Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. In the description of the drawings, the same elements are designated by the same reference numerals, and duplicate description will be omitted. In addition, the dimensional ratios in the drawings are exaggerated for convenience of explanation and may differ from the actual ratios.

The management server 90 includes a CPU, a memory, a communication unit, and the like, and transfers and / or post-processes paper from each of the image forming systems 10a, 10b, and 10c (hereinafter, these are collectively referred to simply as the image forming system 10). Collect output information (described later) about. The management server 90 may be a cloud server that is virtually constructed entirely by a plurality of servers arranged on a network such as the Internet. The management server 90 can analyze the output information aggregated from each image forming system 10 to predict failures and optimize the delivery timing of consumables.

(Image formation system 10)
FIG. 2 is a front view showing the appearance of the image forming system 10. FIG. 3 is a block diagram showing a hardware configuration of the image forming system 10.

As shown in FIGS. 2 and 3, the image forming system 10 includes an image forming device 100 and post-processing devices 200, 300, 400. The image forming apparatus 100 and the post-processing apparatus 200, 300, 400 are connected in this order. The post-processing devices 200, 300, and 400 are also referred to as post-processing device A, post-processing device B, and post-processing device C, respectively. The paper image-formed by the image forming apparatus 100 and conveyed is post-processed by the post-processing devices 200, 300, and 400 in the subsequent stage according to the setting of the print job. The post-processing device 200 performs reverse transfer of the paper as post-processing. The post-processing device 300 performs a deformation process (hereinafter, also referred to as “first post-processing”) as a post-process for changing the shape of the paper.

The post-processing device 400 performs a finishing process as a post-process. The finishing process includes a binding process (staple, glue booklet), a punching process, a crease process (stripe), and a perforation process, and a discharge process to the discharge trays 491 and 492. If the processing by the post-processing device 400 is not set by the setting of the print job (hereinafter, simply referred to as “print setting”), the discharge trays 290 and the discharge trays 290 provided in the post-processing devices 200 and 300, respectively. It is discharged to 390.

(Output information)
Here, the output information is output result data relating to the transfer and / or post-processing of the paper conveyed from the image forming apparatus 100 to the post-processing devices 200, 300, 400. For example, the paper transfer speed or the transfer time obtained by detecting the paper passing timing by a plurality of paper sensors (described later) provided in the transfer path of the aftertreatment device 300. Alternatively, the processing time (or processing speed) of the post-processing and the dimensional accuracy of the post-processing. The processing time is the time required for one post-processing. Further, for dimensional accuracy, the paper size after deformation processing such as cutting processing may be measured by arranging a reading scanner on the transport path in the post-processing device.

The output information is aggregated by adding identification information (ID) for each of the same image formation conditions. Here, the image forming conditions are a paper type (paper brand), a basis weight, and a paper size, and when these are the same, the same image forming conditions are obtained. The environmental temperature at which the apparatus operates may be added to this image formation condition. For example, when an image is formed on 100 sheets of paper under the same image forming conditions in one print job, these output informations are managed by one ID. That is, 100 pieces (100 data) of output information can be obtained for one ID.

Paper types include plain paper, woodfree paper, color paper, envelopes, embossed paper, gloss coated paper, matte coated paper, and the like. The basis weight is, for example, (a) to 61 g / m ² , (b) 62 to 75 g / m ² , (c) 76 to 81 g / m ² , (d) 82 to 92 g / m ² , and (e) 93. ~ 106 g / m ² , (f) 107 to 136 ^{g / m 2} , (g) 137 to 177 g / m ² , (h) 178 to ^{217 g / m 2} , (i) 218 to 257 g / m ² , (j) 258 It is set in 12 categories of ~ 301 g / m ² , (k) 302 to 351 g / m ² , and (l) 352 g / m ^{2 ~.} Further, the paper size includes innumerable irregular size according to the setting in addition to the standard size such as A3 size, A3, A4, B4, B5, and letter size (8.5 × 11). It is also possible to register a combination of these conditions as a paper brand.

