[0010] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings.

[0011] <First embodiment> FIG. 1 is a block diagram showing the hardware configuration of an MFP1 (Multi-Function Peripheral) which is an example of an image forming apparatus according to this embodiment.

[0012] 1, the MFP 1 includes a controller 101, a scanner 102, a printer 103, a finisher 104, a network interface (I / F) 105, an operation unit 106, etc. The MFP 1 is connected to a computer terminal 107 via a network.

[0013] The MFP1 has a printing function, a copying function, a transmission function, a post-processing function, etc. The printing function is a function that analyzes PDL (page description language) data received from a computer terminal 107 and prints it on a medium such as paper (hereinafter referred to as paper) using a printer 103. The copying function is a function that prints image data read by scanning an original using a scanner 102 on paper. The transmission function is a function that transmits image data read by scanning an original to the computer terminal 107 via a network. The post-processing function is a function that performs post-processing using a finisher 104 on paper on which printing has been performed using the printing function.

[0014] The computer terminal 107 is an information terminal equipped with a communication function, such as a PC (personal computer), a server device, a smartphone, a tablet terminal, etc. The number of computer terminals 107 connected to the MFP 1 may be multiple.

[0015] The network I / F 105 is a communication control circuit and a communication port that mediate a communication connection with a network such as a LAN, a WAN, the Internet, etc. The controller 101 transmits and receives data to and from a computer terminal 107 that is communicatively connected via the network I / F 105.

[0016] Operation unit 106 has hard keys for inputting various settings and instructions to MFP 1, and a display for displaying the processing status and various information. The hard keys include a copy button, a cancel button, a reset button, a numeric keypad, etc. The display is configured by an LCD display, an organic EL display, etc. Operation unit 106 may be a touch panel display in which a touch panel is integrally provided with the display, and various settings and instructions may be received via the display.

[0017] An operation unit of computer terminal 107 connected via network I / F 105 may be used in the same manner as operation unit 106 of controller 101. For example, controller 101 of MFP1 causes a display unit of computer terminal 107 to display information output from controller 101. Also, a configuration may be adopted in which controller 101 of MFP1 acquires an instruction input by a user to an input unit of computer terminal 107.

[0018] The controller 101 is a main control unit of the MFP 1 and controls each unit, namely, the scanner 102, the printer 103, the finisher 104, and the operation unit 104 in an integrated manner.

[0019] FIG. 2 is a block diagram showing the internal configuration of the controller 101. The controller 101 includes a CPU 201, a RAM 202, a ROM 203, a storage unit 204, a communication unit 205, an operation unit I / F 206, a printer I / F 207, a scanner I / F 208, and a finisher I / F 209, and each unit is connected by a bus 210.

[0020] The CPU 201 loads a program stored in the storage unit 204 or the ROM 203 into a work area of ​​the RAM 202 and executes it. The ROM 203 has a read-only nonvolatile storage area and a rewritable storage area such as a flash ROM. The nonvolatile storage area permanently holds programs such as the boot program and BIOS of the MFP1, data, etc. The ROM 203 also records the programs executed by the CPU 201 and various programs for operating the MFP1.

[0021] The RAM 202 is composed of a non-volatile memory such as FRAM (registered trademark) capable of retaining stored contents, and a volatile memory such as DRAM from which stored contents are erased when the power is turned off. The RAM 202 temporarily retains programs loaded from the ROM 203, the storage unit 204, etc., and also has a work area used by the CPU 101 to perform various processes described later. The RAM 202 temporarily stores various data in the volatile memory, and stores various setting data in the non-volatile memory.

[0022] The storage unit 204 is configured with an HDD, an SSD, a flash memory, etc., and stores various programs and data. The storage unit 204 may be detachable from the MFP 1, or may be built into the MFP 1. Note that the programs executed by the CPU 201 may be downloaded from another MFP or computer terminal 107 via the network I / F 105 and stored in the storage unit 204.

[0023] Moreover, the functions of the RAM 202 and the ROM 203 may be taken over by the storage unit 204 .

[0024] The communication unit 205 is a communication port and communication control circuit of the above-mentioned network I / F 105. In addition to Ethernet and TCP / IP, it may include short-range wireless communication such as Bluetooth (registered trademark), infrared, and NFC. The communication may be either wired or wireless.

