DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0010] [Overview of Image Forming Apparatus] As shown in FIGS. 1 and 2, an image forming apparatus 1 according to this embodiment includes a main body 10, a relay unit RU, a post-processing device 20 serving as a paper transport device, and a finisher FS.

[0011] The main body 10 forms a color image by electrophotography based on image data obtained by reading an image from a document or image data received from an external device. The paper on which the image has been formed is discharged to a relay unit RU by a paper discharge roller R1. As shown in Figures 1 and 2, the main body 10 is configured to include an operation unit 11, a display unit 12, a document reading unit 13, an image forming unit 14, a paper feeding unit 15, an image forming control unit 16, a memory unit 17, a controller IF (Interface) 18, and an image processing unit 19.

[0012] The operation unit 11 includes a touch panel formed to cover the display screen of the display unit 12, and various operation buttons such as numeric buttons and a start button, and outputs an operation signal to the image formation control unit 16 based on a user's operation.

[0013] The display unit 12 is configured with an LCD (Liquid Crystal Display), and displays various screens according to instructions of a display signal input from the image formation control unit 16 .

[0014] The document reading unit 13 includes an ADF (automatic document feeder), a scanner, and the like, and outputs image data obtained by reading an image of a document to the image formation control unit 16.

[0015] The image forming unit 14 forms an image on a sheet of paper supplied from a paper feed unit 15 based on image data that has been image-processed by an image processing unit 19 . The image forming unit 14 is configured with photosensitive drums 141Y, 141M, 141C, and 141K corresponding to each of the colors yellow (Y), magenta (M), cyan (C), and black (K), an intermediate transfer belt 142, a secondary transfer roller 143, a fixing unit 144, etc.

[0016] After being uniformly charged, the photoconductor drum 141Y is scanned and exposed to a laser beam based on yellow image data to form an electrostatic latent image. Then, yellow toner is attached to the electrostatic latent image on the photoconductor drum 141Y, and development is performed. The photoconductor drums 141M, 141C, and 141K are similar to the photoconductor drum 141Y except for the colors they handle, and therefore descriptions thereof will be omitted.

[0017] The toner images of each color formed on the photoconductor drums 141Y, 141M, 141C, and 141K are successively transferred (primary transfer) onto the rotating intermediate transfer belt 142. That is, a color toner image is formed on the intermediate transfer belt 142 in which the toner images of four colors are superimposed. The color toner image on the intermediate transfer belt 142 is transferred all at once onto a sheet of paper by a secondary transfer roller 143 (secondary transfer).

[0018] Fixing section 144 includes a heating roller that heats the paper onto which the color toner image has been transferred, and a pressure roller that presses the paper, and fixes the color toner image onto the paper by applying heat and pressure.

[0019] The paper feed unit 15 includes paper feed trays T11 to T13, and supplies paper to the image forming unit 14. Each of the paper feed trays T11 to T13 stores paper of a paper type and size that are predetermined for that paper feed tray.

[0020] The image formation control unit 16 includes a CPU, a ROM, and a memory. The CPU reads out various processing programs (including an adjustment program for the post-processing device; the same applies below) stored in the ROM, and performs centralized control of the operations of each part of the main body 10 according to the programs. When post-processing is to be performed on output paper, the CPU issues an instruction to the post-processing device 20 to execute a predetermined post-processing. The ROM is composed of non-volatile semiconductor memory or the like, and stores various processing programs, parameters and files required for executing the programs, etc. The memory is configured with a dynamic random access memory (DRAM) or the like, and temporarily stores various data such as programs and image data related to various image processes.

[0021] The storage unit 17 is a non-volatile storage device such as a HDD (Hard Disk Drive) or a semiconductor memory that stores various data such as programs and image data. The storage unit 17 stores data such as program data and various setting data in a manner that allows the image formation control unit 16 to read and write the data.

[0022] The controller IF 18 receives image data input from an external device.

[0023] The image processing unit 19 performs necessary image processing on the image data stored in the storage unit 17, the image data obtained by reading an image from an original by the original reading unit 13, and the image data input from an external device, and transmits the image data after image processing to the image forming unit 14. Image processing includes gradation processing, halftone processing, color conversion processing, etc. Gradation processing is a process of converting the gradation value of each pixel of the image data into a corrected gradation value so that the density characteristics of the image formed on the paper match the target density characteristics. Halftone processing is an error diffusion process, a screen process using an ordered dither method, etc. Color conversion processing is a process of converting each RGB gradation value into each CMYK gradation value.

[0024] The relay unit RU is installed between the main body 10 and the post-processing device 20, and has a function of synchronizing with the transport speed of the paper transported from the main body 10.