Under these circumstances, tens of thousands of combinations are assumed as image formation conditions (paper type, basis weight, paper size), and the corresponding number of IDs is secured in advance in the image formation system 10. It was difficult to assign. Therefore, in one image forming system 10, every time a print job is executed within a finite range of IDs (for example, 100 to several hundreds), if the print setting is a new image forming condition, a new one is used. An ID is generated and this is given to the image formation condition. Then, every time the output information recorded by the image forming system 10 is transmitted to the management server 90, the output information is deleted, the IDs are reset, and a finite number of IDs are repeatedly generated and used. These controls will be described later (FIG. 7 and the like).

(Image forming apparatus 100)
Refer to FIGS. 2 and 3 again. The image forming apparatus 100 includes a control unit 110, a storage unit 120, a paper feed transport unit 130, a paper sensor 140, an image forming unit 150, an operation display unit 160 and a network I / F (interface) 170, and an internal communication I / F 180. These are interconnected via signal lines such as buses for exchanging signals.

The control unit 110 is a CPU, and controls each of the above units and performs various arithmetic processes according to a program.

The storage unit 120 includes a ROM for storing various programs and various data in advance, a RAM for temporarily storing programs and data as a work area, a hard disk for storing various programs and various data, and the like.

The paper feed transfer unit 130 includes a plurality of paper feed trays, a transfer path, a plurality of transfer roller pairs arranged along the transfer path, and a drive motor (none of which is shown) for driving these transfer roller pairs. .. The paper stored in the paper feed tray is fed one by one and transported by the transport path in the device. The paper fed and conveyed by the paper feed and transport unit 130 is conveyed to the image forming unit 150 one by one along the transport path in the image forming apparatus 100.

The paper sensor 140 is, for example, a plurality of optical sensors provided at required locations on the transport path. Each paper sensor 140 detects the presence (or absence) of paper on the transport path at the installed location, and notifies the control unit 110 of the detection result. The control unit 110 detects the paper transport speed (transport time) based on the paper passing timing and the position information of each paper sensor 140, and the paper exists or exists at the detection position of the paper sensor 140 at a predetermined timing. If not, it detects a transfer abnormality such as jam.

The image forming unit 150 forms an image based on various data on paper by using a well-known image forming process such as an electrophotographic process including each step of charging, exposure, development, transfer, and fixing.

The operation display unit 160 includes a touch panel, a numeric keypad, a start button, a stop button, and the like, and is used for displaying various information and inputting various instructions. The user can set image formation conditions such as paper information (paper type (brand), basis weight, paper size) of the paper stored in each paper feed tray via the operation display unit 160.

The network I / F 170 functions as a transmission / reception unit. The network I / F 170 is an interface for transmitting and receiving data via a network with other devices such as an external management server 90. For example, a device that communicates according to standards such as Ethernet, Bluetooth (registered trademark), and 802.11 (Wi-Fi) is used.

The internal communication I / F 180 indirectly and directly communicates with the internal communication I / F of other post-processing devices 200, 300, 400. The internal communication I / F 180 transmits and receives ID used for storing output information, print settings, various information necessary for operation timing control, paper detection information by the paper sensor 140, information indicating the occurrence of jam, and the like. For example, the image forming apparatus 100 transmits the print settings related to the post-processing included in the print settings of the print job to the post-processing devices 200, 300, and 400 by the internal communication I / F 180.

(Post-processing device 200)
The post-processing device 200 includes a control unit 210, a storage unit 220, a paper transport unit 230, a paper sensor 240, an inversion unit 250, and an internal communication I / F 280, which are mutually connected via a signal line such as a bus. It is connected. The paper transport unit 230 includes a transport path, a plurality of transport roller pairs arranged along the transport path, and a drive motor (none of which is shown) for driving these transport roller pairs. The paper transport unit 230 receives the paper from the device on the upstream side (image forming device 100) and sends it out to the device on the downstream side (post-processing device 300). In addition, the paper is ejected to the ejection tray 290 according to the print setting. If the print setting is set to reverse as post-processing, the paper is sent to the reverse section 250.