[0025] The operation unit I / F 206 is an interface that connects the display, hard keys, touch panel, etc. of the operation unit 106 to the controller 101. The CPU 201 transmits display data to the operation unit 106 via the operation unit I / F 206 and displays the data on the display. The CPU 201 also acquires data input to the hard keys or touch panel of the operation unit 106 via the operation unit I / F 206.

[0026] The printer I / F 207, scanner I / F 208, and finisher I / F 209 are interfaces that respectively connect the printer 103, scanner 102, and finisher 104 to the CPU 201. The CPU 201 transmits control signals, image data, and the like to the printer 103, scanner 102, and finisher 104 via the printer I / F 207, scanner I / F 208, and finisher I / F 209, respectively. The CPU 201 obtains status-related information, image data, and the like from the printer 103, scanner 102, and finisher 104.

[0027] Image data read by the scanner 102 or image data input from the computer terminal 107 to the MFP 1 via the network I / F 105 can be stored in the RAM 202 or storage unit 204 in the controller 101 .

[0028] It is also possible to store image data in advance in a removable memory (such as a USB memory or a memory card) and import the image data from that memory.

[0029] The printer 103, finisher 104, and scanner 102 may each exist as a standalone peripheral device on a network, rather than inside the MFP. In that case, the printer 103, finisher 104, and scanner 102 are each connected to the controller 101 of the MFP1 via the network I / F 105. The controller 101 of the MFP1 may control the printer 103, finisher 104, and scanner 102, respectively.

[0030] The scanner 102 performs a scanning operation in accordance with a control signal input from the controller 101. The scanner 102 has a feeder that automatically supplies a document to be scanned, and a scanning unit that optically reads an image on the document and converts it into image data in a digital format. The image data read by the scanning operation is sent to the CPU 201 of the controller 101 via the scanner I / F 208 and stored in the RAM 202 or the storage unit 204.

[0031] Printer 103 performs printing operations according to control signals input from controller 101. Printer 103 forms an image on paper based on image data for printing input from CPU 201, and ejects the paper. Paper is fed from a paper feed unit. Printer 103 may be a laser beam printer that uses toner as a coloring material and forms and outputs an image on paper by an electrophotographic method, or may form an image by an inkjet method that uses ink as a coloring material, or by some other method.

[0032] The printer 103 has a paper discharge unit for discharging printed paper. The paper discharge unit is connected to a finisher 104.

[0033] The finisher 104 is a device that performs post-processing such as stapling (binding), punching, and folding on the printed matter discharged from the paper discharge unit of the printer 103. The finisher 104 may perform these processes alone or in combination.

[0034] For example, a post-processing called saddle stitching is a post-processing in which the paper discharged from the printer 103 is folded in half at a predetermined folding position (a position that divides the long side of the paper into approximately two equal parts) and stapled (stapling) at the folding position. Punching is a post-processing in which punch holes are formed at predetermined positions in the paper to be used when filing the paper. The configuration and operation of the finisher 104 will be described later.

[0035] The positions where the finisher 104 performs these post-processing processes (folding position, binding position, punching position) are preset as reference positions according to the paper size, and are stored as setting information in the RAM 202, ROM 203, or storage unit 204. Information on paper that can be used for each type of post-processing is also stored as setting information. For example, in the case of the above-mentioned saddle stitching, information that A3R and A4R paper can be used. The position where the post-processing is performed can be adjusted by the user. Adjusting the position of the post-processing will be described in detail later.

[0036] Folding is a process in which paper is folded in one or more fold positions. Examples include folding in two, folding in three (Z-fold, C-fold), and folding in four. Stapling is a process in which paper is stapled to bind. Punching is a post-processing process that forms punch holes used when filing paper, and can be two-hole, four-hole, etc. Saddle stitching is a post-processing process that combines folding and stapling, in which paper is folded down the center and stapled down the center to bind the paper.

[0037] Fig. 3 is a diagram showing a stapling mechanism and a folding mechanism of the finisher 104. As shown in Fig. 3, the finisher 104 is provided with a stapler 301a, an anvil 301b, a pair of folding rollers 303a and 303b, a thrusting member 302, a positioning member 305, a tray 306 for stacking sheets of paper to form a sheet bundle P, and the like.

[0038] The stapler 301a is driven by a stapler motor, and cooperates with the anvil 301b to staple the stack of sheets P. The stapler motor is controlled by the CPU 201.

