2. Description of the Related Art Conventionally, it is well known that a sheet post-processing device can be connected to an image forming apparatus and a sheet output by the image forming apparatus is discharged (stapling, punching, etc.).

Further, in a single image forming apparatus, an interrupt mode function is also well known which can be set during operation of a normal job mode to set another job mode.

[0004]

In recent years, with the diversification of output forms desired by users, the corresponding post-processing devices have become larger in size and higher in cost, and are suitable for all image forming devices connected by a network. Thus, it is an obstacle to connecting a post-processing device having a similar function.

Therefore, it is desired that the output paper from the image forming apparatus which is not connected to the sheet post-processing apparatus is subjected to the same processing as that when the connected image forming apparatus outputs.

Furthermore, it is also desired to perform complicated processing by combining the processing from the connected image forming apparatus and the paper of another image forming apparatus.

As described above, in the case of supporting a plurality of image forming apparatuses, a plurality of jobs are frequently overlapped and set, and an interrupt function beyond the image forming apparatuses is desired.

In particular, when connected to a network, there are many opportunities for remote control, and it is necessary to visit the actual device and check the state of the device.

The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to form an image by which a plurality of information processing devices or sheet post-processing devices can be connected via a predetermined communication medium. A job management apparatus capable of communicating with a plurality of image forming apparatuses including an apparatus, a plurality of information processing apparatuses or a sheet post-processing apparatus via a predetermined communication medium, or a job management apparatus capable of communicating with a plurality of image forming apparatuses. When a job processing interrupt request is accepted during job processing involving processing, it is determined whether a job involving sheet post-processing can be interrupted based on the job processing status using the sheet post-processing device. By interrupting the job processing being executed based on the above, and controlling whether or not the interrupt job can be executed, it is possible to enable multiple information processing devices to communicate with each other via the communication medium. When a job using the sheet post-processing apparatus is processed in line or off-line, when a job interrupt request involving sheet post-processing for a sheet output from any or a plurality of image forming apparatuses is requested, It is possible to determine whether or not a job requested to be interrupted can be executed, and to flexibly respond to network interrupt requests involving sheet post-processing from multiple information processing devices via communication media, and freely build a network image processing system environment.

FIG. 3 is a block diagram illustrating a configuration of the display unit 211 shown in FIG.

In FIG. 12, since the image data output from the core unit 206 is CMY data, the inverse LOG
The conversion unit 1101 needs to convert the RGB data.
Next, a display device 110 such as an output CRT is output.
In order to match the four color characteristics, the gamma conversion unit 1102 performs output conversion using a look-up table. The converted image data is once stored in the memory unit 1103 and displayed on the display device 1104 such as a CRT.

Here, the display section 211 is used for previewing the output image in advance, proofing function for verifying whether the output image is the intended one, or the image not requiring printing. This is to avoid waste of print paper when checking.

[Structure of Finisher Unit 210] FIG.
FIG. 3 is a schematic cross-sectional view illustrating the configuration of the finisher section 210 shown in FIG.

In FIG. 13, the sheet exiting the fixing unit 940 (or 1040) of the printer unit 209 enters the finisher unit 210. The finisher unit 210 has a sample tray 1001 and a stack tray 1002, which are switched and discharged according to the type of job and the number of discharged sheets.

There are two sort methods, a bin sort method that has a plurality of bins and distributes to each bin, an electronic sort function to be described later, and the bins (or trays) are shifted to the front side and output for each job. There is a shift sort method that sorts sheets, and sorting can be performed by both sort methods.

Note that the electronic sort function is called collate, and if the large-capacity memory described in the above-mentioned core section is provided, this buffer memory is used to change the order of buffered pages and the order of discharge. By using the so-called collate function, the electronic sorting function can be supported. Next, the group function is a function that sorts each job, whereas sorting sorts each job.

Further, when the sheets are discharged to the stack tray 1002, it is possible to store the sheets before the sheets are discharged for each job and bind them by the stapler 1005 immediately before the discharging.

In addition, a Z-folding machine 1004 for folding a paper into a Z-shape and a puncher 10 for punching two (or three) holes for a file before reaching the above-mentioned two trays.
06, each processing is performed according to the type of job.

Further, the saddle stitcher 1007 binds the central portion of the sheet at two places, and then half-folds the sheet by engaging the central portion of the sheet with the rollers.
Performs the process of creating booklets such as weekly magazines and pamphlets. The sheets bound by the saddle stitcher 1007 are discharged to the booklet tray 1008.

In addition, although not shown in the drawing, it is possible to add binding (gluing) for bookbinding, or trim (cutting) for aligning the end surface on the opposite side to the binding side after binding. Is.

The inserter 1003 is the tray 111.
Tray 1 without passing the sheet set to 0 to the printer
001, 1002, 1008. As a result, the sheet set in the inserter 1103 can be inserted (middle insertion) between the sheets sent to the finisher 210.

