video.

An error will occur. When FGATE is sent, the paper is sent out, and when the paper is ejected (single paper is ejected from the main unit, double-sided paper is ejected from the double-sided machine, and sorter paper is ejected from the sorter machine), a copy paper eject signal is sent. . When the printer starts copying, the conditions for stopping are a copy stop signal or an abnormal signal (jam, door open).

-8TP is checked, and in case of abnormality, CP-EM is checked.

This Copy mode is Wait mode, INT mode (

In the two modes of ``single-sided'', a reverse paper feed signal is sent to the ADF, and in other cases, normal paper feed is sent and the process moves to TBC0PY1. If rADF 5tart FlagJ is On, it checks whether the ADF original is set in the specified position, and if it is set, the first copy (I S
tCopy). In the case of 1st copying, it is checked whether there is any paper on the ADF document table, and if there is no paper, the mode is set to SADF mode, and if there is, the mode is set to ADF mode. In the case of ADF mode, check whether to enter sort mode with 5ORT-CHK. This is set in SP mode, and the number of sheets set is 2 to 10.
When the number of sheets is 10 (because it is a 10-bin sorter), it becomes sort mode.

However, when interrupt mode, sort or stack mode is already selected, or when the copy counter is not 0 (

In AMS-CHK, if the magnification that matches the cassette cannot be set: is displayed, the magnification is set so that the entire original can fit in the cassette size, and the process stops.

If there is a magnification that matches the cassette, check the direction of the JJK manuscript and the direction of the cassette (vertical and horizontal), and if they do not match: is displayed and stops. At this time, if the ADF is used, the document is ejected (Feed 0ut).

Even when the "rAMS/APS stop flag" is turned on to display a warning and the machine is stopped, the print switch remains green and is in a print ready state.

Then, copying starts when the next print switch is turned on.

If the "PS stop flag" is on, the process is set to 0ffL and starts (■). At this time, if the reversal flag is on, the original is reversed and then the process starts. If the ADF is not used and the original is a pressure plate original, the CADF counter = O), AD

and start. If the flag is OFF, the rMM detection flag is checked, and if it is OFF, it has not been checked yet, so the flag is turned ON to determine whether the mode is APS/AMS mode, and if the mode is OFF, copying starts. When the mode is on, the print switch is set to red and a code is sent to the scanner to detect the document size. When the size data is input from the scanner, APS-CHK,
AMS-CHK is performed, and if the stop flag is on, move to ■. At this time, if the original size cannot be detected, the "press plate original present" flag may be dropped to indicate that there is no pressure plate original.

When double copying APS/AMS, the original is vertical size,
I make it so that the copy starts only when the copy is horizontally oriented.

This is because the original is horizontal as shown in Figure 136 (C).
Copy vertical, original horizontal, copy horizontal, original vertical.

This is because blank space appears when copying vertically.

2.5ET-3EQ (Figure 111) Here, when starting copying, the sequence CPU
It sends data such as paper output slot, number of copies, etc.

In Figure 111.

a) In SEQ-IN, a paper feed port is selected according to each mode selected on the operation unit, and the selected paper feed port is sent to the sequence CPU.

b) SEQ-OUT (FIG. 112) selects a paper discharge outlet according to each mode selected on the operation unit and sends it to the sequence CPU.

c) SEQ NUM (Figure 113), first, the original counter (Original Counter
) is +1, and this counter is used for the number of originals returned for jam correction in CP-EM, etc.), and when the "double-sided paper cloth flag" is 01, 50 sheets are sent as the number of copies.

This is the maximum number of sheets stored in the duplex tray, and when this flag is on, there is paper in the duplex tray when the duplex mode is set, so the number of sheets in the tray at this time is unknown. Therefore, by sending the number of copies that can be stored in the duplex tray as the number of copies, all the sheets in the duplex tray can be ejected.a Original Counter+ 1
In the case of , the set number of sheets is sent because it is a case of copying again (starting copying the next original) during copy mode.