[0039] The positioning member 305 is movable and is raised and lowered along the tray 306 by a positioning motor. The positioning member 305 transports the sheet stack P on the tray 306 to the respective reference positions of the folding position or the binding position, or to an adjusted position. The positioning motor is controlled by the CPU 201.

[0040] The pushing member 302 is provided at a position facing the pair of folding rollers 303a, 303b across the stack of paper P. The pushing member 302 is driven by a pushing motor, and performs a pushing operation on the stack of paper P. The pushing motor is controlled by the CPU 201. By the pushing operation, the stack of paper P is pushed between the pair of folding rollers 303a, 303b and folded.

[0041] When saddle-stitching is performed by the finisher 104, the stack of sheets P discharged from the sheet discharge port of the printer 103 is carried into a tray 306 in the finisher 104. As shown in FIG. 3(a), the stapler 301a and the anvil 301b work together to perform stapling on the sheets P carried into the tray 306. At this time, the positioning member 305 has been moved to a standard stapling position. The standard stapling position is a distance that is half the length (2Y) of the stack of sheets P in the transport direction. When the stapling is completed, the stack of sheets P is stapled.

[0042] 3(b), positioning member 305 is moved to the reference folding position, and pushing member 302 is disposed to face the staple position of stack of paper P. The movement distance is the distance from the staple position of stapler 301a to the space between folding rollers 303a, 303b. In this state, pushing member 302 is protruded toward stack of paper P, and stack of paper P is pushed into the space between folding rollers 303a, 303b. This operation causes the saddle-stitched printed matter, folded in two at the stapled position, to be discharged.

[0043] Next, the functional configuration of the MFP 1 will be described. Fig. 4 is a diagram showing the functional configuration of the MFP 1. Fig. 4 shows functional units related to adjustment of the post-processing position. These functional units may be realized as a program module configuration. The program is stored in the storage unit 204 or ROM 203, and the CPU reads and executes the program from the storage unit 204 or ROM 203 to realize each function in Fig. 4.

[0044] As shown in FIG. 4, the controller 101 of the MFP 1 includes a post-processing control unit 401, a chart output unit 402, a display control unit 403, an adjustment setting unit 404, an adjustment control unit 405, and the like.

[0045] The post-processing control unit 401 controls the execution of post-processing by the finisher 104. The post-processing control unit 401 drives and controls each unit of the finisher 104 according to instructions input by a user via the operation unit 106. Post-processing such as folding, stapling, and punching is performed on printed paper discharged from the printer 103.

[0046] The chart output unit 402 uses the printer 103 and the finisher 104 to print and post-process an image for a test chart on paper, and outputs it as a test chart 500. The test chart 500 is used when the user measures the position where post-processing is performed (hereinafter referred to as the post-processing position) in the adjustment setting of the post-processing position. Note that if the user sets the test chart 500 not to be output, the chart output unit 402 does not output the test chart 500.

[0047] Fig. 5 is a diagram showing an example of a test chart 500 for saddle stitch adjustment. As shown in Fig. 5, the test chart 500 has prints 501 and 502 that enable the left-right and top-bottom orientation of the paper to be determined (recognized). In the example of Fig. 5, "A" 501 is printed on the right side of the paper, and "B" 502 is printed on the left side of the paper. The test chart 500 is actually saddle stitched by the finisher 104, and staples 503, 503 and a folding position 504 are formed. The test chart 500 is output in a paper size specified by the user.

[0048] The prints 501 and 502 on the test chart 500 allow the user to easily distinguish the print surface and paper orientation of the test chart 500. Note that the prints on the test chart 500 are not limited to alphabets such as "A" and "B." Other letters, marks, figures, or patterns that can be distinguished from top, bottom, left, and right, or combinations of these may also be used.

[0049] 5 is an example, and the chart output unit 402 outputs a test chart corresponding to the type of post-processing specified by the user. For example, it is possible to output a test chart corresponding to each post-processing, such as center folding, Z-folding, C-folding, stapling, punching, Z-folding and stapling, Z-folding and punching, center folding and punching, etc. Printing data required for outputting the test chart 500, setting information for post-processing, paper information, etc. are stored in advance in the RAM 202, ROM 203, or storage unit 204.