It is assumed that the tray 1110 of the inserter 1103 is face-up set by the user, and the pickup roller 1111 feeds sheets in order from the uppermost sheet. Therefore, the sheet from the inserter 1103 is directly conveyed to the trays 1001 and 1002, and is discharged in a face-down state. When sending to the saddle stitcher 1007, once the puncher 10
After sending it to the 06 side, switch it back and send it to match the face direction.

[Network 101] Next, the network 101 will be described.

FIG. 14 shows the network 10 shown in FIG.
FIG. 3 is a diagram illustrating an example of a network configuration including 1;

In FIG. 14, the configuration shown in FIG. 1 is connected by a device called a router for mutually connecting networks, and a LAN (Local Area Ne
Configure a further network called a network.

The LAN 1306 is the internal router 1
Another LA via 301 and leased line 1308
It is connected to the router 1305 inside the N1307, and these networks are stretched in multiple layers to form a vast connection form. An example of the data flow on the network is as shown in FIG.

FIG. 15 shows the network 10 shown in FIG.
2 is a diagram for explaining the flow of data on 1.

In FIG. 15, there is data 1401 existing in the transmission source device A (device 1400a),
The data may be image data, PDL data, or a program. This is network 101
When the data is transferred to the device B (device 1400b) of the reception destination via the, the data 1401 is subdivided and image-wise divided like the data 1402. A destination address called a header 1405 (an IP address of the destination when the TCP / IP protocol is used) and the like are added to the divided data 1403, 1404, 1406, etc., and the packets 1407 to 1409 are sequentially networked. Send a packet on 101. When the address of the device B and the header 1411 of the packet 1410 match, the data 1412 and 1413 are separated, and the data 1415 and 1416 in the device A are reproduced.

[Printer Driver] Next, the process of transmitting image data from the printer controller 102 or the client computer 103 to the printer by the printer driver will be described with reference to FIG.

FIG. 16 is a diagram showing an example of the printer operation screen displayed on the display device connected to the printer controller 102 or the client computer 103 shown in FIG. 1, and the printer driver is used to instruct the printing operation. This is a GUI, and by instructing this, the user can instruct desired setting parameters and send a desired image to a destination such as a printer.

In FIG. 16, 1601 is a printer driver window in which user-settable setting items are displayed.

Reference numeral 1602 denotes a transmission destination selection column for selecting a target output destination. Generally, the aforementioned MFP
104, 105 or the printer 107.

Reference numeral 1603 is a page setting column for selecting an output page from the job, and determines which page of the image image created by the application software operating on the printer controller 102 or the client computer 103 is output.

Reference numeral 1604 is a copy number setting column for specifying the number of copies. Reference numeral 1607 denotes a property key for making detailed settings for the destination device selected in the destination selection column 1602. Click here to enter device-specific setting information on a separate screen for special image processing. For example, by changing the parameters of the gamma correction unit 702 and the spatial filter 708 in the printer IP unit 207, finer color reproduction and sharpness adjustment can be performed.

When the desired setting is completed, the OK key 1
Printing is started by 605. When canceling, printing is canceled by the cancel key 1606.

A finishing setting column 1608 is
The setting items for the finishing process are different depending on the function of the selected printer or the installed resource. The destination selection column 16
Printers and MFPs that can print by clicking on the right side of 02
Etc. is displayed, but to do this, you need to search for a printer on the network.

Specifically, the MF on the network 101
When searching for P or a printer, a so-called directory service is used. The directory service is, so to speak, a telephone directory related to the network and is used for storing various information. As an example of a directory system using the above directory service,
For example, LDAP (Lightweight Direc)
There is a tory Access Protocol).

The above-mentioned LDAP rules are IETF (Int
ernet Engineering Task Fo
RFC (Re), which is a standard specification issued by
quest For Commets) 1777.

By using the above directory service to search for a device connected to the network,
You can get a list of network addresses of devices available on the network. The computer 102 on the network 101 functions as an LDAP server and stores all information about devices on the network. The computer can search for a desired device by inquiring the LDAP server instead of searching for it by itself.

By registering the position information of the device in accordance with the equipment information and the state of the device, it is possible to search for a device close to a computer or a printer closest to a desired printer and having a desired function. Is.

The position information defines, for example, the distance from the reference point for each floor in the XY directions, and also adds floor information and the like.

For example, if it is said that the corner of the second floor is 3 m in the X direction (a distance such as the third pillar may be used) and 5 m in the Y direction, information such as 3X5Y2 is given.

Using such a directory service, the driver can display a list of printers in the destination selection column 1602 by inquiring the LDAP server.

The conventional printer driver cannot select two printers at the same time, but in this embodiment, a key 1609 for selecting the next printer is provided.

By pressing this key, a further printer selection column is displayed, and the second printer or finisher can be selected.

When selecting another printer, the order of printer selection can be changed by pressing the property key (property key) 1607 to go to another setting screen.