The reversing unit 250 has a switchback transport path and has a function of reversing the front and back sides of the paper sent from the paper transport unit 230. The paper whose front and back sides are reversed is sent to the device on the downstream side again by the paper transport unit 230.

Since the other control unit 210, the storage unit 220, the paper sensor 240, and the internal communication I / F 280 have the same functions as the control unit 110, the storage unit 120, the paper sensor 140, and the internal communication I / F 180 of the image forming apparatus 100. , The description is omitted.

(Post-processing device 300)
The post-processing device 300 includes a control unit 310, a storage unit 320, a paper transport unit 330, a paper sensor 340, a deformation processing unit 350, and an internal communication I / F 380, which are mutually connected via a signal line such as a bus. It is connected to the.

The deformation processing unit 350 functions as a "first post-processing unit" and performs a first post-processing that changes the shape of the paper. The first post-processing includes (1) a division process of dividing one sheet into a plurality of sheets, (2) a trimmer process of cutting the edge in the width direction of the sheet and the edge of the front-rear edge in the transport direction. 3) Folding process is included.

(1) In the division process, one sheet of paper is divided into a plurality of sheets, and each of the divided sheets is individually conveyed to the downstream side. For example, the division process includes a cutting process for evenly dividing into two. Hereinafter, the process of dividing into two is also referred to as "two-division process". For example, when one sheet of A3 size paper is divided into two, the shape is changed to two sheets of A4 size paper, and each of them is independently conveyed to the downstream side. (2) In the trimmer treatment, unnecessary parts are cut and discarded. For example, the outside of the register mark placed near the four corners of A3 size paper is cut and transformed into A3 size. In this case, the unnecessary part around the outside is discarded. (3) The folding process includes folding in half, folding in three, folding in Z, and the like. When the deformation processing is not performed, the deformation processing unit 350 also performs a simple transfer process as another post-process. In the following, the deformation processing unit 350 will be described by taking the case of performing the two-division processing as an example.

There are the following problems in performing such a process of changing the shape of the paper. When an ID is assigned for each image formation condition specified by the paper type, basis weight (weight), and paper size, and the paper transport results are collected for each ID, when post-processing accompanied by a change in the paper size is performed. Problems arise. For example, when the cutting process of dividing the paper into two is executed as a post-processing accompanied by the change of the paper size and the transport results related to the series of paper transport of the paper are collected by one ID, the image formation conditions in which the paper sizes are different are set. Since the data is collected and analyzed with the same ID, the credibility of the data is lost, and there is a risk that the failure prediction and replacement time cannot be accurately grasped. The present embodiment also aims to solve such a problem.

The other control unit 310, storage unit 320, paper sensor 340, and internal communication I / F 380 are the control unit 210, storage unit 220, paper transport unit 230, paper sensor 240, and internal communication I / F 280 of the post-processing device 200. Since it has the same function as the above, the description thereof will be omitted.

The post-processing device 400 connected to the rearmost stage includes a control unit 410, a storage unit 420, a paper transport unit 430, a paper sensor 440, a finishing unit 450, and an internal communication I / F 480, which are used for buses and the like. They are connected to each other via signal lines.

The finishing unit 450 receives the paper sent from the device in the previous stage (post-processing device 300 or the like), and executes the discharge process as post-processing to discharge the paper to the discharge trays 491 and 492 according to the print settings. Alternatively, as another post-treatment, a binding process (staple, glued booklet), a perforation (punch) process, a crease process (stripe), or a perforation process is performed according to the print setting.

The other control unit 410, storage unit 420, paper sensor 440, and internal communication I / F 480 are the control unit 210, storage unit 220, paper transport unit 230, paper sensor 240, and internal communication I / F 280 of the post-processing device 200. Since it has the same function as the above, the description thereof will be omitted.

