Abstract

PURPOSE:To facilitate mode control and to make classification accurate by automatically selecting a sheet containing mode which is selected immediately before cutting off power source or a sheet containing mode which is decided beforehand when the power source is resupplied. CONSTITUTION:For example, when a sorting mode is selected, SSL=H is outputted from an outputting port P6 by a control program of muCOM in a mode storage control circuit 80, charging is started by C81 to turn on Q83, resulting that the output of Q84=L and SOM=L, and L is inputted to an inputting port F3. Because the before mentioned program is constituted so that SOM=L is judged to be a sorting mode, even when a sorter power source is cut off due to jamming or toner exhaustion, etc., if the capacity of C81 is made large, since Q82 is turned off during a specified time, Q83 and Q84 are maintained in an on-state. Therefore, when power source is resupplied, muCOM judges SOM=L to output SSL=H.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a paper sheet (hereinafter referred to as a sheet) such as copy paper or recording paper that is conveyed after being formed into an image by an image forming device of a copying machine, printing machine, or other recording equipment. It relates to a sheet distribution device (hereinafter referred to as a sorter) that distributes, stores, etc. Generally, a sorter has about 10 to 20 or more sheet storage stands (hereinafter referred to as trays or bins), and sheets that are continuously delivered from a device such as a copying machine at a certain interval are stored. , conveyance means using a belt, a plurality of roller means, or a combination of these conveyance means, etc., and the sheets are sequentially conveyed and stored in a predetermined tray.

When using such a sorter in combination with a copier,
There is a sort mode in which the sheets ejected from the copier are stored in trays in order and in a controlled manner and sorted, a non-sort mode in which all sheets are stored in a dedicated tray or a specific tray, and sheets of the same type are stored in the same tray. There are various usage modes such as collate mode.

In such cases, if a copying machine jams or runs out of toner, it is common for all sorters to be turned off during processing for sorters that receive power from the copying machine. . In such a case, if the sorter mode is in progress, the sequence mode after processing must be exactly the same as the sequence mode before processing.

The present invention provides a sheet dispensing device that allows convenient mode control for this purpose.

The copy sheet 3 is delivered to the inlet of the sorter 4 disposed opposite to it by the inlet guide 5 and a paper conveyance motor 28 (not shown).
It is guided to conveyance rollers 6m and 6b which are driven by b. The nib κ of the conveyor rollers 6a, 6b is disposed at the end near the sheet receiving opening of the tray 7.b Conveyor roller 96a,
The sheets conveyed from the tray 6b are stored and placed on the tray 7t. Incidentally, if it is possible to shorten the carry-in guide 5 further, the ejection rollers 2a and 2b of the copying machine 1 can be replaced with the conveyance roller 6.
a, 6 bt- This allows for more flexibility than using both a and 6 bt.

All of the tray details 7, except for the lowest tray 7', have both ends of the far end in the sheet conveyance direction placed in the engagement groove portions 8a of the tray swing support plate 8, and are operable in the sheet conveyance direction.

Also, the protruding member 7a at the proximal end on the sheet receiving opening side
It is supported by an arm member shown in FIG. 1 to be movable up and down along the long groove 9a of the b-arm support plate. Also, arm member l
9 is attached to the arm support plate 9 so as to be movable about its fulcrum.

Also, the lowermost traymer' is fixed to the tray swing support plate 8 and the tray support plate 9 with screws or spot welded (and also?', 8.9
It is also possible to integrate them. ) and has a structure that doubles as a cobby sheet storage tray and a frame structure that supports all tray groups.

FIG. 3 is a view of the sorter viewed from the K direction of the sectional view of FIG. The tray support plate 9 has a pair of protrusions 14a and 14b (see Fig. 3) crimped onto one end of the tray support plate 9 so that it can be engaged with the lead surfaces of the pair of lead cams 1ob and 1ob, and the tray support plate 9 can be engaged with the lead surfaces of the pair of lead cams 1ob and 14a, 14b (see Fig. 3). The sheet receiving opening of each tray can be moved up and down sequentially by the conveying roller 6.
It is possible to set it in a position opposite to a e 5 b.

That is, the tray support plate 9 can move up and down along the cam plate 10 in FIG. 2 at least by a distance corresponding to the distance from the tray 7 to the tray 7'.