When the right end of the printer selection column 1602 of the normal printer driver is clicked with the mouse, a list of selectable printers is displayed. At that time, as shown in FIG. 17, the printer displayed at the top of the list display can be changed according to various conditions. As a result, for example, it becomes easy to make a selection on the condition that the MFP is the closest to the first selected MFP.

FIG. 17 shows the printer controller 1 shown in FIG.
02 or an example of a printer operation screen displayed on a display device connected to the client computer 103, and corresponds to the screen example displayed when the property key 1607 shown in FIG. 16 is pressed.

Further, when processing cannot be performed in the order of combination when two units are selected, for example, punching cannot be performed after stapling. In that case, a warning is displayed.

When the desired setting is completed, printing is started by the OK key 1605. When canceling, printing is canceled by the cancel key 1606.

[Explanation of Network Utility Software] The utility software operating on the computer 102 (or the client 103) will be described below.

In the network interfaces of the MFPs 104, 105 and 106 and the finisher 109, there are M
IB (Management Information)
A standardized database called Base) has been constructed, and SNMP (Simple Network)
It is possible to communicate with a computer on a network through a network management protocol called k Management Protocol), and manage the MFPs 104 and 105, a scanner, a printer, or a FAX connected to the network.

On the other hand, a software program using MIB is running on the computer 102 (or the client 103), and the above S
Necessary information exchange becomes possible by using MIB by using NMP.

IfPhys defined in RFC1213
Address, sysObjectID and RFC
MI such as hrDeviceID defined in 1514
By acquiring the B information, the information specifying the device can be obtained. Equipment information and capabilities of the device are defined as the private MIB, and it is possible to detect whether or not the finisher is connected as the equipment information.

Further, even if the devices on the network are M
By acquiring the IB information, it is possible to communicate with each other and acquire information such as the status and capability of the device of the other party.

The computer 102 constantly communicates with the devices on the network or keeps track of the functions, states, etc. of each device by transmitting from each device. Since the WEB server is constructed based on the MIB data collected from each device, the computer 103 uses the well-known browsing software based on HTTP for the computer 10.
It is possible to grasp the state of each device even when accessing 2.

All the print jobs are once thrown to the computer 102, and then the JOB is input from the computer 102 to each printer, and the user name, department, file name, number of pages, JOB contents, etc. of the JOB are analyzed and the user The number of prints and the total number of pages in each unit or department are stored. Further, by managing the number of prints of each device, the number of errors, the current remaining amount of paper and toner, and the like, it is possible to manage and operate devices on the network and jobs.

Further, the computer 102 also converts the printing protocol. For example, if the MFP 105 is L
Although only PD is supported, IPP (Internet Printing Pr)
computer 102, the computer 102 automatically converts to LPR and the MFP 105
It is possible to throw a JOB at.

The printed data is stored in the memory 108.
The server automatically erases it according to parameters such as the remaining memory and date.

[Explanation of GUI] Next, GUI (Grap)
A screen of utility software that operates on the computer 102 (or the client 103) called "hic User Interface" is shown in FIG.
8, and will be described with reference to FIG.

18 and 19 are diagrams showing an example of the GUI displayed on the computer 102 (or the client 103) shown in FIG.
When the utility software is started up (or the client 103), the screens shown in FIGS. 18 and 18 are displayed.

In FIG. 18, 1701 indicates a status tab for opening a status page, 1702 indicates a JOB tab for opening a page for operating a print JOB inside the printer, 1703 indicates equipment of the apparatus and the like. An information tab for opening a page to be confirmed is shown, and 1704 is a network tab for opening a page for making network settings.

On the other hand, FIG. 18 shows a state in which the status page is displayed, 1705 is an external image of the apparatus, and an image corresponding to equipment information such as a finisher or a deck is displayed.
On the right side, the information on the paper contained in each cassette is displayed as the information on the paper feed stage. Reference numeral 1706 indicates the operating state of the apparatus, which changes according to the operating state. This allows the user to easily visually confirm whether or not there is a finisher for the image processing apparatus that the user is going to select, whether or not there is a finisher option, and the like.

[Add-on] The addition of a command to be added-on will be described below with reference to FIG.

FIG. 20 is a schematic diagram for explaining add-on processing in the image processing system according to the present invention.

In FIG. 20, an original image 1801 is image data created by application software on the computer 102 (or the client 103), and a command image will be given to this.

The add-on information is, for example, the image pattern 18
02, which is information for performing the paper discharge process created by the above-described print driver when transferring the image data created on the computer to the apparatus of the present embodiment, such as staple, punch, and insert. The sensor 1009 of the finisher reads the operation instruction, the number of pages, and the like, and then the finisher operates the paper discharge process based on this information.

[Additional Pattern] FIG. 21 is a diagram illustrating an example of an additional pattern in the image processing system according to the present invention.