(Functions of each control unit of the image forming system 10)
Next, the functions of each control unit will be described with reference to FIGS. 4 to 6. FIG. 4 is a functional block diagram of the image forming system 10. FIG. 5 is a diagram showing tables 1 to 3 stored in each device when a print job is executed. FIG. 6 is a diagram showing a group table (table 4) stored in the storage unit 120 when a print job with a change in the shape of the paper is executed. Note that FIG. 5 shows an example in which a print job without changing the shape of the paper is executed.

In the embodiment shown below, the aggregation of output information in the post-processing apparatus on the downstream side of the first post-processing unit that performs the first post-processing in which the shape of the paper is changed will be mainly described. Therefore, the description of the processing and the function in the aftertreatment device 200 located on the upstream side of this will be omitted. Although the description is omitted, the post-processing device 200 also has the same functions (giving unit, storage processing unit) as the other post-processing devices (particularly the post-processing device 400) shown below, and is related to the collection of output information. The process is performed in the same manner.

As shown in FIG. 4, the control unit 110 of the image forming apparatus 100 functions as an imparting unit 111 and a first storage processing unit 112. Further, the control unit 310 of the aftertreatment device 300 functions as a collection unit 311 and a second storage processing unit 312. Similarly, the control unit 410 of the aftertreatment device 400 functions as a collection unit 411 and a second storage processing unit 412.

(Granting section 111)
As described above, the imparting unit 111 generates an ID (identification information) for each image forming condition every time a print job of a new image forming condition is executed, and assigns the ID (identification information) to the image forming condition. This ID is used, for example, from a finite range, is reset at predetermined intervals, and is used repeatedly. For example, a finite number of ID numbers, for example, 01 to 100 (100 in total), or AZ (26 in total). However, if you have enough memory capacity, you may generate unique IDs and continue to use an infinite number of IDs (enough to use up).

Further, the granting unit 111 generates an additional ID (additional identification information) in association with the ID when the first post-processing in which the image size changes is executed as described later. The additional ID is a transport device on the post-processing stage (downstream side) of the post-processing device that executes the first post-processing, or on the downstream side of the deformation processing unit 350 (first post-processing unit) in the same post-processing device. It is used when collecting output information on the road. The ID and the additional ID are sent to the first storage processing unit 112 together with the image formation conditions.

(1st accumulation processing unit 112)
The first storage processing unit 112 stores (adds) the ID (including both the original ID and the additional ID) generated by the granting unit 111 in the table 1 of the storage unit 120 in association with the image formation conditions. Further, the original ID and the additional ID generated in association with the original ID are associated with each other and stored in the storage unit 120 as a table 4 (see FIG. 6).

(ID (original ID, additional ID))
In the example of the table 1 shown in FIG. 5, one print job includes two image forming conditions, and ID03 and ID04 are assigned to them, respectively. In this embodiment, IDs are generated and assigned within a finite number. In the example of the figure, it is generated in numerical order by the assigning unit 111 within the range of ID01 to ID100. In Table 1, paper size: A3 size, basis weight: 70-85 g / m ² , and paper type: "plain paper" are recorded as image formation conditions of ID03. As the image forming conditions of ID04, paper size: A4 size, basis weight: 85-90 g / m ² , and paper type: "plain paper" are recorded. When another print job is executed after that, a new ID is given to the image formation conditions if the image formation conditions are different (for example, ID 06 or later), but in the case of the same image formation conditions, the past ID is used again. , Used. In the example of FIG. 5, the description of ID01 and ID02 is omitted.