The copy sheet 3 ejected from the ejection roller of the copying machine main body 1 is fed into the carry-in guide 5 on the sorter 4 side, and after passing the paper detection sensor 18, the leading edge is held by the conveyance rollers 6a, 6b). , tray 7,. At this time, after the rear end of the copy sheet 2 passes the paper detection sensor 1B and a sufficient time has elapsed for the copy sheet to be carried into the tray 7t, the bin moving motor 13 is activated. The pin moving motor 13 transmits drive to the lead cam lOb via the timing belt 22. Further, the lead surfaces of the lead cams 10a and 10b are partially horizontal and have a 1# hole. Further, on the lead cam surface, there are gears 15a, 15b to which the drive of the bin moving motor 13 is transmitted, and a sensor 20 for detecting one rotation per rotation.
A cam 50 having a structure in which a portion of the circumference protrudes in order to allow detection is integrally formed. Subpket 12a,
12b rotates in synchronization with the lead cam loa, 10b, and the pair of lead cams 10a, 10b rotates in synchronization with the chain 1.
1, it has a structure that can be rotated isotropically with lillii periods.

The lead cam 10b, driven by the bin moving motor l3 via the chain, rotates once and stops when the protrusion of the cam portion 25 is detected by the one-rotation detection sensor 20.

Further, arm members 19 are attached to the bottle support plate 9 so as to be rotatable at equal intervals on the front and back sides of the plate. This arm member 19#
i As mentioned above, the tip fins of the protrusion members 7a that are spot-welded to the ends of each tray at both ends near the copy sheet entrance of each tray are brought into contact with each other, and the far end of each tray in the sheet conveyance direction is swung. The tray group 7 is supported together with the tray swinging support plate 8 that is capable of supporting the tray group 7. Further, as mentioned above, the tray support plate 9 has projecting members 14a and 14b attached to both ends thereof so as to be able to engage with the lead surfaces of the lead cams loa and lob, so that when the lead cams log and 10b rotate once clockwise in the figure, the leads are removed. The tray support plate 9 rises along the surface by the lead distance, and stops after determining the position in the recessing direction on a substantially horizontal surface of a portion of the lead surface.

Next, to explain how to excite the bins of the sorter, initially, the tray details 7 are lowered to the bottom by rotation of the bin moving motor 13 in the clockwise direction shown in the drawing (the lead cam is rotated counterclockwise). , the sheet receiving opening is connected to the conveyor roller 6.
When the home position sensor 21 detects that the protrusion member 14a caulked to the tray support plate 9K corresponds to the position corresponding to the tap portion a, 6b, the bin moving motor l3 is stopped by the control circuit described later. The lower end of the tray support plate 9 comes into contact with a part of the sorter bottom plate (not shown) and is kept at a certain lowermost position. Next, copy sheet 3 is placed in tray 7.
When the paper detection sensor l8 detects that the copy sheet has been carried into the copy sheet and stored in the B tray 7-fold by the conveyance rollers 6a and 6b, the bin moving motor l3 is turned counterclockwise as shown in the figure after a certain period of time after detecting the trailing edge of the copy sheet. direction (lead cam clockwise), the lead cam that receives the drive rotates once clockwise,
It is positioned and stopped on the aforementioned predetermined horizontal plane.

Hereinafter, the above procedure is repeated, and after the copy sheet 3 loading section is repeated a predetermined number of times while always keeping the one-stroke interval, the tray 7 is placed in the uppermost position. When the upper limit detection sensor z3 is detected by the protruding member 14Jl caulked to the tray support plate 9 at the time when the upper limit is reached (position B in FIG. 3), the b-bin moving motor 13 is stopped by the control circuit described later. After that, even if the covey sheet 3 is carried in, the bin will not be moved.

26a and 26b in FIG. 13 are spring members applied to the shafts 10'a and IO"b that support the lead cam. For example, even after the tray details 7 reaches the lowest position (home position 1) or the highest position, If the home position sensor 2l or upper limit detection sensor 23 is not detected due to some defect, the motor continues to rotate in the same direction, and both protruding members 14a and 14b of the arm support plate 9 that engage with the lead cam loa e lOb are There is a possibility that a force exceeding the allowable shear stress will be applied, resulting in loss.