[0025] The post-processing device 20 is a device that performs post-processing as necessary on the paper discharged from the relay unit RU. Examples of post-processing include slittering, gutter slittering, CD cutting, crease processing (upper convex or lower convex), FD / CD perforation, etc. Post-processing is not essential, and the post-processing device 20 performs it only when instructed to do so by the main body 10. If post-processing is not required, the post-processing device 20 transports the transported paper directly to the finisher FS.

[0026] As shown in Figures 1 and 2, the post-processing device 20 is configured to include a conveying section 21, post-processing modules M1 to M4, a purge tray 25 that stacks sheets to be purged from the post-processing device 20, and a post-processing control section 26.

[0027] The transport section 21 transports the paper transported from the relay unit RU to the post-processing modules M1 to M4, and transports the paper that has been post-processed in the post-processing modules M1 to M4 to various trays (including the purge tray 25) or the finisher FS.

[0028] The post-processing modules M1 to M4 perform post-processing on the conveyed paper. The post-processing device 20 can be installed arbitrarily by selecting a post-processing module according to the post-processing to be performed on the image output formed by the image forming unit 14. The control unit (16, 26) recognizes the type of post-processing device installed in the installation unit (hereinafter referred to as "slot" and the same reference numerals as the modules) of each of the post-processing modules M1 to M4. For example, a slitter is installed as the most upstream post-processing module M1, a downward convex creaser for performing a crease process to make downward convex creases on paper is installed as the post-processing module M2, and a gutter slitter for cutting (gutter cutting) paper at the center in the CD direction (paper width direction Y) is installed as the post-processing module M3. The control unit (16, 26) recognizes the type and installation position of the multiple installed post-processing modules (in the above case, slot M1 is a slitter, slot M2 is a downward convex creaser, and slot M3 is a gutter slitter). The most downstream post-processing module M4 is a fixed CD cutter that cuts the paper in the CD direction (paper width direction Y). Post-processing modules selected arbitrarily are installed in the slots M1 to M3. In addition to the above, post-processing modules include an upward convex creaser for creating upward convex creases on paper, an FD perforation machine for perforating paper in the FD direction (paper transport direction X), and a CD perforation machine for perforating paper in the CD direction (paper width direction Y).

[0029] [Adjustment of post-treatment device] The post-processing device adjustment method according to the present embodiment is realized by the post-processing device adjustment program and hardware. The adjustments in the post-processing device 20 include the following adjustment items. -Post-processing stop position offset adjustment Tilt adjustment (paper transport skew correction: by steering timing) -CD cutting position correction (depending on cutting timing) -Slit position correction on both ends (curvature correction, FD direction position correction) -Gutter cut slit position correction (curve correction, FD direction position correction, groove cut interval correction) - Crease position correction (curve correction, timing position correction) -FD perforation position correction (curve correction, FD direction position correction) CD perforation position correction (curvature correction, timing position correction)

[0030] When the control unit (16, 26) determines that a post-processing module has been replaced by a user in the post-processing device 20 based on the recognition of the types and installation positions of the multiple post-processing modules, it determines the necessary adjustment items and the adjustment order according to the type, configuration and installation positions of the installed post-processing modules. The control unit (16, 26) also determines at least one of whether guidance is required, the guidance method and the guidance content. Note that even if the combination of post-processing modules is the same, the adjustment items may change if the installation positions are different.

[0031] The control unit (16, 26) determines and executes the adjustment items required for each module based on the combination and installation position of the post-treatment modules, thereby making it possible to prevent problems due to missed adjustments. Furthermore, even if an adjusted module is combined with another module, it may become necessary to adjust it again. In this case, the control unit (16, 26) determines and executes the newly required adjustment items, thereby preventing problems due to missed adjustments.

[0032] After the control unit (16, 26) determines the necessary adjustment items, the adjustment order, the guidance contents, etc., it displays the necessary adjustment items on the display unit 12 in the adjustment order, and provides guidance on the adjustment method so that the user can make the necessary adjustments. For example, if the control unit (16, 26) recognizes that the types and installation positions of the multiple post-treatment modules after replacement are as follows: slot M1: slitter, slot M2: convex creaser, and slot M3: gutter slitter, the control unit (16, 26) displays an adjustment menu screen 121 including adjustment items on the display unit 12 as shown in FIG. 3, and guides the user on how to make adjustments.