FIG. 6 is an example of a table 4 (group table) stored in the storage unit 120. In the table 4, the association between the ID (also referred to as the original ID) and the additional ID generated in association with the ID is stored as information indicating the same group. In the example of FIG. 6, the image formation condition of ID03 is A3 size, and the image formation condition of ID05 (additional ID) is A4 size after the two division processing. And it is described in the dependency relation column that ID05 is an additional ID derived from ID03. Further, in the additional ID 05, the image formation condition is described in the paper size after the first post-processing. That is, according to the print settings, the A4 size after the A3 size paper is divided into two by the two-division processing as the first post-processing is described in the paper size column of the additional ID 05. As will be described later, in the processing (conveying processing, post-processing) after the first post-processing unit, output information is collected using the additional ID 05 notified from the image forming apparatus 100.

(Notification section)
The internal communication I / F 180 functions as a notification unit, and notifies the post-processing devices (post-processing devices 300, 400, etc.) of the ID (original ID and additional ID) generated by the granting unit 111. In the following embodiment, this notification will be described as being sent each time one sheet of paper is conveyed from the image forming apparatus 100 at the timing of conveying the paper to the post-processing device in the subsequent stage. However, when paper transport under the same image formation conditions (same paper) continues, the paper is fed only when the first sheet of paper whose image formation conditions have changed is transported, and the notified information is transmitted thereafter. It may be used repeatedly.

(Collecting unit 311, 411)
The collection unit 311 of the post-processing device 300 collects output information related to paper transfer and / or post-processing from the outputs of various sensors of the post-processing device 300 such as the paper sensor 340 and the scanning scanner on the transport path. The output information for each sheet is sent from the collecting unit 311 to the second storage processing unit 312. The collection unit 411 of the aftertreatment device 400 also performs the same processing as the collection unit 311.

(2nd accumulation processing unit 312, 412)
The second storage processing unit 312 of the post-processing device 300 associates the output information sent from the collection unit 311 with the ID (original ID or additional ID) notified from the image forming device 100, and stores the storage unit 320. It is stored in Table 2 of (additional note).

In the example of Table 2 shown in FIG. 5, post-processing is executed on 50 sheets and 100 sheets of paper under the image formation conditions of ID03 and ID04 in one print job, and output information is collected and accumulated. There is. The second storage processing unit 312 stores the data of the output information associated with the ID 03 each time the paper is conveyed and processed under the image forming conditions of the ID 03. In Table 2, ID03 is composed of 50 pieces of data, but in FIG. 5, the notation of each piece of data is omitted, and only the average time data of the 50 pieces of data is shown. In the example of FIG. 5, the table 2 is temporarily stored in the storage unit 320 of the post-processing device 300, sent to the image forming device 100 at a predetermined timing, and stored in the storage unit 120 of the image forming device 100. Will be done. However, instead of temporarily storing in the storage unit 320, the second storage processing unit 312 (412) may directly store in the storage unit 120.

The second storage processing unit 412 of the post-processing device 400 also performs the same processing as the second storage processing unit 312 of the post-processing device 300. When the image forming apparatus 100 notifies the additional ID in the second storage processing unit 412, the additional ID is associated with the output information in the table 3 of the storage unit 420 (see FIG. 8B described later). To memorize. The post-processing z shown in Table 3 shows the output information when the data is discharged to the sub tray (discharge tray 492) as the discharge process.

(Printing process of image forming system 10)
Next, the printing process performed by the image forming system 10 will be described with reference to FIGS. 7 to 8C. FIG. 7 is a flowchart showing a printing process executed by the image forming system 10 according to the first embodiment. 8A to 8C are diagrams showing tables stored in each device when another print job is executed after FIG. 5.

The printing process of FIG. 7 is executed mainly by the control unit 110 of the image forming apparatus 100 and in cooperation with the control units 310 and 410 of the other post-processing devices 300 and 400.

(Image forming apparatus 100)
(Step S101)
As shown in FIG. 7, the control unit 110 of the image forming apparatus 100 receives a print job input by the user from the operation display unit 160 or an external PC through the network I / F 170. Then, the execution of the received print job is started.