[0050] The display control unit 403 causes the operation unit 106 to display a schematic diagram showing the test chart 500 in a three-dimensional manner (hereinafter referred to as a three-dimensional diagram) and adjustment setting screens 900, 930 (FIG. 9) showing measurement points (measurement positions) on the test chart 500 in the three-dimensional diagram. Images ("A", "B") corresponding to the prints 501, 502 on the test chart 500 and images corresponding to the needles 503, 503 are displayed on the three-dimensional diagram.

[0051] In the present embodiment, an example is shown in which the adjustment setting screens 900 and 930 are displayed after the test chart 500 is output, but the present invention is not limited to this. The adjustment setting screens 900 and 930 may be displayed before or at the same time as the test chart 500 is output.

[0052] Furthermore, the display control unit 403 displays a plurality of selectable patterns indicating states of misalignment on the adjustment setting screens 900 and 930. The display control unit 403 displays a stereoscopic view corresponding to each state of misalignment.

[0053] This allows the user to easily associate the state of the post-processing position on the actual test chart 500 with each of the three-dimensional diagrams displayed on the adjustment setting screens 910 and 930, and makes it easy to understand the position to be measured. In particular, when checking the state of misalignment, it becomes easy to determine which three-dimensional diagram (state) corresponds depending on whether the print "A" 1501 or the print "B" 1502 is in front when the test chart 500 is folded in half.

[0054] Furthermore, the display control unit 403 displays various screens relating to post-processing adjustment settings in the adjustment setting process described below (FIGS. 7 to 10). Details of each screen will be described later.

[0055] Returning to the explanation of Figure 4. The adjustment setting unit 404 accepts settings for adjusting misalignment in post-processing. The adjustment setting unit 404 accepts input of measurement values ​​and selection of the state of misalignment by the user via various screens including the above-mentioned adjustment setting screens 910 and 930.

[0056] The adjustment control unit 405 adjusts the position of post-processing in the finisher 104 based on the settings made by the user in the adjustment setting unit 404. Specifically, the adjustment control unit 405 determines the adjustment value in the finisher 104 based on the measurement values ​​(a) and (b) input in the adjustment setting screens 910 and 930 and the selected state of misalignment.

[0057] For example, in the case of adjusting the folding position, the adjustment control unit 405 determines the movement amount of the positioning member 305 of the finisher 104 based on the measurement value (a) of the folding position input by the user on the adjustment setting screen 910. Also, based on the state of misalignment selected by the user, it determines the movement direction (positive or negative). With the positioning member 305 moved to the reference position of the folding position, the adjustment control unit 405 moves the positioning member 305 by the movement amount in the determined movement direction.

[0058] Similarly, for the adjustment of the staple position, the adjustment control unit 405 determines the movement amount of the positioning member 305 of the finisher 104 based on the measurement value (b) of the staple position input by the user on the adjustment setting screen 930. Also, the adjustment control unit 405 determines the movement direction (positive or negative) based on the state of positional deviation selected by the user. When the positioning member 305 has been moved to the reference position of the staple position, the adjustment control unit 405 moves the positioning member 305 by the movement amount in the determined movement direction.

[0059] Next, the finisher position adjustment process executed by the controller 101 of the MFP 1 will be described. 6 is a flowchart showing the flow of adjustment processing for saddle stitching. In the processing shown in this flowchart, a program stored in storage unit 204 is called by CPU 201, loaded into RAM 202, and executed by CPU 201. In the following description, the symbol "S" means a step.

[0060] When the user operates the setting icon on the home screen (not shown) displayed on the operation unit 106, the setting screen (not shown) is opened, and "Adjust saddle stitch folding position / staple position" is selected, the processing shown in the flowchart of FIG. 6 is started.

[0061] In S601, the CPU 201 displays a start screen 700 on the operation unit 106. The start screen 700 is provided with a message display area 701, a check box 702 for outputting a test chart, a "Next" button 703, a "Cancel" button 704, and the like.

[0062] The message display area 701 displays the following adjustment procedure. 1) Print a test chart. 2) Measure the amount of deviation in the folding position and enter it on the screen. 3) Measure the amount of needle position deviation and enter it on the screen.

[0063] In addition, operation guidance such as "Press 'Next' and follow the on-screen instructions" will be displayed.

[0064] A check box 702 is a selection field for allowing the user to select whether or not to output the test chart 500 in the adjustment setting. The checked state of the check box 702 when the "Next" button 703 is operated is held in the RAM 202 as output setting information for the test chart 500.