Even if such a phenomenon occurs, the spring members 26a and 26b as described above are connected to the shaft 10'Jl that supports the lead cam.
, lOIb, and if the lead cam is normally held down at 1M, even after the - rotation of the bin moving motor 13 reaches the home position 1 or the top position of the tray group 7, it may continue due to some malfunction. Even if the tray details 7 are positioned in the home position, the lead cam shaft 10
Spring member 26 upward along 'a, 1o'b!
, 26b are raised and lowered while contracting, thereby preventing damage to both the protruding members 14g and 14b of the arm support plate 9.

Next, the functions of the arm members will be explained in detail. Arm member 1
9 is screwed to the aforementioned sorter side plate 16 so that it can be positioned.
When the cam part 17Jlκ of the cam plate 17 comes into contact with the cam plate 17, one end of the arm plate rotates downward about the fulcrum of the A-man plate.
1 Upper tray 7. By the principle of a lever, the protruding member 7a on the tray side is raised along the long groove of the bottle support plate 9, and the tray 11 is moved so that the sheet receiving opening of the lower tray 7 is opened.

At this time, the tray 71 #i moves in the sheet conveyance direction, but since it is movably supported by the tray swing support plate 8 in the sheet conveyance direction, the displacement in the sheet conveyance direction due to a change in the inclination angle of the tray 7 is accommodated. be done. Also, at this time, the tray is at the fulcrum 8
Even if it rotates around the passage b, the proximal end face on the tray entrance side and 2
The book transport rollers 5a and 6b are positioned according to the specifications of the cam plate 17 and the arm member 19 so that the distance between the nip portions does not change. The positioning of the arm member l9 when the tray is not pushed up is done using the tray support plate 9.
This is made possible by the projection member 27 that is positioned and caulked.

FIG. 6 shows that the mode storage control circuit 80 stores the mode before the power was turned off even if the sorter power is supplied from the copying machine main body and the sorter power is turned off, such as when clearing a jam in the copying machine main body.

Even if the power to the sorter is turned off at t4, the C81 is set so that the discharge time of the C81 is approximately 10 to 20 minutes. If you increase the capacity of C82 when starting up the m source of the next sorter,

7 to 15 are program charts of an embodiment of the present invention.

Figure JI7 is a general flowchart showing the main routine. First, after the power is turned on, an INITIAL SET subroutine for setting the initial mode of the device is executed in Step 00. When the execution of Step OO is finished, the next Step
The process advances to ep 200, and after this step, a loop is drawn as main loop processing.

Step 200 is a routine to judge the status of the device, and it constantly monitors whether the JNT signal is detected normally or not while the sorter is operating, that is, whether the sorter is set in the ejection section of the copying machine main body. Watch, (JNT)
If (JNT) is not detected, it is determined that the sect has not been performed normally and the JANRESET subroutine is executed to execute the alarm operation.On the other hand, if (JNT) is detected, the device further executes the JANRESET subroutine.
It is designed to determine whether or not the M state is reached, and to execute the above-mentioned JAM RESET subroutine in the event of a jam.

If the state of the device is now normal, proceed to the next step 300. This is a KEYCHEC input to determine whether the sorter mode has been selected by the operator (KEY).
This is the KSLIB routine.

After execution, the routine Step 400 executes the operation according to the mode selected by the sorter in Step 300 described above.
, proceed to Step 500 and Step 600.

In this case, bMCO depends on the selected mode as described below.
The mode kakunta (

If the system enters the waiting state during the above-mentioned SUB routine, the system returns to the main routine and executes the next step 700. Self-diagnosis SL to self-diagnose
Execute iB routine.

Then, in Step 800, 1 is added to the contents of the timer, which will be described later.
Add and return to the main loop. After returning to the main routine from each SUB routine mentioned above, the SLI
When executing BILf-Ten, it is configured to execute from immediately before the previous standby state.

The individual subroutines will be explained in detail below.

FIG. 8 shows the INITIAL SE'l' supply which performs processing when the low power source is turned on.

In Step 101, it is checked whether or not the input signals (SOM) and (COM) from the above-mentioned mode selection system # circuit are detected.

If (SOM) is detected, it is determined that sword mode has been selected, (STLD) is turned on, the operator is informed of the selection of sword mode, and a predetermined area of shame in MCOM is set, which is used for mode setting described later. Assign 1 to the counter (MDCN) and turn on (SSL)O Similarly, if (COM) is detected, it is determined that collate mode is 1, and (NSTLD) is turned on (MDCN) = 2 [CSL
) on.