(Step S102)
As described above, the granting unit 111 generates and grants an ID (identification information) for each image formation condition. Then, the first storage processing unit 112 stores (adds) this in the table 1 of the storage unit 120.

(Step S103)
The control unit 110 refers to the print setting and determines whether or not it is the first post-processing in which the paper size changes. This determination is made for each sheet of paper to be conveyed, but may be determined for each image formation condition (ID) included in the print job. If it is not the first post-processing in which the paper size changes (NO), the process proceeds to step S104, and if it is the first post-processing (YES), the process proceeds to step S105.

(Step S104)
The control unit 110 notifies the post-processing devices (post-processing devices 300 and 400) of the ID by the internal communication I / F 180 that functions as the notification unit.

(Step S105)
Here, the granting unit 111 generates an additional ID in association with the ID (original ID). Further, the association of the additional ID with the original ID is stored and managed in the table 4 of the storage unit 120 by the first storage processing unit 112.

(Step S106)
The control unit 110 notifies the post-processing devices (post-processing devices 300 and 400) of the ID and the additional ID by the internal communication I / F 180. The additional ID is notified only to the post-processing device downstream of the post-processing device (or the first post-processing unit) that performs the first post-processing that caused the additional ID to be generated.

(Step S107)
The paper feed transfer unit 130 and the image forming unit 150 of the image forming apparatus 100 convey the paper according to the print settings, form an image, and send the paper to the post-processing apparatus 300 in the subsequent stage. With the above, the processing of the image forming apparatus 100 is completed (end), and the processing from step S101 is repeated in response to accepting a new print job.

(Post-processing device 300 (post-processing device B))
(Step S301)
The paper transport unit 330 and the deformation processing unit 350 of the post-processing apparatus 300 transport the paper and perform post-processing according to the print setting.

(Step S302)
The collection unit 311 collects output information from the output of the paper sensor 340 or the like and sends it to the second storage processing unit 312.

(Step S303)
The second storage processing unit 312 stores the output information sent from the collection unit 311 in the table 2 of the storage unit 320 in association with the corresponding ID. This completes the processing of the post-processing device 300 (end).

(Post-processing device 400 (Post-processing device C))
(Step S401)
The paper transport unit 430 and the finishing unit 450 of the post-processing apparatus 400 transport the paper and perform post-processing according to the print setting.

(Step S402)
The collection unit 411 collects output information from the output of the paper sensor 440 or the like and sends it to the second storage processing unit 412.

(Step S403)
If the second storage processing unit 412 receives the notification of the additional ID from the image forming apparatus 100 (YES), the process proceeds to step S405, and if not (NO), the process proceeds to step S404.

(Step S404)
The second storage processing unit 412 stores the output information sent from the collection unit 411 in the table 3 of the storage unit 420 in association with the corresponding ID. This ID is the ID notified from the image forming apparatus 100 in step S104. FIG. 8A is a diagram showing a table stored in each device when the “next print job” is executed after FIG. FIG. 8A shows a state in which image formation and post-processing are executed on 20 sheets of paper under the same image formation conditions as ID03 as the “next print job”, and output information is accumulated. There is. That is, in the tables 2 and 3, the ID 03 is 50 in FIG. 5, whereas in FIG. 7, 20 are added and the output information of 70 (70) is stored. In this case, since the image formation conditions are the same as those of the past ID 03, a new ID is not generated and the ID 03 used in the past is assigned.

(Step S405)
The second storage processing unit 412 stores the output information sent from the collection unit 411 in the table 3 of the storage unit 420 in association with the additional ID. This additional ID (for example, ID 05) is the additional ID notified in step S106. FIG. 8B is a diagram showing a table stored in each device when the next print job is executed after FIG. 5. In FIG. 8B, as the next print job after FIG. 5, the image formation and the post-processing apparatus 300 (post-processing apparatus B) are used for 20 sheets of A3 size paper under the image formation condition of the print setting of ID03. It shows the state in which post-processing is executed and output information is accumulated. Further, since the deformation processing unit 350 (first post-processing unit) of the post-processing device 300 performed the two-division processing, the post-processing device 400 (post-processing device C) in the subsequent stage has 40 sheets, which is a multiple of the A4 size. Paper is transported. Since the post-processing device 400 has executed post-processing on the 40 sheets of paper, the output information of 40 sheets (40 sheets) is stored in the table 3 of FIG. 8B in association with the additional ID 05. This completes the processing of the post-processing device 400 (end).