[0065] If the check box 702 is checked, the CPU 201 sets "do not print" as the output setting information for the test chart 500. In this case, printing and post-processing of the test chart 500 are not performed in the subsequent processing (S607 to S609). If the check box 702 is not checked, the CPU 201 sets "print" as the output setting information for the test chart 500. In this case, printing and post-processing of the test chart 500 are performed in the subsequent processing (S607 to S609).

[0066] If the user has a printed document that has already been printed and post-processed and can measure the finisher position, the user can skip outputting the test chart 500 and move quickly to the next adjustment setting process.

[0067] In S602, if the user operates the "Next" button 703 on the start screen 700, the process proceeds to S603. If the user operates the "Cancel" button 704, the process of this flowchart ends and the screen returns to the original screen.

[0068] In S603, the CPU 201 acquires information on the target of the finisher position adjustment. In this embodiment, "Adjustment of saddle stitch folding position / staple position" is selected on the setting screen at the start. The CPU 201 acquires the saddle stitch folding position and staple position as information on the adjustment target, and stores the information in the RAM 202. If another adjustment item is selected on the setting screen, the CPU 201 stores information on the selected item as the adjustment target in the RAM 202. On the setting screen, for example, adjustment of the punch position, adjustment of the folding position such as Z-fold or C-fold, etc. can be selected.

[0069] In S604 , the CPU 201 displays the paper selection screen 800 . In S605, the CPU 201 accepts the paper selection by the user.

[0070] Fig. 8 is a diagram showing an example of a paper selection screen 800. As shown in Fig. 8, the paper selection screen 800 is provided with a paper type display area 801, a selected paper display area 802, a "Back" button 803, a "Start Printing" button 804, a "Cancel" button 805, etc.

[0071] In the paper type display area 801, the CPU 201 controls the display so that, among the papers set in the paper feed cassette of the printer 103, papers that can be used in the post-processing to be adjusted can be selected, and unselectable papers cannot be selected. For example, unselectable papers are displayed in gray.

[0072] The CPU 201 acquires paper information for the adjustment target based on the information of the adjustment target acquired in S603. The paper information is stored as post-processing setting information in the RAM 202, the ROM 203, or the storage unit 204. Only usable paper is displayed as selectable, thereby eliminating mistakes in paper selection.

[0073] Furthermore, the CPU 201 displays information about the paper selected by the user in the selected paper display area 802 of the paper selection screen 800 .

[0074] 8, A4R and A3 are displayed as selectable sizes, and A4 is displayed as grayed out so that it cannot be selected. As shown in the selected paper display area 802, A3 paper (plain paper) is selected.

[0075] In S606, the CPU 201 determines whether or not a button has been operated. If operation of the "Start Print" button 804 is detected, the process proceeds to S607. If operation of the "Back" button 803 is detected, the process returns to S601. If operation of the "Cancel" button 805 is detected, the process of this flowchart ends, and the screen returns to the previous screen or the home screen.

[0076] In S607, the CPU 201 acquires output setting information of the test chart 500 (whether or not the check box 702 on the start screen 700 is checked) from the RAM 202. If "Do not print" (checked) is set, the process proceeds to S610. If "Print" (unchecked) is set, the process proceeds to S608.

[0077] In S608, the CPU 201 acquires the information on the adjustment target acquired in S603 and data for outputting a test chart corresponding to the paper selected in S605 from the RAM 202, the ROM 203, or the storage unit 204. In this example, the CPU 201 acquires image data for printing the test chart 500 for saddle stitch adjustment on A3 size paper, and setting information for A3 size saddle stitch processing (information on the folding position and the reference position of the staple position).

[0078] In S609, the CPU 201 performs printing and post-processing (binding and folding) on ​​the selected paper based on the acquired data for outputting the test chart, and then discharges the paper. As a result, the user obtains a test chart 500 as shown in Fig. 5. When the CPU 201 detects that the output of the test chart 500 has been completed (discharged), the process proceeds to S610.

[0079] In S610, the CPU 201 executes an adjustment setting process. In the adjustment setting process, the CPU 201 displays the adjustment setting screens 910 and 930 shown in Fig. 9 on the operation unit 106, and accepts adjustment settings such as input of a positional deviation measurement value and selection of a positional deviation state. The adjustment setting process will be described in detail later. When the user sets the adjustment using the adjustment setting screens 910 and 930 and operates the "Next" button 943, the process proceeds to S611.