In FIG. 21, in the case of 200-line processing, the 4 × 4 pixels included in the area 1901 are modulated so that the gradation of the image signal becomes + α, and the 4 × 4 pixels included in the areas 1902 and 1903, respectively. The 2 × 4 pixels are modulated so that the gradation of the image signal becomes −α, for example, and the pixels other than the regions 1901-1903 are not modulated. Then, 8 × 4 pixels included in the regions 1901-1903 are set as unit dots of the additional pattern. In the case of 400 line processing, 4 × 4 pixel processing is performed. Further, in the case of 100 line processing, 2 × 2 or 1 pixel is used as an additional pattern. Since the processing method is the same, the description will be given below using 8 × 4 pixels as an example.

22 and 23 are diagrams showing an example of the add-on line in the image processing system according to the present invention. FIG. 22 shows the structure of the add-on line in the main scanning direction, and FIG. 23 shows the add-on line in the sub-scanning direction. Online configuration is shown.

In FIG. 22, 2001 is an add-on line having a width of, for example, 4 pixels. 2001a-2001
e is the unit dot shown in FIG. 21, for example 8 ×
It has 4 pixels. The unit dots 2001a to 2001e are
They are arranged in the main scanning direction at a substantially constant period of d1 to d3 (for example, 128 pixels).

Further, in FIG. 23, 2101 to 211
0 is an add-on line, which has a width of, for example, 4 pixels, and is arranged in the sub-scanning direction at a substantially constant period of d2 (for example, 16 pixels). Although details will be described later, for example, one add-online represents 4-bit information, and
~ 2109 8 ad online as a set 3
Two bits of additional information can be represented. The add-on lines are repeatedly formed in the sub-scanning direction, and the add-on lines 2101 and 2109 shown in FIG. 23, for example, represent the same information sequentially and repeatedly.

FIGS. 24 and 25 are diagrams showing an example of a method of expressing information by the add-online shown in FIG.

In FIG. 24, 2201 and 2202 are add-on lines, and both add-on lines are adjacent to each other in the sub-scanning direction. 2201a, 2201b and 2202
a is a unit dot, and adjacent add-online unit dots are adjacent to each other in the main scanning direction by at least d in order to prevent adjacent add-on unit dot comrades from approaching and conspicuous.
It is set so that an interval of 3 (for example, 32 pixels) is opened.

The data represented by the unit dot is determined by the phase difference between the unit dot 2202a and the unit dot 2201a.

FIG. 24 shows an example of 4-bit information, but the unit dot 2202a represents data "3". For example, if the unit dot 2202a is at the leftmost end, the data "0" is represented, and if the unit dot 2202a is at the rightmost end, the data "F" is represented.

In FIG. 25, of the set of add-on lines representing all the additional information, the line shown in (a) is the first add-on line Line 0, and the line shown in (b) is 4.
Represents the third add-on line Line3. As shown in FIG. 23, in Line 0, the original unit dot 2301a
To 2301d, dots 2302a to 2302d are added at intervals of d4 (for example, 16 pixels), and the original unit dots 2304a to 2304a to Line3 are added to Line3.
To the right of all 304d, d5 (eg 32 pixels)
Dots 2305a to 2305d are added at intervals of. These additional dots are markers for clarifying the order of each ad online.

The reason why the markers are added to the two add-on lines is that the upper and lower sides in the sub-scanning direction can be determined even from the output image.

The pattern to be added is, for example, an MFP.
In the case of a full-color MFP such as 104, the Y-color information is added only by utilizing the fact that the human eye has a low identification ability with respect to a pattern drawn with Y toner.
As a result, when printed out, no additional information is attached. When this information is added as black information, it is added as a visible image.

Further, in the case of a monochrome MFP such as the MFP 105, it is 256, for example, to the extent that it cannot be seen by human eyes.
If it is a density signal of gradation (8 bits), the signal value is -8
A value of about +8 is added and added as add-on information.

Further, the dot interval in the main scanning direction of the additional pattern and the repeating interval of all additional information in the sub scanning direction are
It is necessary to determine that all information is surely added to a thin and uniform area where dots can be surely identified in a specific original document. As a guide, information may be added at a pitch that is ½ or less of the width of a thin and uniform area that allows dots to be reliably identified in the target specific document.

When adding both the user information and the paper discharge processing information, it is conceivable to add them alternately, or to replace the information at every specific cycle. Also,
Since the Y add-on information and the black density conversion information can be mixed, they can be added at the same position.

The additional information printed out cannot be visually identified, but when read in the present embodiment, the information can be sufficiently identified. However, if this information is further copied, this information will be lost. Therefore, even if the copied paper is set in the finisher of this embodiment, the command is not effective.

[Add-on Unit 212 in MFP 104, 105] Next, a method of adding an add-on will be described. This corresponds to the add-on unit 212 of FIG. 2, and its circuit will be described with reference to FIG. 26, for example.