(effect)
As described above, in the present embodiment, the image forming apparatus and the post-processing apparatus can appropriately collect the output information by collecting the output information regarding the output result of the paper by using the same ID. In particular, the second storage processing unit is generated in association with the output information and the identification information when the type of post-processing executed by the post-processing device is the predetermined first post-processing that changes the shape of the paper. The output information can be appropriately collected by associating it with the additional identification information and storing it in the storage unit.

As a comparative example, FIG. 8C is a diagram showing a table stored in each apparatus when the same print job as in FIG. 8B is executed as the next print job. In the comparative example, a case is shown in which the original ID is continuously used without assigning an additional ID even though the first post-processing for changing the shape of the paper is executed. In this case, in the table 3 of FIG. 8C (enclosed by the broken line in the table 3), up to 50 sheets (see the table 3 of FIG. Output information was accumulated. In the subsequent 40 sheets (40 sheets obtained by dividing 20 sheets of A3 size into two), output information of A4 size is accumulated regardless of the ID of A3 size. In this case, output information of 50 sheets of A3 size and 40 sheets of A4 size, 90 sheets in total (90 sheets) is stored. In this way, the output information of different image formation conditions is aggregated and aggregated under the same ID. That is, although the post-processing device C collects the output information of the A4 size paper, it is collected and stored as the A3 size of the ID 03 as the storage process. Therefore, when analyzing the data, the ID 03 includes data that has a meaningless adverse effect. In Table 3 of FIG. 8C in the comparative example, as compared with Table 3 of FIG. 8B in the example, the aggregated result of ID03 shows that the average time and the variance are far from the original numerical values (A3 size), and the reliability is impaired. Data is collected. Therefore, when such data is collected and analyzed by the management server 90 as described later, the analysis result may be adversely affected. In this respect, in the present embodiment, in the case of the first post-processing that changes the shape of the paper, the output information and the additional identification information generated in association with the identification information are associated and stored in the storage unit. Therefore, such a problem does not occur.

(Sending output information to the management server 90)
FIG. 9 is a flowchart showing a process of transmitting output information to the management server 90 and resetting the ID in the image forming system in the modified example.

(Step S501)
When the predetermined timing is reached (YES), the control unit 110 of the image forming apparatus 100 advances the process to step S501. For example, the predetermined timing is every 24 hours or the timing when the predetermined time is reached. When a finite number of IDs are used, the predetermined timing is preferably set at a timing so that the IDs are not exhausted. Alternatively, when a finite number of IDs are about to be exhausted, it may be determined that a predetermined timing has been reached as a trigger and the circumstances.

(Step S502)
The control unit 110 of the image forming apparatus 100 makes a transmission request to the post-processing apparatus 200, 300, 400, and obtains data in response. Then, each table (a table in which the output information of the tables 2, 3 and the like is associated with the ID (original ID, additional ID)) stored in the storage units 220, 320, 420 of each device is aggregated. The aggregated table is temporarily stored in the storage unit 120, and the data of each table stored in the storage units 220, 320, 420 of the post-processing devices 200, 300, 400 of the aggregation source is erased. May be good.

(Step S503)
The control unit 110 adds (1) unique unique information of the image forming apparatus 100 or the image forming system 10, for example, the apparatus S / N (serial number) and / or (2) the current date and time information to each ID. To do. For example, in the case of ID002, a 5-digit S / N and an 8-digit date are added after the ID. As a result, even if the ID is finite, the management server 90 can be identified without duplicating the ID with the ID sent last time. It can also be identified as information sent from other image forming systems.