[0080] In S611, the CPU 201 executes adjustment of the finisher position based on the measurement value and the state of positional deviation set by the user in S610. The adjustment of the finisher position will be described later. When the adjustment is completed, the process proceeds to S612.

[0081] In S612 , the CPU 201 displays the adjustment completion screen 1010 . 10A is a diagram showing an adjustment completion screen 1010. The adjustment completion screen 1010 is provided with a message display area 1011, a "Start Print" button 1012, and an "End Adjustment" button 1013. The message display area 1011 displays operation guidance such as "Adjustment has been performed. Press [Start Print] to print a test page again and check the results of the adjustment."

[0082] In S613, the CPU 201 accepts a user instruction to print the test chart 500. If the "Start Printing" button 1012 is operated on the adjustment completion screen 1010, the process proceeds to S614. If the "End Adjustment" button 1013 is operated, the adjustment completion screen 1010 is closed, and the process of this flowchart ends.

[0083] In S614, the CPU 201 prints and post-processes the test chart 500, and then discharges it. The CPU 201 outputs the test chart 500 with the adjusted finisher positions (folding position, binding position). The user can check the adjusted test chart 500 to see if the desired adjustments have been made.

[0084] In S615, the CPU 201 displays the output completion screen 1020 of the adjusted test chart 500. 10(b) is a diagram showing an output completion screen 1020 of the adjusted test chart 500. The output completion screen 1020 is provided with a message display area 1021, a "Readjust" button 1022, and an "End adjustment" button 1023. The message display area 1021 displays operation guidance such as "Please check the test chart. Press [Readjust] to proceed to the screen for measuring the amount of deviation again."

[0085] In S616, the CPU 201 accepts an instruction for readjustment or end of adjustment from the user. If the "Readjust" button 1022 is pressed on the output completion screen 1020, the process returns to S610. If the "End Adjustment" button 1023 is pressed, the output completion screen 1020 is closed and the process of this flowchart ends.

[0086] Next, the adjustment setting process executed in S610 of FIG. 6 will be described. FIG. 11 is a flowchart showing the flow of the adjustment setting process.

[0087] In S1101, the CPU 201 checks the information of the adjustment target acquired in S603. If the adjustment target is saddle stitching, the process proceeds to S1102. If the adjustment target is not saddle stitching, the process proceeds to S1104. If the adjustment target is not saddle stitching, for example, the adjustment target selected on the setting screen is other than saddle stitching, such as adjustment of punch position or folding position.

[0088] In S1102, the CPU 201 first displays the folding position adjustment setting screen 910 shown in FIG. 9A, and executes the folding position adjustment setting process.

[0089] Next, in S1103, the CPU 201 displays the staple position adjustment setting screen 930 shown in FIG. 9B, and executes the adjustment setting process of the staple position (binding position).

[0090] In S1102 and S1103, when the user completes input of the measurement values ​​and selection of the state of positional deviation and operates the "Next" button 943 on the adjustment setting screen 930, the processing of this flowchart ends.

[0091] If the adjustment target is other than saddle stitching, in S1104, the CPU 201 displays an adjustment setting screen for the finisher position according to the adjustment target (for example, FIG. 16) and accepts input of measurement values. The CPU 201 determines adjustment values ​​for the finisher based on the input measurement values ​​and stores them in the RAM 202. FIG. 16 shows an example of an adjustment setting screen 1600 for the punch position in the center-folding saddle punch process.

[0092] Also, for example, when adjustment of only folding or binding is the target, only the folding position adjustment setting screen 910 or only the staple position adjustment setting screen 930 is displayed to accept adjustment settings by the user. When adjustment is made to a finisher process that folds in two places, such as Z-folding or C-folding, an adjustment setting screen for inputting measurement values ​​and misalignment conditions for the two folding positions is displayed to accept adjustment settings by the user. When adjustment is made to a punching process, an adjustment setting screen for the punching position is displayed to accept adjustment settings by the user.

[0093] As with saddle-stitching, the adjustment setting screen for each of these finisher processes displays a printout that shows the top, bottom, left, and right, as well as a three-dimensional diagram showing the test chart that has been subjected to the finisher process to be adjusted, and measurement points are indicated on the three-dimensional diagram.