If Original Counter = 1, copy star 1 from Wait Mode
~ Therefore, first check the manual feed, and in manual feed mode, set the number of copies as rlJ, and set number of sheets ≠ number of copies (S
et #Copy), send rSet-Copy number.

d) SEQ-KEY (Fig. 114) is data sent to the key card, and is sent from the main CPU to the sequence CPU to the key card. Here, when inverting N/P, sending rs P 2J when photo mode is 1, sending rspl'' when editing markers or changing the magnification independently, and sending rNormal (
Normal)" is sent. This code allows the keycard to change the fare. In other words, until now, the price was changed depending on the size of the copy paper, but N/P inversion, photo mode, etc. use a large amount of toner, so the cost is higher than normal copying, and marker, independent, etc. This is because it is a special mode that other copying machines do not have, and because of this mode, the cost of the machine is high, so it is necessary to charge a high fee. This time, the modes are narrowed down and sent to the key counter, but by sending all the modes, the key card can set the fee for each mode.

In 3.5ET-8CN (Fig. 115), the mode inputted and determined from the operation unit is sent to the scanner, and the scanner scans according to this mode.

4.5T-8EQ (Figure 116), the sequence (
sends a copy start signal to the printer (printer) and saves the size data fed at this time.

This is used when performing limitless paper feeding when the paper runs out, or when preventing paper of a different size from being placed in the duplex tray.

5. The CP-FED (Fig. 117) checks the signal sent every time one paper is broadcast from the sequence, and when it is input, sets the copy counter to +1. however,"
If the "Double-Sided Tray Paper Cloth Flag" is on, the copy counter will not increase because the paper in the Duplex Tray is being forcibly ejected. If the PS data display mode is set, a data request signal is issued to the sequence here. In response to this signal, ps data is output. When this signal is input, data is displayed on the LCD using PS-CHK. Next, various counters are counted up. This count is counted up for each image in relation to the mode size, etc., and is stored in the backup RAM, allowing you to view the image in SP mode. Next, F
Check if ax is connected. If not connected, perform ID code check. this is,
In this mode, you can manually copy ID codes. In order to check how many sheets have been copied for each ID code, check the primary paper size that is counted up for each ID code, and select A3 size. In this case, turn on the solenoid to increment the A3 counter. Fax
is connected and in copy mode, only the ID code check is performed. In Fax mode, Fax
Close the counter and turn on the solenoid. In this way, the counter (hard counter) is used as an A3 counter when making a single copy, and is used as a Fax counter when sending a fax.

6. CP-RDY (FIG. 118) is a procedure when copy paper is fed, is detected by the registration sensor and stopped, and a printer write ready signal is sent from the sequence. When this signal is sent and the scanner returns to the home position, a scanner start signal is output to the scanner. At this time, density data is also output. Therefore, even if the density is changed during continuous copying, the next copy can be made at the set density. Next, specify the bin number of the sorter. Interrupt 2 When forcibly discharging the double-sided tray, outputs 0 to output to the interrupt bin. When double-sided, the paper is ejected to the double-sided tray, so no signal is output.In other cases, the sort mode outputs the bin number up. In this case, it is a 10-bin sorter, so if it goes up and becomes 11, it will be set to 1. In stack mode, the bin number is output as is, and in normal mode, 1 is output because it is 1 bin.

7. In CP-KEY2 (Fig. 120), when the clear stop key is pressed, the buzzer is turned on and the flag is turned off.
In this case, the flag is turned on and a stop signal is output to the sequence.

8. CP-KEY3 (Fig. 121) is a routine that checks the key during copying, and except for interrupt 1, it is the same as WAIT Mode, so interrupt-

nL, r copy start flag" is turned on. If there is no manuscript, set ``rADFyK draft flag'' to ○ffL,, ``
When interrupting, the ADF original document rough flag is set to 0ffL, and when in SADF mode, the "copy start flag" is turned off.

10. LIFT-CHKI (Fig. 124) checks for lift-up of the ADF during copying. When lifted up, in ADF and SADF modes, a copy stop signal is output in sequence. This is because if the operator lifts up the ADF during copying, it is the same as interrupting copying.

11. JAM-ADFI (Fig. 125) is a case where an ADF jam occurs during copying, and at this time, copying is immediately stopped.

12. In C3T-C:HK (Fig. 126), AD
Check whether the original sent in F is set in the specified position on the contact glass (signal sent from ADF → scanner), when set, ADF C
Set counter+ 1, set the flag that the document is on the contact glass, and set the rADF document stop flag to O.

13. In MAN-8E-Ll (Fig. 127), when the manual feed door is opened or closed during copying, it is basically the same as WAIT mode, but when it is opened, the copying A stop signal is immediately output to the printer to stop the printer's operation (the fed paper is ejected and then stopped).