FIG. 26 shows the add-on unit 212 shown in FIG.
3 is a circuit block diagram illustrating a configuration example of FIG.

In FIG. 26, the rasterized image signal 2401 is input from the PDL unit 205. At this time, the add-on data is the image signal 240 from the add-on information page memory 2402 in which the add-on information as described above with reference to FIGS.
It is output in synchronization with 1.

That is, the add-on information page memory 24
In the inside of 02, it is stored as add-on data in an information format as shown in FIG. 27, for example, in an 8-bit data format in which the most significant bit is a code bit in the data of “-127” to “+127”. The part of "+4" and the part of "-4" are denoted by reference numerals 1901 to 19 in FIG.
It corresponds to the part of 03.

FIG. 27 is a diagram showing an example of the data format of the add-on information stored in the add-on information memory shown in FIG.

Referring again to FIG. 26, the image signal 2401 and the add-on information page memory 24 read in synchronization with each other.
The add-on data No. 02 is input to the adder 2403 or the subtractor 2404, and as a countermeasure when it is saturated more than “FFH” or less than “00H”, the carrier signal and the OR gate 2405 or the AND gate 2406 are used. Through the selector 2407. The select signal 2408 of the selector 2407 is the most significant bit (sign bit) of the add-on information page memory and is switched depending on whether the add-on information is positive or negative as shown in FIG. 27, and the image signal 2409 is sent to the core unit 206.

On the contrary, when the image signal 2401 is already added with the add-on data, the most significant bit (sign bit) of the add-on information page memory 2402 can be reversed to cancel the signal. The movement is reversed,
If it is the same add-on data, it will be canceled.

The add-on addition circuit is added to the YMC and K signal systems. Each pattern can be added to an image by writing an additional pattern in each page memory 2402.

If the pattern is written only in the Y page memory, only the Y page is added. In the case of black add-on, if an additional pattern is written in the K page memory, the black add-on will be added.

[Network Interrupt Function] This function is
This is a function for performing emergency output separately from the continuous output. In this system, the interrupt function is set by the computer 10 connected by the network 101.
2, the client 103, the operation unit 209A of the printer,
It can be set by the operation unit 210A of the finisher unit 210.

This interrupt function is performed by the finisher unit 210.
The present invention is not limited to the job of the printer unit 209 to which is connected, and it also effectively functions when the output paper from another printer is processed by the finisher 210.

This interrupt function is performed, for example, by the core unit 206.
The CPU 206A manages the job on the internal memory and is processed by the finisher unit 210 by the interrupt function, and determines whether the interrupting mode can be processed while the job is temporarily stopped. If processing is possible, the interrupted job is resumed, and then the stopped job is restarted.

If it is determined that interrupt processing is not possible, it is not necessary to interrupt the job being processed, and the operator is notified by an alarm.

Next, referring to the flow chart shown in FIG. 28, the operation of each device in the case of performing printing and paper discharge processing,
In this processing example, a case where stapling processing is performed on a document in which black and white and color are mixed will be described.

FIG. 28 is a flow chart showing the first data processing procedure in the image processing system according to the present invention. Note that S101 to S115 indicate each step.

First, in step S101, the operator operates the terminal of the computer 103. An original of mixed color black and white is created by well-known DTP software or the like.

Next, in step S102, when printing is performed, the screen of the printer driver shown in FIG. 16 is displayed on the display of the computer 103. Then, stapling is designated by the finishing setting column 1608 on the screen of the printer driver. Further, the printer is designated in the transmission destination selection column 1602. If the finishing function or the like is unclear, detailed information is displayed by pressing the key 1602 to know the details (not shown).

Since the original is mixed in color and black and white, it is necessary to specify a black and white printer and a color printer.

Therefore, in step S102, the printer selection column 16 is displayed on the setting screen of the printer driver.
At 02, the monochrome MFP 105 on the network is selected as the first printer candidate. Where the key 160
By pressing 9, the further printer selection column becomes valid and the second printer or finisher can be selected. In step S103, the color MFP 104 is selected as the second printer candidate.

Then, when the OK key 1605 is pressed on the printer driver setting screen shown in FIG. 16, the process proceeds to step S104, and as shown in FIG.
A window prompting the user to display a number and enter a password is displayed on the display of the computer 103.

FIG. 29 shows the computer 103 shown in FIG.
It is a figure which shows an example of the user identification information input screen displayed above.

In FIG. 29, the job number is an arbitrary number created by the computer 103 and the operator logs in.
The added character string and the like serve as information for identifying the operator and the manuscript.

A password is necessary for the operation described later, and for example, a combination of alphabets and numbers within 8 characters is input. Then, O on the screen shown in FIG.
When the K key is pressed, next, in step S105, the computer 103 creates print data. To this print data, along with the conventional PDL drawing data, commands such as stapling processing, monochrome / color mixed processing, interlocking of two units, and add-on processing are added.