[0094] The folding position adjustment setting process in S1102 of Fig. 11 will be described with reference to Fig. 9(a) and Fig. 12. Fig. 12 is a flowchart illustrating the flow of the folding position adjustment setting process.

[0095] In S1201, the CPU 201 first displays a folding position adjustment setting screen 910 on the operation unit 106. Fig. 9(a) is a diagram showing an example of the folding position adjustment setting screen 910. The folding position adjustment setting screen 910 is provided with buttons 911, 912, and 913 for selecting a state of misalignment of the folding position, and three-dimensional diagrams 914, 916, and 918 showing the state of misalignment of the folding position.

[0096] The folding position adjustment setting screen 910 also has an input field 920 for the amount of deviation (a), “+” and “-” buttons 921 for inputting a value into the input field 920, a “Cancel” button 922, and a “Next” button 923.

[0097] Three-dimensional diagrams 914, 916, and 918 are schematic diagrams showing test chart 500 in three dimensions, and display "A" or "B" corresponding to prints 501 and 502 applied to test chart 500. By checking "A" or "B" displayed in three-dimensional diagrams 914, 916, and 918, the user can easily check the surface and up-down direction of test chart 500, and whether the folding position is on the left or right.

[0098] Three-dimensional diagram 914 shows a state in which "A is shorter", which is one of the patterns of misalignment of folding positions. Button 911 is a button for selecting the state in which "A is shorter". Three-dimensional diagram 916 shows a state in which "A and B are equal", which is one of the patterns of misalignment of folding positions. Button 912 is a button for selecting the state in which "A and B are equal". Three-dimensional diagram 918 shows a state in which "B is shorter", which is one of the patterns of misalignment of folding positions. Button 913 is a button for selecting the state in which "B is shorter".

[0099] The stereoscopic view 916 and the button 912 indicate a state in which there is no positional deviation. This allows the user to explicitly select that there is no positional deviation. Also, this enables error detection in the subsequent step (S1206).

[0100] The letter "a" shown in the three-dimensional diagram 914 is a measurement point 915. In other words, when the print "A" on the test chart 500 is held in front and the front side is shorter, the position corresponding to the measurement point 915 is measured.

[0101] Similarly, in the three-dimensional diagram 918, with the print "B" facing forward, a measurement point 919 of the amount of misalignment (a) is shown on the left side. Since the three-dimensional diagram 916 shows a state in which there is no misalignment, only an arrow and a straight line are shown at the measurement point 917, and the letter "a" indicating the amount of misalignment is not displayed.

[0102] In S1202, the CPU 201 accepts input of the state of misalignment of the folding position and the amount of misalignment (a). The user determines the state of misalignment of the folding position from the folding state of the test chart 500 output in S609 (or S614), and selects one of the states shown by buttons 911, 912, and 913. The user also measures the measurement point a of the test chart 500, and inputs the measurement value into an input field 920 for the amount of misalignment (a) of the folding position.

[0103] When the button 912 indicating a state in which there is no positional deviation is selected, the CPU 111 may display "0.0" in the input field 920 for the deviation amount (a).

[0104] In S1203, the CPU 201 determines whether or not the "Next" button 923 has been operated on the folding position adjustment setting screen 910. If the "Next" button 923 has been operated, the process proceeds to S1204. If the "Next" button 923 has not been operated and the "Cancel" button 922 has been operated instead, the process returns to S1201.

[0105] In S1204, the CPU 201 acquires the state of misalignment input in S1202. That is, the state of misalignment in the folding process is acquired based on which of the buttons 911, 912, and 913 was operated in S1202.

[0106] In S1205, the CPU 201 acquires the value of the amount of deviation (a) input by the user in the input field 920 in S1202.

[0107] In S1206, the CPU 201 determines whether there is a contradiction between the acquired state of positional deviation and the amount of deviation (a). For example, if "A is shorter" (button 911) or "B is shorter" (button 913) is selected as the state of positional deviation and "0" is input into the amount of deviation (a), the CPU 201 determines that there is a contradiction. Also, if "A and B are equal" (button 912) is selected as the state of positional deviation and a value other than "0" is input into the amount of deviation (a), the CPU 201 determines that there is a contradiction.