If both are not detected, it is determined that it is non-sort mode (N
STLD) ON (MDCN) = o.

This Step 101 makes it possible to return to the mode before the power off of the scissor.

Next, in Step 102, by checking whether or not paper is detected in (PAP), it is possible to prevent the sorter from operating in 11 when a cobby sheet is jammed inside the sorter when wm is on, and to notify the operator of paper jam tb. J, which will be described later
H eyes {ESET subroutine hairatr.

If there is no detection, the process returns to the main routine at RE1'.

FIG. 9 is a routine for executing mode selection switching processing at the time of (KEY) input by operator K.

First, in Step 301, the input of the (KEY) signal is constantly monitored, and if there is a (KEY) input, the process proceeds to Step 302, and if not, the process proceeds to Step 304.

Step 302 is a step (KE
Y) Each time there is an input, the mode display cycles in the order of non-sort → number → collate → non-sort. For example, when non-sort is selected, that is, when (NSTLD) is lit, (KEY
), the display switches to (STLD) lighting), the above-mentioned (SSL) is output, and the sort mode is selected.

However, at the time of mode switching by the (KEY) input, the contents of the mode counter (MDCN), which specifies the routine that executes the mode operation described above, do not immediately switch to the value corresponding to the selected mode, but temporarily change (MDCN). A value of 1 divided by a predetermined value is assigned to (MDCNSUB), which is the buffer 7, and a mode switching command is set to notify that a mode switching has occurred.

That is, when the operator switches the mode by inputting the (KEY), the display is switched in accordance with the selection, but the mode operation is K, which prohibits immediate switching.

Therefore, Step 304 is a step in which the above-mentioned mode operation switching is executed when the operator turns off the (KEY). If the mode switching command described above is set, the command is reset (MDCN) and (
MDCNSUB) is substituted to select a routine that executes the mode operation, and the process returns to the main routine.

In particular, when switching to collate mode by (KEY) input as Step 303, set the f{P return command to return the bin to the (HP) position.
This is to ensure that when the operator selects the collate mode, the bin must be returned to the home position before the sorter can be started.

Next, FIGS. 10 to 12 are detailed flowcharts of the SLIB routine that executes operations in three modes.) FIG.
This is a 7-row chart showing the B routine.

First, FIG. 10 shows a subroutine for executing the non-sort mode operation corresponding to the non-sort mode SUB 7l&/chin.

In the non-sort mode, the copying bin is returned to the home position in response to the (BCR) signal output when the copying machine starts copying, and all ejected copy sheets are stored in the first bin. As a detailed explanation, first, in Step 401, a [recovery timer] is started and a predetermined time is counted.
Step 402 while waiting for r(7) to finish, Step
Execute 403.

3iep 402 continues to monitor the input of the (BCR) signal, which is the start signal for the sorter, from the copying machine, and when it is input, it performs the HPRETSυB routine shown in Step 803 in Figure Kg13 to return the bin to its home position. The bin moving motor is rotated in reverse until the (HP) signal is detected, the bin is returned, and the motor is stopped when the (HP) signal is detected. It outputs a notification (SSTBY) signal, turns on the paper conveyance motor that conveys the floppy sheet, and returns to the state of waiting for the end of the [return timer].

In Step 403, (PAP) continues to monitor the detection of the leading edge of the copy sheet being ejected from the copying machine, and when it is detected, the above-mentioned (SSTBY) signal is sent to O7L, which monitors until the copy sheet is properly stored in the bin. In order to
Execute the ERCl-IEcK SLIB routine.

In Step 801, the copy sheet is successfully created (PAP)
The jamming jam timer is started to monitor the copy sheet passing through, and it continues to monitor until the timer ends (PAP) detects the trailing edge of the copy sheet, but if the trailing edge is not detected and the timer ends, it is recognized as a jamming jam. In order to notify the operator of the abnormality, the process advances to the JAM RESETSUB routine, which will be described later.

If it is normal, proceed to Step 802, start the ejection timer, which is an interval timer in the casing that stores the (PAP) in the bin after the rear end of the cobby sheet has come out, and wait for the timer to end, as the paper ejection is completed. The system is again in a state of waiting for the completion of the above-mentioned [return tie length].

When the return timer ends in Step 401 mentioned above, Step
Turn off the [paper transport motor] that is on at 402, and turn it off again at St.
In ep403, the (SSTBY) signal which is currently off is turned on to return to the initial state.