The paper discharge process is performed in the transmission destination selection column 160.
The MFP selected first in step 2 does this, or if the finisher is selected, the finisher is prioritized.

Then, when the creation of the print data is completed, the data is transferred to the two designated MFPs 104 and 105 on the setting screen of the printer driver shown in FIG.

Next, in step S106, when the print data transferred from the computer 103 is received by the MFP 105, the processing command in the transferred print data is analyzed, and only the black and white page is rendered and temporarily stored in the memory. Accumulate data. At that time, add-on is not performed.

Then, in step S107, the MFP 1
Reference numeral 04 analyzes the print data and draws only the color page, and the processing command in color, the job number and the page number input by the printer driver, etc. are added in yellow to start printing.

When the printing is completed, the end notification is sent to the computer 103. The print data is stored in the memory 108 shown in FIG.

Next, in step S108, since the color printing is completed, the computer 103 is instructed to set the ejected paper in the finisher of the MFP 105 (the display screen is not shown). This display is also displayed on the operation unit of the MFP.

Then, in step S109, the operator
The paper is taken from the paper discharge unit of the FP 104 and set on the insert tray 1003a of the finisher of the MFP 105. Enter the job number on the operation unit of the finisher or the operation unit of the MFP 105, or
Is displayed, and job is specified from the list. At this time, the job number is directly input, and the number j
If there is no ob, a warning is displayed. If the processing is still in progress, the warning is displayed as such. When the job is specified, the password is input. This is the password displayed in the window shown in FIG. In addition, a warning message will be displayed even if the password cannot be processed by others and the password is incorrect.

When a sheet is set on the tray and the starter start key (not shown) of the finisher is pressed, the finisher causes the sensor to read the add-on information while moving the sheet to the tray 1003b. The job number is read from the add-on information and the password input standby state is entered.
If the order of the devices to be set is different, a warning is displayed on the operation unit.

When the password is normally input in this way, the process proceeds to step S110, and the MFP 105 reads the data for which the drawing process has been completed from the memory and performs the paper discharge process. At this time, the paper is discharged in consideration of the order with the paper on the tray 1003 of the finisher.

For example, if the first and second pages are output from the MFP 105 and the third page is the first page of the MFP 104, the page number of the add-on information is “3”, and the MFP 105 ejects up to the second page. Then, the finisher feeds the sheet corresponding to the third page from the tray 1003b. This is the case of the back side sheet discharge, and in the case of the front side sheet discharge, the sheet is discharged from the last page.

If it is determined in step S111 that the paper from the tray 1003 has jammed and it is determined that a jam has occurred, step S1
In step 12, the JAM is displayed on the screen of the operation unit, and a display prompting whether to reprint the JAMed paper is displayed.

Then, when the operator judges that the JAM-generated paper cannot be used and presses the reprint key, the process proceeds to step S113, and the finisher requests the MFP 104 to print only the JAM page.
Then, the MFP 104 executes reprinting.

Next, in step S114, the operator selects the MF
When the paper is taken from P104 and set in the tray 1003, the recovery operation is performed. Then, step S115
Then, when all the paper is ejected and finishing processing such as stapling and punching is completed, the computer 1

The data of No. 8 is erased, and a series of processing operations is completed.

Next, the MFP 106 and the finisher 1
The processing operation of 09 will be described with reference to the flowchart shown in FIG.

FIG. 30 is a flow chart showing the second data processing procedure in the image processing system according to the present invention. Note that S201 to S216 indicate each step.

First, in step S201, the operator operates the terminal of the computer 103 to create a print data by operating a well-known DTP software or the like on a document of mixed color black and white. Before starting the printing process, the state of each device is checked. This state check process is performed as shown in FIG.
As shown in FIG. 7, the display is performed by operating the utility software to acquire the status of the device such as the MFP on the network.

Next, in step S202, the MFP 106
When the key for disconnecting the connection between the MFP and the finisher is pressed while not displayed (not shown), the MFP 106 becomes the MFP without the finisher. Further, the separation can be set by the operation unit of the MFP 106 or the finisher 109.

31 and 32 are diagrams showing an example of the network status display screen displayed on the display device of the computer 103 shown in FIG. 1, and correspond to the display in the administrator mode.

The display shown in FIG. 31 is based on the function of displaying a list of devices connected to the network, which is called a device list provided in the utility software, before the main body and finisher of the MFP 106 shown in FIG. 1 are separated. 3 MFPs (device name: 300-405, CP660 PS-AP, iR5
(000-6000), the finisher 109 starts the independent operation to support the SNMP by disconnecting the connection state of the finisher from the main body, so that the finisher 109 also supports the SNMP as shown in FIG. It will be displayed on the device list.

Next, in step S203, when the operator confirms the status of the device he / she wants to print and prints, the display (display device) of the computer 103 displays the printer driver shown in FIG. Is displayed.