14. KEY-COUI (FIG. 128) is a measure to be taken when the key counter is removed during copying. As soon as the key counter is removed, a copy stop signal is output and the printer operation is stopped. After stopping, move to WAIT mode and switch to KEY-CO
Press U to jump to TBWAIT and set to initial mode.

15. In FAX-NRDY (Fig. 129), when a print request comes from the fax machine during copying, the fax machine sends N
It returns ot Ready and puts it in a timed state.

It becomes OK when certain conditions are met in FAX-REQ in WAIT mode.

16. At CP-OUT (Figure 130), the paper ejection counter is incremented by the copy ejection signal (sent every time one sheet is ejected) from the sequence (printer),
When the number of sheets becomes the same as the set number, it is assumed that the copying of the original has been completed, and the original counter is set to 1.

17. CP-8TP (Fig. 131) is a process when a stop signal (when copying is stopped in a normal state) is sent from the sequence. When a stop signal is sent, a limitless check is performed first. Whether or not to make it limitless is set in SP mode.
Limitless is not performed when the conditions under which the copy stop signal is sent are other than paper end. When a copy stop is sent at the paper end, use 5T-3E.
Check whether there is paper of the same size as the paper feed size data saved at the start of copying in Q, and if the same size is available, select that cassette.

Next, the original counter is checked, and if it is 0, limitless is not performed. As written in CP-OUT, this is when the paper reaches the end when all copying of the original is completed.

At this time, the same size cassettes are selected.
This is because there is a very high possibility that the next manuscript will be of the same size. If the limitless flag is on, TBCO
Enters PY and starts copying 1 double-sided 2 page quick copy 1 manual feeding and normal copying 1. During normal copying, the first copy starts when the ADF starts.

No stop processing is performed. If the key counter is removed and the operation is stopped, the document in the ADF is ejected. If you press the clear/stop key to stop, the original will not be ejected if the toner end or paper end occurs. If the "copy ready check flag" checked by the CP-R8TR is On, it is assumed that the process has ended normally.

What is checking the "restart flag" here is
When the print switch is pressed at the same timing as the copy stop, the next copy has already started, so the copy routine does not end and is called RET. Check the paper end, and if it ends at the paper end, r A
Set P S Not ReadyFlagJ to On,
Check to see if there is an error mode on the 0th order that prevents the print button from turning blue. This abnormal mode is a serviceman call.

Others: ■Interrupt flag On, LED Off→Cancellation during interrupt, so go to TBINTφ. ■Interrupt flag On, LED On→Go to TBINTφ because interrupt is in progress. ■Interrupt Flag Off, LED On-'): Interrupt during Ibee. Go to TBVAITφ, 0 Interrupt Flag Off, LED 0ff4 Copying is in progress, so move to TBVAITφ.If you want to move to another mode at this time, eject the original in the ADF (■ and ■).Double-sided 2 The process of continuous page shooting and single manual feeding will be explained.

When the original counter≠0, the process moves to ■ and ends except when there is no paper in the duplex tray during double-sided back side copying. If there is no paper in the tray, set the front side, and when holding one side or both sides,
When in DF or SADF mode, if the blank paper ejection mode is set, the number of return sheets is set to 1, and in other cases, the original is ejected and returned, the number of sheets is set to 2, and the process moves to ■. For both sides, check the key counter if the ADF counter ≠ 0, and if it is, flip the original, check the toner end, paper end, and copy stop flags, and then OK.
If so, move to TBCOPY and start copying the missing amount.

When a single-page spread is displayed, it can be copied as is.

Check each stop condition and if OK, TBCO
Move to PY and start copying the missing amount. When the original counter is 20, when in 1 duplex mode, change the mode to the back side if the front side is taken, and the front side if the back side is 6 pieces.
When in ADF mode, check 0M for blank page mode.
If there is paper on the manuscript table, AD will start unless there is a stop condition.
Move to TBCOPY to make the next copy using F.

If not, and the "odd-number original document/date paper ejection mode" is set in the sp mode, the ADF and SADF modes are canceled, the blank paper mode flag is turned on, and copying is started.

When not in ADF or SADF mode or when blank paper is not ejected, return to the specified mode from ■, @l.
, Checking the toner end. In other words, as soon as the front side is finished, it will be reversed, prepared for the next copy, and then stopped.If the user lifts up the 80F, if the original is set as is (without being reversed) (If you stop at C/S, paper end, toner end, etc., you may have to reverse the copy, which can be confusing)
Since the back side copy is a copy of the rear part of the document, ADF processing is not performed.