(Step S504)
The control unit 110 of the image forming apparatus 100 tells the management server 90 by the network I / F 170 that functions as a transmitting unit that the information of the combination of the image forming condition, the ID, and the output information, or the image forming condition, the additional ID, And the information of the combination of the output information (hereinafter, the information of these combinations is simply referred to as "combination information") is transmitted to the management server 90. Specifically, the image forming apparatus 100 transmits each aggregated table and a group table (table 4) in which the ID and the additional ID are associated with each other to the management server 90.

(Step S505)
After receiving the receipt confirmation command from the management server 90, the control unit 110 deletes each table using the ID in the image forming system 10. It also resets the ID. After the reset, the granting unit 111 of the control unit 110 can reuse a finite number of IDs. Specifically, the assigning unit 111 generates IDs in order from ID 01 and assigns them to each image forming condition.

In this way, the image forming system 10 transmits the accumulated combination information to the management server 90, and the management server 90 side predicts the failure of the source image forming system 10 and consumables from the received information. It is possible to accurately predict the replacement time of the server. Further, on the image forming system 10 side, by resetting the IDs after transmitting the combination information, even when a finite number of IDs are used, the IDs are not exhausted.

(Second embodiment)
FIG. 10 is a flowchart showing a printing process executed by the image forming system according to the second embodiment. In the first embodiment, when the print setting is such that the first post-processing for changing the shape of the paper is performed, an additional ID is generated, and the additional ID and the output information are associated with each other to store the storage unit. It was stored in 120, 420, etc. In the second embodiment, the number of samples is reduced, but even when the first post-processing is performed, the output information is deleted without being stored in the storage unit without generating an additional ID.

(Step S314)
The control unit 310 of the post-processing apparatus 300 refers to the print setting and determines whether or not the first post-processing changes the paper size. If it is not the first post-processing in which the paper size changes (NO), the processing ends (end). On the other hand, if it is the first post-processing in which the paper size changes (YES), the process proceeds to step S315.

(Step S315)
The post-processing device 300 transmits a signal indicating that there is a size change to the post-processing device 400 (post-processing device C) in the subsequent stage by the internal communication I / F 380 that functions as a notification unit.

(Step S413)
If the second storage processing unit 412 receives a notification from the post-processing device 300 having the first post-processing unit that there is a size change (YES), the process proceeds to step S415, and if not, the process proceeds to step S415 (NO). , The process proceeds to step S414.

(Step S414)

(Step S415)
The second storage processing unit deletes the output information sent from the collection unit 411 and does not store the output information in the storage unit 420. This completes all processing (end).

As described above, in the second embodiment, the output information regarding the paper on which the first post-processing has been performed is not stored in the storage unit. By doing so, the same effect as that of the first embodiment can be obtained. That is, it is possible to prevent the data whose reliability is impaired from being collected without collecting the output information of different paper sizes that do not meet the image formation conditions.

(Third Embodiment)
FIG. 11 is a flowchart showing a printing process executed by the image forming system according to the third embodiment. In the first embodiment, when the print setting is such that the first post-processing for changing the shape of the paper is performed, the image forming apparatus 100 automatically generates an additional ID, and the additional ID and the output are output.

(Step S325)
When the post-processing device 300 determines in step S324 that the execution instruction of the first post-processing has been received, the post-processing device 300 transmits a request for assigning an additional ID to the image forming device 100 by the internal communication I / F 380 that functions as a notification unit. To do. As the grant request, a signal indicating that the size has been changed may be simply used as the grant request.

(Image forming apparatus 100)

(Step S129)
The control unit 110 uses the internal communication I / F 180 functioning as a notification unit to transmit the additional ID to the post-processing device 400 (post-processing) on the downstream side of the post-processing device (or the first post-processing unit) that performs the first post-processing.