Then, in step S204, in the printer selection column 1602 on the printer driver screen, the first
For example, the black and white MFP 106 is selected as the printer candidate of.

Next, in step S205, the color MFP 104 is selected as the second printer. Further, the finisher 109 is selected to specify stapling. In this case, even if the finisher is specified in the MFP 104 or the like because the finisher is designated, the setting for the finisher 109 is given priority, or if there is a process that is not in the finisher 109 and can be performed by the finisher of the MFP 104, the setting is also performed. It becomes effective.

Then, in step S206, the OK key 1
When 605 is pressed, the ID information input shown in FIG. 29 is prompted, that is, the job number display and password input window are displayed. Here, the job number is an arbitrary number created by the computer 103,
Ginned character strings and the like are added and serve as information for identifying the operator and the document. The password is necessary for the operation described later, and for example, a combination of alphabets and numbers within 8 characters is input.

Next, in step S207, the OK key on the display screen shown in FIG.
3 creates print data. This print data includes stapling, monochrome / black and white, as well as conventional PDL drawing data.
Commands such as mixed color processing, interlocking of two units, and add-on processing are added.

The paper discharge process is performed in the column 1 shown in FIG.
The MFP selected first in step 602 does this, or if the finisher is selected, the finisher is prioritized.

When the creation of the print data is completed, the print data is transferred to the two MFPs and the finisher 109 designated by the user. On this occasion,
The transfer protocol is performed by well-known LPR or the like.

Next, in step S208, the MFP 106
Analyzes the processing command in the transferred print data and draws and outputs only the black and white page. Upon completion, the computer 103 is notified of the end notification.

The color MFP 104 also analyzes the data, draws only the color page, and starts printing. When printing is completed, the computer 103 is notified of the end notification. Job numbers and page numbers are added to all the devices.

Next, in step S209, when the printing is completed, the computer 103 displays an operation screen prompting the user to set the discharged paper in the finisher 109. This display is also displayed on the operation unit of each device.

Then, in step S210, the operator removes the paper from the paper discharge section of the MFPs 104 and 106, and insert trays 1003a and 1003c of the finisher 109.
Set the paper on. Then, the job number is input on the operation unit of the finisher, or a list of jobs is displayed, and the user selects and specifies the job from the list. At this time, the job number is directly input, and if there is no job with that number, a warning display is displayed. Further, if the processing is still in progress, the warning is displayed as such.

When the job is designated in this way, the password (password displayed in FIG. 29) is input. This is to prevent others from processing once, and at this time, if the entered password is incorrect, a warning to that effect is displayed.

When paper is set in the tray and the starter key (not shown) of the finisher is pressed, the finisher reads the add-on information by the sensor while moving the paper to the trays 1003b and 1003d. The job number is read from the add-on information and the password input standby state is entered. If the order of the devices to be set is different, a warning is displayed on the operation unit.

Further, in the case of handling a sheet having no finisher add-on information, it is possible to set the processing of the sheet on each insert tray by the operation section of the finisher.

Next, in step S211, when the password is also entered normally, the sheets in the tray 1110 are fed in the designated order and the finishing process is performed.

Then, in step S212, the tray 10
Judge that the paper from 03 is JAM,
If it is determined that the paper is JAM, step S
Proceeding to step 213, a display for notifying the occurrence of JAM is displayed on the display screen of the operation unit, and a display for prompting whether or not to reprint the JAMed paper is displayed.

Next, in step S214, the operator makes a JA
If the reprint key is pressed when it is determined that the paper of M size cannot be used, the finisher 109 causes the MFP 104 to
Alternatively, the MFP 106 is requested to print only the JAM page.

Then, in step S215, the MFP 10
4 prints, and when the operator brings in paper from the MFP 104 and sets it on the tray 1003 on the MFP 106, a recovery operation is performed. At this time, if there is a further finisher, the finish notification is given to the finisher.

Then, in step S216, when all the sheets have been ejected and finishing processing such as stapling and punching has been completed, the computer 103 j
Ob is notified of the end, and the process ends.

When the finisher 109 is reconnected to the main body, it becomes an MFP integrated with the main body, and is not displayed on the device list shown in FIG.

Next, the operation of each device when the server 102 handles a job will be described with reference to the flowchart shown in FIG.

FIG. 33 is a flow chart showing an example of the third data processing procedure in the image processing system according to the present invention. Note that S301 to S315 indicate each step.

First, in step S301, the operator operates the terminal of the computer 103. Print data is created using a well-known DTP software or the like for a mixed color black and white document.

When the operator confirms the status of the device he / she wants to print and prints, the screen of the printer driver shown in FIG. 16 is displayed on the display of the computer 103.

Then, in step S302, the monochrome MFP 105 is selected as the first printer candidate in the printer selection column 1602 on the screen shown in FIG.
Next, in step S303, the color MFP 104 is selected as the second printer candidate. Further, the finisher 109 is selected to specify stapling. In this case, since the finisher is specified, the MFP 10
Even if the finisher 4 or 105 has a finisher, the setting for the finisher 109 is prioritized, or if there is a process that is not included in the finisher 109 and can be performed by the finisher of the MFP 105, the setting is valid.