In page continuous copying mode, one page spread, 9 and 9 sides, is basically the same as duplex mode, but the difference is that in page continuous copying mode, copying can also be done with an interrupt, so there are no interruptions during copying, and cancellation of interrupts during copying. The time is to eject the original from the ADF and then stop.

When copying with two pages on the screen, press ■ to check the number of sheets to return. When in ADF or SADF mode, check each stop condition. When OK, move to TBCOPY.

5ORT-CHK checks the number of copies per bin in sort mode, and if it is 50 or more, rBi
The n-over F lag J is stopped by turning ONL, and when 10 Bins are entered in the stack mode, the r-Bin over F lag J is turned on and stopped.

18. Manual feed for CP-R5TR (Fig. 134).

In order to increase productivity when printing other than double-sided 2-page continuous copying, the system judges whether to proceed to the next copy operation when the last copy is fed, rather than proceeding to the next copy when the last copy is ejected. There is.

First, check that the printer is ready and that the number of sheets set equals the number of copies. The number of copies is CP-
As mentioned in connection with the FED, since the count is increased when paper is fed, the check starts when the last paper is fed. Performs various checks, and when it is OK (Scanner Ready indicates that the scanner has returned to its home position), checks whether the printer button should turn green ("Copy Ready Ch").
eck FlagJ). Check the copy stop conditions here, and if OK, select "Copy Ready Check F".
Turn on lagJ to enable printing. Next, perform 5OR-CHK (same routine as CP-STP), feed the ADF original to 0utL, and correct the number of returned sheets. “Copy Ready Chek FlagJ is on
"Check copy start Flag J. If the flag is OFF here (if the print switch is not pressed or the next original is not inserted in SADF mode), check the ADF mode. Perform this check only once (rADF Start Ch.

“If copy start FlagJ is on, rlstcop
Set yFlagJ to On, and if there is no original on the document table of ADF, cancel SADF and ADF mode, and set rlstCo.
Set py FlagJ to 0ffL and move to TBCoPY.

19. CP-EM (Fig. 135) is a process when copying is stopped due to a jam, a serviceman call, etc. First, except for 1 manual feed 2 double-sided 2 page continuous shooting,
The paper discharge counter of CP-OUT is set as the number of copies. For example, this set copy display is paper and Ja+m (jam).
In the case of sort mode, this paper ejection counter becomes the bin number as it is, and the ADF-8AD
Check if it is F. When using an ADF and the original counter = 1, if the ADF counter = 0, the original to be copied has been ejected, so
If the number of sheets to be returned is set to 1 and ≠0, the document will not be ejected and the return will not be displayed (when copying is OK, just press Print Sv).

When the original counter≠1 (=2), the original counter is set to the number of returned sheets, and the ADF is ejected.

Next, check the stack mode, and if the number of sheets returned = 2, the stack bin number is next, so bin N
o-1 and ADF.

Clear SADF mode, clear each flag, TBZ
Move to M.

In manual feed mode, set the number of copies - 1 and then press TB.
Move to EM.

This is because when manually feeding, the number of sheets set is fixed at 1, but the number of copies is counted up so that you can see how many copies have been made when manually feeding.

For example, in the case of double-sided 2-page continuous copying, the process is the same as the others, but the difference is in the number of returned pages. No, this is 1 Usually, C
In order to increase the productivity of copying with the P-R5TR, by the time a copy of the original is ejected from the machine, the next original is fed and copied, so up to three types of copies can be stored in the machine. It will exist. - When a jam occurs, it is necessary to eject the fed original and start copying again from the previously ejected original. However, this process is not performed in page continuous copying 9 duplex. After the copy of the original is ejected, the original is replaced (see CP-3TP).

Therefore, there is no need to eject the original document during page continuous copying. When copying on the back side, if there is no paper left in the tray, the original on the back side will be ejected and the number of pages returned will be set to 2. When blank paper is being ejected, only the front side of the original that has already been ejected needs to be returned, so set this to 1).

Also, in both-simultaneous mode, since the next copy needs to be reversed to the front side, the "reversal flag" is turned on. This flag is checked by the 5ET-ADF, and if the flag is on, the document is reversed and started.

EM mode (abnormal mode) This mode is a routine that runs when the system becomes abnormal. WAIT C0PY.