[0033] (Professional Adjustment) 3, when "Professional Adjustment" is selected by a user operation, the control unit (16, 26) causes the image forming unit 14 to print on paper an adjustment chart suitable for this professional adjustment based on the above recognition. In other words, the control unit (16, 26) includes, in the adjustment content determined based on the above recognition, an image output of an adjustment chart corresponding to a combination of multiple post-processing modules of the recognition, and controls the execution of this. Next, the control unit (16, 26) causes the post-processing device 20 to receive the output paper of the adjustment chart from the image forming unit 14 and perform the necessary post-processing in each of the modules M1-M4. Here, the post-processing is performed using the existing adjustment values.

[0034] The user refers to the adjustment chart paper on which the post-processing has been performed as described above, checks the quality of the post-processing, and performs necessary adjustments by operating the operation unit 11, etc. A specific example of the operation is as follows. Fig. 4 shows an example of a guidance display for professional adjustment. The user looks at the adjustment chart, selects the item that needs adjustment, and performs the adjustment. For example, if the FD direction position of the slit position correction at both ends needs to be adjusted, the user selects "FD direction position" under the item "Slit position correction at both ends" in Fig. 4. In response to the selection, the control unit (16, 26) pops up an adjustment operation panel screen 122, for example, as shown in Fig. 5, to enable the user to change the adjustment value by operation.

[0035] The control unit (16, 26) checks items for which adjustment has been completed as shown in Fig. 4, and controls the display so that it can be seen on the adjustment menu screen 121. Furthermore, if there are items that do not require adjustment, the control unit (16, 26) controls the display so that a check mark can be placed on the items by the user pressing a square. When all adjustment items are marked with a check mark, all adjustments have been completed.

[0036] (Easy adjustment) The easy adjustment feature uses semi-automatic adjustment, providing guidance to make adjustments easily even for inexperienced users. 3, when "easy adjustment" is selected by a user operation, the control unit (16, 26) causes the image forming unit 14 to print on paper an adjustment chart suitable for this simple adjustment based on the above recognition. In other words, the control unit (16, 26) includes, in the adjustment content determined based on the above recognition, an image output of an adjustment chart corresponding to a combination of multiple post-processing modules of the recognition, and controls the execution of this. Next, the control unit (16, 26) causes the post-processing device 20 to receive the output paper of the adjustment chart from the image forming unit 14 and perform the necessary post-processing in each of the modules M1-M4. Here, the post-processing is performed using the existing adjustment values.

[0037] FIG. 6 shows an example of a guidance display for simple adjustment. The control unit (16, 26) controls the display of a guidance screen 123 as shown in Fig. 6, and prompts the user to read the post-processed adjustment chart with the scanner (12) of the image forming device. When the scan start button 123a is pressed, the control unit (16, 26) causes the document reading unit 13 to execute a scan, and based on the scanned image that has been read, judges the quality of the post-processing and performs any necessary corrections. In other words, the control unit (16, 26) causes the output object on which the adjustment chart has been imaged to be post-processed with the existing adjustment values, and then determines and controls the execution of further adjustment contents according to the image of the output object read by the scanner. At that time, when a user operation is required, such as bending correction of a post-processing module, the control unit (16, 26) displays it on the display unit 12 so that the user can perform the appropriate correction work. For example, when a user operation is required to correct bending of a creaser installed in the slot M2, a guidance screen 124 such as "Please turn the bending correction knob (M2a shown in Fig. 8-10) of the slot M2 (module 2) to the right by three registers" is displayed on the display unit 12 as shown in Fig. 7 to guide the correction work. In this way, when the adjustment contents determined according to the image read by the scanner include mechanical adjustment items by user operation, the control unit (16, 26) executes and controls guidance of the adjustment method and adjustment value to the user, including the adjustment contents.

[0038] Furthermore, the control unit (16, 26) automatically corrects the control values ​​of the post-processing module managed by the control unit (16, 26) among the adjustment contents determined according to the image read by the scanner, for example, the FD direction position correction among the correction of the slit positions at both ends.

[0039] Once a full set of corrections has been made by the above professional or simple adjustments, adjustment chart output → post-processing → (image reading →) confirmation of results can be repeated as necessary to perform adjustment work until the required post-processing accuracy is achieved. The control unit (16, 26) provides guidance for readjustment via the display unit 12 (not shown).