Now, when the copying machine outputs copy start on (BCR) and the sorter returns the bin to the specified position, the sorter returns (SSTBY) with 1 and waits for the copy operation to start. b1 and the time from the start of the copy operation until the copy sheet is ejected varies depending on the timing of the copy start. If the copy start is turned on after a predetermined period of time has elapsed since the end of the previous copy operation, the ejection of the copy sheet may be delayed.

At this time, by setting the length of the above-mentioned [recovery timer] to be equal to or greater than the above-mentioned predetermined time, the copier will immediately start copying since (SSTBY) is already on when the copy start is turned on. On the other hand, the sorter inputs the (BCR) signal and starts the operation of returning the bin to the home position, but the copy sheet is ejected with a delay after the first pin reaches the predetermined position, and it does not work properly. The copy speed increases by the amount of time it takes for the bin to return (as the time required for the bin to return) is increased, but if the time for cobby sheet ejection 1 is faster than the time it takes to return the bin, the recovery timer may also be activated. It is not finished and (SSTBY) is off. ! }), When the bin returns to the home position in (BCR), by turning on (SSTBY), you can wait until then for the copy operation to start, and the copy sheet will be placed normally in the specified bin. It will be stored.

Furthermore, even if the copying machine cannot eject a copy sheet due to a jam or a stop key being turned on, the copying machine can be returned to its initial state by expiring the [return timer].

Next, the 11th run is the count mode SUB routine, which is a subroutine that executes the sort mode operation.

In the sort mode, the (BCR) signal output when the copying machine starts copying returns the bin to its home position, stores the ejected coby sheets one by one in the bin, and stores the coby sheets that exceed the number of bins. If there is a sheet, it is stored in the topmost bin.

As a detailed explanation of this SUB routine, Step 50
1. The operation of Step 502 is the same as the above-mentioned Step 502.
401 and Step 402, details are omitted, but Step
Regarding p 503, (PAP) detects the leading edge of the copy sheet ejected from the copier and (SSTBY)
Turn off the l signal and turn off the 13th DXJ (7) The above-mentioned PAP
Execute ER CHECK SUB #-f 7.
Monitor the normal ejection of copy sheets and complete the 13th copy sheet ejection.
Execute SFT SUB v-chin shown in Step 804 in the figure.

In Step 804, a (UL) signal is detected to determine whether the bin is at the upper limit, and if so, shifting of the bin is prohibited.

If not, rotate the bin moving motor forward (REU) until the signal is 1.
Wait in the cabinet that detects the rotation, and if the rotation is detected, the bin movement motor is stopped as one bin shift is completed, and Step 5
Return to Step 03 b1 and return to Step 501 again.

Even in the sort mode, the above-mentioned [return timer] function is operated.

Further, the signals (BCR) and (SSTBY) for timing synchronization between the copying machine main body and the sorter have a similar structure.

Next, FIG. 12 shows a subroutine for executing collate mode operation in collate mode S[JB A/-chin.

In the collate mode, the binger is shifted by one bin according to the (BCR) signal output at the copy start time of the copying machine, and all copy sheets ejected by the copy operation are stored in a predetermined bin. The bins are shifted each time the bin is changed.

As a detailed explanation of this SUB routine, Step 60
1. In Step 6o2, the system continues to monitor the input of the (BCR) signal, which is a start signal for the sorter in the copying machine, and when it is input, the following two operations are performed.

That is, in Step 303 of FIG. 9 described above, [K
EY) When switching from sort mode by input and selecting plate mode, check whether the bin matches the home position 1 and check whether the HPIJ turn command has been selected. In order to check and return the bottle to the home position with command a,
The LIB routine is executed, but if there is no command, the bin will be shifted by one, so SFT SUB , A/-
The plan is to execute Chin.

Figure 14 is a self-diagnosis SUB routine that monitors the operation of the sensor turned on and off by the bin shift of the sorter, and if there is an abnormality, sets a trouble command and notifies the operator of the abnormality and proceeds to the JAMRESET SUB routine. It is.

Step? It is monitored whether or not the bin moving motor is being driven in Ol, and if it is being driven, the process proceeds to Step 702, and if it is not being driven, the process proceeds to Step 703K.