This is a routine that operates in the event of any error such as INT, FAX, etc. Here, a stop signal is sent to the printer section, and the print SW can be copied in red and r.''The ``Please wait'' display is turned off, and the AD mode is reset to wait until the abnormal mode is released.

When the abnormal mode is released, it returns to its original Lunitin state.

Each of the processing routines will be explained below with reference to FIG. 137 and subsequent figures.

1. When the PRT-5TP (Fig. 138) enters the abnormal mode, it outputs a stop signal to the printer section (sequence).

2. N0T-RDY (Fig. 139) turns the print switch red and turns off both the "Ready to copy" and "Please wait" displays.

3. EM-ADF (Fig. 140) is SADF, ADF
Reset the Mode.

4. EM-KEY2 (FIG. 141) has a C/S key receiver in the abnormal mode, and the CLR-KEY, which has a receiver except when both sides are facing down, is in No-KEY2.

5. EM-WT (Fig. 142) is the destination when the abnormal mode is released, and is WAIT.

Return to INT, FAX.

Interrupt Mod
e) In (Figs. 143 and 144) interrupt mode,
When interrupt 6 or manual feed, which is a routine during manual feed mode, is set, the mode is saved at WT-INT and the process moves to TBINT.

Here, first, the display is initialized and the MAN-
Use CHK to check whether it is manual feed mode. If you are in manual feed mode, it will move to TBINTI. Interrupts can occur in the following cases:

■Wait Mode 4 - (Interrupt key 0n) (Interrupt key On) 9 Interrupt mode ← (Manual feed 0ff) (Manual feed On) → Manual feed mode ■Wait Mode (Wait Mode) ← --- (Manual feed 0ff) ( Manual feed On) Manual feed mode In other words, ■If you turn on the interrupt key from wait mode to enter interrupt mode, and then turn on manual feed to enter manual feed mode, even if you turn manual feed to 0ffL, it will not return to wait mode but return to interrupt mode. . Further pressing the interrupt key returns to wait mode.

■If you turn on manual feed from weight mode, you will enter manual feed mode directly, and if you turn manual feed off, you will return directly to weight mode.

Copying from an interrupt uses the same routine as copying from a wait in copy mode, and the same routine is used in EM mode even in the event of an error.

1. MAN-CHK Here, the 0 manual feed flag that checks the manual feed mode is turned on, and the AMS and APS modes are turned on.
ff and move to TBINTI. This is the routine for manual feeding.

2. With the INT-KEY3 (Fig. 145), programs cannot be called or registered during an interrupt, so the WT-KEY3
The program check routine has been removed from KEY3.

3. In INT-KEY4 (Fig. 146), when an interrupt occurs, it is not possible to switch to FAX mode, and the double-sided sorter is not used, so the FAX, double-sided, and sorter routines are removed from WT-KEY4. ing.

4. With INT-KEY5 (Fig. 147), it is not possible to switch to Fax mode during an interrupt, so WT-K
The PAD routine has been removed from EY5.

5. In INT-RES (Figure 149), at the time of interrupt,
When the print Sw is in the green state, if there is no change in the state for more than 1 minute, the document in the ADF is ejected, interrupts, and turns off the ED. Returns in mode.

6. In INT-MAN (Fig. 150), when the manual feed door is opened during 1 interrupt, the 1 manual feed LED lights up. At this time, turn on the flag, move to TB I NT, return the state to the initial state, and press MAN-CHK to start routine T for manual feeding.
Move to BINTI.

7. In INT-WT (Figure 151), 1 interrupt and ED
is off, set the interrupt 9 manual feed flag to ○ffL,
, set the saved mode and flag when entering the interrupt, and return to TBWAITO.

8. INT-CP (Figure 152) is exactly the same as WT-CP.

9. INT-EM (Figure 153) is exactly the same as WT-EM.

10. With MAN-KEY3 (Fig. 154), when inserting manually, the preheating 1 interrupt and program do not work, so the WT
- These routines have been removed from KEY3.

11. In MAN-KEY4 (Fig. 155), FAX, double-sided printing, sorting, and 'page continuous copying' cannot be performed during manual feeding, so these routines have been removed from WT-KEY4.

12. In MAN-KEY5 (FIG. 156), PAD, APS, AMS, and cassette cannot be used during manual feeding, so these routines are excluded from WT-KEY5.