[0040] (Adjustments vary depending on the combination) The control unit (16, 26) may vary the adjustment content of at least one of the post-processing modules depending on the combination of the post-processing modules. The adjustment items for each module may differ depending on the combination of the modules. For example, when considering adjustment items for the CD perforation, which is one of the post-processing modules, basically, two adjustments are required: adjusting the curvature of the module and adjusting the timing of CD perforation from the leading edge of the paper. However, if the CD perforation and creaser are installed at the same time, and taking into account the fluctuation in paper length after creasing by the creaser, it is necessary to adjust the timing of CD perforation twice, once before creasing (uncreased) and once after creasing (creased). On the other hand, when a creaser is not installed (when a creaser is not combined), the timing adjustment for performing the CD perforation process of the CD perforation machine may be performed in one way under the condition before the crease process (when the crease process is not performed). In this way, the adjustment contents of the CD perforation, which is one post-processing module, may be made different depending on the other post-processing modules that are combined with it (the combination including the CD perforation is different). As described above, by varying the adjustment content according to the conditions of the combination, it is possible to execute appropriate adjustment according to the conditions of the combination even with the same post-processing module.

[0041] (Additional explanation about adjustment chart) The control unit (16, 26) includes in the adjustment contents the image output of an adjustment chart according to a combination of multiple post-processing modules. Since the adjustment items for each module differ depending on the combination of post-processing modules, the adjustment sheets for adjustment also differ. A specific example is shown below. 11 and 12 show a sheet S and adjustment charts C1 and C2 outputted thereon. A cross-sectional view of the sheet S is also shown in FIG. The adjustment chart C1 in Fig. 11 is an adjustment chart in the case where the slot M1 is a slitter, the slot M2 is an FD sewing machine, and the slot M3 is a CD sewing machine. The adjustment chart C2 in Fig. 12 is an adjustment chart in the case where the slot M1 is a slitter, the slot M2 is a creaser, and the slot M3 is a CD sewing machine. Adjustment chart C1 in Fig. 11 includes reference lines C11 and C12 for FD perforations and reference line C13 for CD perforations. Adjustment chart C2 in Fig. 12 includes reference line C21 for CD perforations in uncreased condition, crease reference line C22, and reference line C23 for CD perforations in creased condition. R11-13 and R21-23 are examples of actual processing positions, which may or may not match the reference lines. In this way, the only difference is whether the post-processing module M2 is a creaser or an FD sewing machine, but since the adjustment items required for each are different, the control unit (16, 26) determines an adjustment chart suitable for adjustment.

[0042] Furthermore, the control unit (16, 26) causes the adjustment content to include image output of an adjustment chart corresponding to the installation position of each of the plurality of post-processing modules. Specific examples are shown below. Consider the case where the creaser and CD perforation are installed in the reversed positions compared to the case in Figure 12 (Figure 13). Adjustment chart C3 in Figure 13 is an adjustment chart for the case where slot M1 is the slitter, slot M2 is the CD perforation, and slot M3 is the creaser. Adjustment chart C2 in Figure 13 includes reference line C31 of the CD perforations when the creases are not processed, crease reference line C32, and reference line C33 of the CD perforations when the creases are processed. R31-33 are examples of actual processing positions, which may or may not match the reference lines. CD perforation (R33) under crease processing conditions with the reference line C33 as the target is performed after the crease processing. At this time, assuming that the paper is not fed backward, after the crease processing, the processing target position of the CD perforation (M2) is separated backward (in the negative direction of the X coordinate) by the module distance MD2 from the crease position (M3, R32). The module distance MD2 between the module M2 and the module M3 is also shown in Figure 1. Therefore, the distance in the conveying direction X between the crease reference line C32 and the CD perforation reference line C33 under creased conditions must be wider than the module interval MD2. In the case of Figure 12, this does not happen because the paper can be sent from the processing position of the creaser (M2) and placed in the processing position of the CD perforation (M3). As described above, for example, even if the combination of multiple post-processing modules is the same, the control unit (16, 26) determines an appropriate adjustment chart according to the installation position.

[0043] [Summary of effects, etc.] According to the above embodiment, in the post-processing device 20, which can be installed arbitrarily by selecting a post-processing module M1-M3 according to the post-processing to be performed on the image output product S, the post-processing device configuration can be efficiently and appropriately adjusted by the selection and installation.

[0044] In the above embodiment, the number of post-processing modules that can be installed at will is three, but the present invention is not limited to this, and the number of post-processing modules that can be installed at will may be two or four or more. Furthermore, the types of post-processing modules are not limited to those listed above, and various other processing modules may be applied. Adjustments are also performed after replacing modules of the same type. This is because adjustments are necessary due to individual differences even within the same type. Therefore, adjustments are performed even if the combination or installation position is not necessarily different after replacing the modules. The adjustment may be performed without replacing the module, since adjustment may become necessary due to changes over time. The adjustment may be performed at any time, at the discretion of the control unit or at the request of the user.

[0045] In addition, the detailed configurations and operations of each device constituting the image forming apparatus may be modified as appropriate without departing from the spirit and scope of the present invention. [Explanation of symbols]