When the OK key 1605 is pressed in step S304, the window for displaying the job number and password for prompting the ID information input shown in FIG. 29 is displayed. Here, the job number is an arbitrary number created by the computer 103 and is logged by the operator.
The added in-character string and the like serves as information for identifying the operator and the document.

A password is necessary for the operation described later, and for example, a combination of alphabets and numbers within 8 characters is input. Then, O on the screen shown in FIG.
When the K key is pressed, the computer 103 creates print data. To this print data, along with the conventional PDL drawing data, commands such as stapling processing, monochrome / color mixed processing, interlocking of two units, and add-on processing are added.

The paper discharge process is performed by the first MFP selected in the column 1602. Alternatively, when the finisher is selected, the finisher is prioritized.

Next, in step S305, when the creation of the print data is completed, the print data is once transferred to the computer 102. Then, in step S306, the computer 102 analyzes the processing command in the transferred print data, reconstructs the print data of only the monochrome page, and outputs the print command to the monochrome MFP 105. Also, by reconstructing the print data for color pages only,
A print command is issued to the FP 104.

Next, in step S307, each MFP 10
Reference numerals 4 and 105 execute print processing based on the received print data, and when the print processing is completed, the computer 102 is notified of the end of operation.

Next, in step S308, the computer 102 notifies the computer 103 of an end notification.

At this time, since the computer 103 has finished printing, the ejected paper is used for the finisher 10
An operation screen (not shown) that prompts the user to set 9 is displayed.

Then, the operator takes out the color output paper and the black-and-white output paper discharged from the paper discharge units of the MFPs 104 and 105, respectively, and sets the paper on the insert trays 1003a and 1003c of the finisher 109.

Next, in step S309, the operation unit of the finisher 109 logs in the computer 102.
Then, when you select and execute your own job from the list of jobs,
The computer 102 gives an operation instruction to the finisher 109. This instruction is for tray 1003a or 1003c
It contains the order of sheets and processing instructions for each color of paper.

Then, in step S310, the finisher 109 feeds the sheets in the trays 1003b and 1003d in the designated order and performs the finishing process.

Next, in step S311, it is determined whether or not the sheets from the insert trays 1003a and 1003c are JAM. If it is determined that the sheets are JAM, the process proceeds to step S312, and the JAM is input to the operation unit. Is displayed, and an operation screen for prompting whether or not to reprint the JAMed paper is displayed.

Then, in step S313, it is determined that the paper sheet in which the operator has JAM (including the JAM state of being damaged, being cut, or being deformed into a bellows shape) cannot be used. , When the reprint key is pressed,
The finisher 109 provides the computer 102 with a JA
Request to print only M pages. In response to this, the computer 102 outputs a reprint request to one of the MFPs allocated to the JAM page.

Next, in step S314, the operator sets the MF
Bring the reprinted paper from P and put it in tray 100
When set to either 3a or 1003c, a recovery operation is performed.

In the computer 102, when it is necessary to perform processing by another finisher, the finisher 109 is instructed to display an instruction message to the operator. The operator sets the paper in the next finisher according to the display.

Then, in step S315, when all the sheets are ejected and finishing processing such as stapling and punching is completed, j is sent to the computer 102.
When the end notification of ob is sent, the computer 102 totalizes the processing of each device, writes data in the memory 108,
Further, the end of the job is notified to the computer 103, the end is displayed on the computer 103, and the processing operation is ended.

On the other hand, if it is determined in step S3401 that an interrupt job request has been received, the job being executed is suspended (S3402), and the interrupt job requested from the job processing status is selected. Whether or not the job can be executed is determined from the job processing progress information (S3403), and when it is determined that the interrupt job is not executable, step S34.
The process proceeds to step 10, and a warning is issued to the request source device that the interrupt job cannot be executed, and the process ends.

On the other hand, when it is determined in step S3403 that the interrupt job can be executed, step S340
In step 4, the job status information being executed is stored in the internal memory of the core unit 206, and in step S3405, the job processing request accepted from each request source is executed. Specifically, for example, during execution of a print job that does not use the finisher unit 210, if the requester simply makes a finisher request from the finisher unit 210, the print job is temporarily interrupted and the finisher request is interrupted. It will be.

[0240] Next, in step S3406, the CPU 206A determines whether or not the job processing being interrupted is completed, and if not completed, step S3405.
If it is determined that the process is completed, the process returns to step S.
The job status information stored in 3404 is read out (S
3407), the CPU 20 executes the suspended job processing.
6A is restarted (S3408).

Then, in step S3409, it is determined whether or not the interrupted job processing is completed. If not completed, the processing is continued, and if completed, this processing is completed. To do.