13. At MAN-I NT (Fig. 157), check the LED of one manual feed, and if it is off, turn off the flag, move to TBINTO, and run the interrupt routine.

Interrupt Mode (Figure 158, 15
9) is a routine during the interrupt mode and manual feed mode. When interrupt or manual feed is set, WT
- Save the mode with INT and move to TB INT.

Here, the display is first initialized and 1MAN-C
Use HK to check whether it is manual feed mode. If you are in manual feed mode, it will move to TB I NT 1. Interrupts can occur in the following cases:

■Wait Mode ← (Interrupt key 0n) (Interrupt key 0) → Interrupt mode ← (Manual feed 0ff) (Manual feed On) → Manual feed mode ■Wait Mode (Wait Mode) ← -1 (Manual feed 0ff) (Manual feed On) Manual feed mode In other words, ■If you turn on the interrupt key from wait mode to enter interrupt mode, and then turn on manual feed and enter manual feed mode, even if you turn off manual feed, it does not return to wait mode but returns to 1 interrupt mode. return. Further pressing the interrupt key returns to wait mode. ■If you turn on manual feed from weight mode, you will enter manual feed mode directly, and if you turn manual feed off, you will return directly to weight mode.

Copy from interrupt uses the same routine as copy from wait in copy mode.

The same one is used in EM mode even in the event of an abnormality.

1. MAN-CHK checks manual feed mode. When the manual feed flag is on, AMS,
Set the APS mode to 0ffL and move to TB I NT l. This is the routine for manual feeding.

2. With INT-KEY3 (Figure 16'O), programs cannot be called or registered during an interrupt, so WT
- The program check routine has been removed from KEY3.

3. With INT-KEY4 (Fig. 161), when an interrupt occurs, it is not possible to switch to FAX mode, and neither duplex nor sorter is used, so FAX is not executed.

The double-sided and sorter routines have been removed from the WT-KEY4.

4. With INT-KEY5 (Fig. 162), when an interrupt occurs, it is not possible to switch to Fax mode, so 2 WT-K
PAD routine has been removed from EY5.

S, INT-RES (Fig. 164), at 1 interrupt,
When the print Sw is in the green state, if there is no change in the state for more than one minute, the document is ejected from the ADF and the interrupt LED is turned off. This causes the INT-WT routine to return in wait mode.

6. In INT-MAN (Fig. 165), when the manual feed door is opened during an interrupt, the manual feed LED lights up. At this time, move the flag to OnL, TBINT, return the state to the initial state, and enter the manual feed routine TB with 1MAN-CHK.
Move to INTl.

7. In INT-WT (Fig. 166), interrupt and ED
is off, the interrupt 2 manual feed flag is turned off,
When entering the interrupt, set the saved mode and flag and return to TBWAITφ.

8. INT-CP (Figure 167) is exactly the same as WT-CP.

9. INT-EM (Figure 168) is exactly the same as WT-EM.

10. With MAN-KEY3 (Fig. 169), when inserting manually, the preheating 9 interrupt and program do not work, so the WT
- These routines have been removed from KEY3.

11. In MAN-KEY4 (Fig. 170), FAX, double-sided printing, sorting, and continuous page copying cannot be performed during manual feeding, so these routines have been removed from WT-KEY4.

12. In MAN-KEY5 (Fig. 171), PAD, APS, AMP, and cassette cannot be loaded when one hand is loaded, so these routines are excluded from WT-KEY5.

13. At MAN-I NT (FIG. 172), the manual feed LED is checked, and if it is off, the flag is set Off, the process moves to TBINTφ, and the interrupt routine is run.

FAX-1:-Donitzite (Fig. 173), this Fax
What the main CPU does in this mode is
(Operation unit, scanner, sequence.

etc.) and the Fax CPU, and is the operation mode.

All basic operations such as scanner start and print start are performed using Fax CPU signals.

In the Fax mode, the main CPU performs (i) checking for ready conditions, (n) checking for the presence of ADF and pressure plate originals, (iii) displaying abnormalities, and (iv) checking for mode change.

1. In FAX-INT (Fig. 174), when entering the Fax mode, the key counter display is first turned off.

This is because the key counter is for counting copies, and sending a document by FAX or printing a received FAX has nothing to do with the presence or absence of a key counter.

2. With the ADF-3ET (Fig. 175), when the original is sent from the ADF and placed on the contact glass,
The [Original Stop Flag] is turned on.