Step 702 monitors whether there is (REV) detection while the bin is moving, so it is checked whether there is a change in (REV) during the period when the [self-diagnosis timer] ends, that is, whether the bin moves normally. Abnormalities in the bin moving motor and abnormalities in (REV) are checked by monitoring.

Also, in Step▼03, if the bottle is 7}L, (HP
) is detected, it is determined that (HP) is abnormal, and if (UL) is detected when the bin is in the home location, it is determined that (UL) is abnormal.

Figure $15 is the JAMRESET StJB routine, which notifies the operator of the abnormal condition, stops the load L%, and monitors the release of the abnormal condition.

In Step 201, the JAM command indicating the JAM status is sent, the bin movement motor and paper transport motor are turned off, the display data corresponding to the selected mode is saved, and at the same time, the three displays NSTLD, STLD, and CLTLD flash. This will notify the operator of any abnormalities.

In Step 202, check (JNT) detection,
If there is an error, the copying machine will be notified of the sorter error (S
JAM) signal. The main body of the copying machine then performs processing such as prohibiting copying operation. On the other hand, when the operator turns off (JNT) detection to clear the abnormality, (SJ
By turning on the AM) signal, even if there is an abnormality in the sorter, the copy operation prohibition can be canceled by moving the sorter away from the main body of the copying machine.

In Step 203, for the self-diagnosis SUB routine,
Since this is a trouble condition that is determined when there is abnormal water in the sensors that control the operation of the sorter, canceling the error is prohibited. If the bin shifts due to being stuck between the roller and the bin, it may be difficult for the operator to eject the jammed copy sheets. Cut b
Each time the (KEY) input is turned on when the key is released, the manipulator operates to shift the bins one by one without changing the mode selection. This makes it easy to eject the sandwiched copy sheets.

The Stap 204 is structured so that whether or not to perform the above-described operation can be selected depending on the presence or absence of the above-mentioned (DPU) input.

Step $! In 05, in order to move the bin each time there is a (KEY) input, execute RETSOB, which will be described later, and SFTSUB, which will be described above. I'm looking forward to it. Step
In step 205, if there is no shift command, the bin is moved back, and if there is a shift command, the bin is shifted. RETSUB routine is Step 208
As shown in the figure, the bottle is returned by reversing the bottle moving motor, and the motor is turned off when (RELI) detects one rotation, that is, when the l-pin return is completed. By this Step 205 [K
EY) Each time the input is turned on, the operation is first performed to return one bin at a time, and when the bin finally reaches the home position, the next operation is shifted one bin at a time, and when the bin reaches the upper limit position. starts to return one bin at a time again.

Step 206 To release the abnormal state, monitor the ejection of the jammed cobby sheet depending on whether the (PAP) detection turns off, and then set the sorter in the copier body after turning it off (JNT) Monitor with detection turned on, and if the process is successful, perform error cancellation.

Step 207 is a step for canceling the error, and S
The display data saved in step 201 is restored, the selection mode is returned to the mode before the abnormality, the JAM command is reset, and in order to take a predetermined time interval when the abnormality is cleared, wait for the end of the (JAMRESgT timer) and return to the main Return to routine. This (JAMRESET timer)
For example, if the (PAP) is activated due to vibration when the sorter is inserted into the copier body, the (PAP) is set to prevent the operation of sheeting the bins in the printer mode selection. It is designed to be equal to or larger than the time required to eliminate false detections due to vibration.

Also, as an example of the mode selection switching timing mentioned above,
If you switch to collate mode while operating in sort mode,
If the switching timing is while a copy sheet is being conveyed, the mode is switched to the collate mode at the end of conveyance b1 The remaining J sheets are stored in the bin at that pin position, but if the bin is being shifted At the position where the bin has finished shifting, the remaining copy sheets are stored. Next, when the copy start key is turned on while in the current mode, the pin will perform the same plate operation as the home position key K.

Furthermore, if the mode is switched to the sort mode during the non-sort mode, the bin shift is performed after the copy sheets have been conveyed, and the operation continues in the sort mode.

If the above-mentioned mode selection switch is changed while a copy sheet is being conveyed, the copy sheet may be conveyed incorrectly, 9 JAM
If the jam occurs, the mode to return to after the JAM is released will be the mode in which it was switched.b1 Also, if the sorter is turned off due to the sorter being jammed, the mode selection after turning it on again is the same. It is planned to be in the mode of