3. In LIFT-CHKO (Fig. 176), each flag is dropped when the ADF is lifted up.

4. FWT-KEY4 (Fig. 177) is F'aX#
This is a check of the copy switching Sw. Print start, scanner does not start, ADF rFeed
If In FlagJ is Off, the mode can be changed (because no original is set), AD
If rFeed In FlagJ of F is on, check the [Original Stop Flag]. If it is on, the mode can be changed because the document is on the contact glass and the scanner has not started, that is, it has not entered the reading operation. If it is Off, the mode cannot be switched because FeedIn is in progress. FAX-3EL (1st
In Figure 79), if rFeed In FlagJ is on, FeedOutL is on, and if the pressure plate original flag is on, rADFNot Ready Flag is on.
A warning display will be displayed on the LCD. This is the same as Fax-9el in wait mode.

5. PAD-3EL This is a case where Faxφ copy switching is performed by PAD, and is the same as FWT-KEY4 (Fig. 177).

6. FAX-RDY (Fig. 180) performs a ready check in FAX mode. First, check the scanner's readiness. If the scanner is not ready, check the abnormal mode (serviceman call, etc.).
If there is no abnormality, turn on the print switch → "Please wait" in red and wait for the scanner to become ready. If there is an error, please wait" will not light up. If the scanner is ready, a sequence readiness check will be performed. If it is not ready, an error check will be performed. If there is an error, a print start signal will be issued, and the light will turn off. . scanner.

When the sequence is ready, it determines whether or not the fax is being processed, and if it is, it lights up. If it is not processing, it checks for an ADF jam. If it is not jammed, the print switch turns green. ” → Turn off the light.

In this way, even when the power is turned on, if only the scanner is turned on, the fax is OK. Normally, it takes 2 to 5 minutes for a printer to start fixing. However, in the case of sending by fax, since the printer section is not involved, it is determined that the document is OK as soon as the scanner starts up.

Also, although it is not explained here, if the user switches to fax mode, it is only for sending, so it may be OK even if the printer is not ready, or if there is a print request and the fax mode is switched. In this case, it may be OK even if the scanner is not ready.

7. PRT-CHK (Fig. 181) is a check for the print request signal sent from the Fax CPU when the reception of the Fax is completed, and when the sequence is ready, it transmits Ready to the Fax.

If the sequence is not ready, send NotR to the fax.
Send eady.

8. PRT-8TR (Figure 182) is PRT-CHK
When the fax receives a ready message, it sends a print start signal. When this signal is received, it sets the paper feed tray, paper output tray, etc., and sends a print start signal to the sequence.

9. FCP-RDY (Fig. 183) specifies bin N00 (interrupt) when a write ready signal (as soon as the paper stops at the register) is sent from the sequence, and sends an image start signal to the fax machine. The fax starts outputting an image signal from this signal.

10. When the FCP-8TP (Fig. 184) receives a stop signal, it turns off the start flag (S
One in T-3EQ).

11.8CN-CHK (Figure 185) is sent when the fax checks whether the scanner is ready before starting reading for transmission, and each Re
Send Ready, Not Ready.

12.8CN-8TR (Fig. 186) receives the scanner start signal from the fax, and then scans the density, scan data,
etc. and starts the scanner.

At this time, if rFeed In FlagJ is Off, it is assumed that the pressure plate original is "Press plate original FlagJ is turned on."

13. When the ADF-IN (Fig. 187) receives the FeedIn signal from the Fax, r Feed

Turn off gJ and send a Feed Out signal to the ADF.

15. When an abnormality such as a serviceman call, door oven, or jam occurs, the FWT-EM (Fig. 188) sets the preheating flag J to 0ffL, clears each flag, and moves to TBEM.For example, when a print request is issued from preheating mode, If an abnormality occurs while working in Fax mode, the preheating flag is set to 0ffL and the user's action is awaited.

16. FAX-RES (Fig. 189) is a routine that returns to copy mode if no operation is performed in fax mode for a certain period of time. First, if fax is in progress.

Clear the timer. This is useful when doing tasks such as photo manuscripts, which take a very long time to read and compress.
This is because the mode does not change.

If one minute or more passes without any action, clear each flag, turn off the user select mode, and enter TBWAIT.
Return to

17. FAX-WT (FIG. 190) is processing of a printout completion signal that is sent when printing by fax is completed (when all received data has been output) in the fax mode. When this signal comes, check the user select flag, and if it is on, R
It becomes ET. If it is off, the preheating flag is checked, and if it is on, it returns to TBHEAT, and if it is off, it returns to TBWAIT.

This occurs when there is a print request from a fax machine during wait mode or preheat mode, and the user is working in fax mode. When finished,
Each has returned to its original mode.

Regarding the preheating mode (Fig. 191), this mode is entered when the preheating key is pressed for more than 1 second in Wait Mode. Here, preheating mode LE
Only D is turned on, and all other displays are turned off. Fax
When there is a print request from , it changes to Fax mode, but when it ends, it returns to this mode again.

1. INIT-HE (Fig. 192) is the initial setting when entering the preheating mode. Sends preheating signal to ADF.

The ADF turns off all display-related functions using this signal. Next, a signal is sent to the sequence to lower the fixing temperature by 5°C from the current temperature. Next, turn off all the control lights and turn on only the preheating LED.
Let's do it.

2. HE-KEY3 (Fig. 193) is a check when the preheating key is pressed.

3. HE-FAX (Fig. 194)
This is the process when X finishes receiving and sends a print request. At this time, turn on the FAX mode and
Set the ADF to preheat Off, set the fixing temperature to normal temperature, and set the display on the operation panel to OnL to fax.
Move to mode. At this time, the preheating flag is ○ffL, so there is no preheating flag, so when printing is finished in the Fax mode, the machine returns to the preheating mode again.

4. In HE-WAIT (Fig. 195), if an abnormality occurs during preheating mode, the preheating mode is canceled and WA r
It moves to T mode, and then moves to FM mode by WT-EM.

About program mode (Fig. 196), 1. INI
In T-PRO (Figure 197), program mode,
First, it is displayed on the LCD. Next, [Input FlagJOn
When you enter the time using the numeric keypad, you can only enter 1 to 5.

When you press any other key, the message "Print Sw" → red is displayed, and the "Ready to copy" and "Please wait" messages disappear.

2. In PRO-END (Fig. 198), the # key is displayed, and To4 where 1 to 5 have been input flashes the input number at the above flashing position. Furthermore, if any of the numbers 1 to 5 are protected, the routine displays "1" and returns to the wait mode.

3. PRO-TEN (Fig. 199), a) Here, the program number is specified and set. If you do not press the O key from state 1, turn on the input F1agJ and press the # key, if it is protected, the C

Turn on J. This flag is checked at PRO-END.

b) If you press 0 from the state of 1, it becomes registration mode, but otherwise it becomes call mode. However, 6-9
is not set, so when you press the key In, it will be displayed. Even in the case of 1 to 5, if an unregistered item is called (for example, 5), it is displayed.

If registered, display the data and return to wait mode.

When registering the mode, register the number of set sheets → 1° and the number of copies → φ. The number of copies and sets are
There is no point in registering the displayed data as is,
This is because the next time you make a copy, you will most likely set a different number of copies.

4. PRO-KEY3 (Figure 200) is a check for the "preheat" and "program" keys in the program mode.

5. PRO-EM (Fig. 201) clears the mode when an abnormality occurs in the program mode and shifts to the EM mode.

Regarding the key counter password mode (FIG. 202), this mode is a mode in which copying is permitted by inputting a password instead of entering a key counter. This mode is set in SP mode 90, and the number of copies for each password code can be checked in SP mode 91. Since this mode is the same as the state without a key counter, it is possible to shift to the FAX mode.

1. INIT-ID (Fig. 203) is initialization of the key counter password mode, and first lights up the LED. The following is displayed on the LCD.

2. ID-KEYI (FIG. 204) performs a manual check of keys 1 to 7 in the code input check. The code is 4 digits, so have them enter it in order, shifting.

3. ID-KEY2 checks 8-0, clear key, and # key. 8-0 is the same as KEYI. When the clear key is pressed, all input data is set to 0fft.
,, you will have to enter it from the beginning.

Also, even when the # key is pressed, if 4 digits are not entered or if an incorrect ID code is entered, all input data is turned off. Correct ID code (there are 16)
is input, the key counter display is set to 0ffL, I.
Set the D code flag to One and move to WAIT mode. Returning from WAIT mode to ID-KEY mode is when ■AUT○-RESO has passed for more than 1 minute and the flag has turned off, ■C/S key and preheat key are pressed at the same time and the flag is turned off. In the two cases when