[0108] If it is determined in S1206 that there is a contradiction between the selected state of positional deviation and the input amount of deviation (a), the CPU 201 proceeds to S1207. In S1207, the CPU 201 issues an error notification. Thereafter, the process returns to S1201. If it is determined in S1206 that there is no contradiction between the selected state of positional deviation and the input amount of deviation (a), the process proceeds to S1208.

[0109] If the deviation amount (a) input in the input field 920 of the adjustment setting screen 910 is not within the range that can be input, the process may proceed to S1207 as an input value error and an error notification may be issued. The range that can be input for the deviation amount (a) is determined in advance and is stored in the RAM 202, the ROM 203, or the storage unit 204.

[0110] In S1208, the CPU 201 first determines the selected state of misalignment in order to calculate the adjustment value for the position in the folding mechanism. If "A is shorter" (button 911) is selected, the process proceeds to S1209. If "B is shorter" (button 913) or "A and B are equal" (button 912) is selected, the process proceeds to S1210.

[0111] In S1209, the CPU 201 converts the value of the deviation amount (a) input in the input field 920 to a negative value and stores it as an adjustment value for the folding position in the storage unit 204 or the RAM 202. For example, if the value of the deviation amount (a) input in the input field 920 is "2.0" [mm], the adjustment value is determined to be "-2.0" [mm]. After that, the adjustment value is stored and the processing of this flowchart ends.

[0112] In S1210, the CPU 201 determines the value of the deviation amount (a) input in the input field 920 as it is, that is, as a positive adjustment value, and stores it in the storage unit 204 or the RAM 202. After that, the process of this flowchart ends.

[0113] Note that the CPU 201 may store the fact that the folding position adjustment setting process has been performed in S1209 and S1210, and the determined adjustment values ​​together with the date and time in the storage unit 204 or the RAM 202. By recording the adjustment history, it becomes possible to read out the implementation status of the folding position adjustment at any time and display it on the operation unit 106 for the user to confirm.

[0114] Next, the adjustment setting process of the hand position in S1103 will be described with reference to Fig. 9(b) and Fig. 13. Fig. 13 is a flowchart illustrating the flow of the adjustment setting process of the hand position.

[0115] In S1301, the CPU 201 first displays a needle position adjustment setting screen 930 on the operation unit 106. Fig. 9(b) is a diagram showing an example of the needle position adjustment setting screen 930. The needle position adjustment setting screen 930 is provided with buttons 931, 932, and 933 for selecting a state of misalignment of the needle positions, and three-dimensional diagrams 934, 936, and 938 showing the states of misalignment of the needle positions.

[0116] The needle position adjustment setting screen 930 also has an input field 940 for the amount of deviation (b), “+” and “-” buttons 941 for inputting a value into the input field 940, a “Cancel” button 942, and a “Next” button 943.

[0117] The three-dimensional diagrams 934, 936, and 938 are diagrams showing the test chart 500 in three dimensions, and display "A" or "B" corresponding to the printing 501, 502 applied to the test chart 500. By checking the "A" or "B" displayed in the three-dimensional diagrams 934, 936, and 938, the user can easily check the surface and up-down direction of the test chart 500, and whether the needle position is on the left or right.

[0118] Three-dimensional diagram 934 shows one pattern of needle position misalignment, that is, "displaced toward A." Button 931 is a button for selecting the "displaced toward A" state. Three-dimensional diagram 936 shows one pattern of needle position misalignment, that is, "matches the fold position." Button 932 is a button for selecting the "matches the fold position" state. Three-dimensional diagram 938 shows one pattern of needle position misalignment, that is, "displaced toward B." Button 933 is a button for selecting the "displaced toward B" state.

[0119] There is no misalignment of the stereoscopic view 936 and the button 932. This allows the user to explicitly select that there is no misalignment. Also, this enables error detection in the subsequent step (S1306).

[0120] The letter "b" shown in the three-dimensional diagram 934 is a measurement point 935. That is, the measurement point 935 is shown when the needle position is to the right of the folding position with the print "A" of the test chart 500 facing forward. Similarly, three-dimensional view 938 shows measurement point 939 when the needle position is to the left of the fold position with print "B" facing forward. Since three-dimensional view 936 shows a state where the needle position matches the fold position and there is no misalignment, measurement point 937 is not displayed.

[0121] In S1302, the CPU 201 accepts input of the state of needle position misalignment and the amount of misalignment (b). The user determines the state of needle position misalignment from the positional relationship between the needle position and the folding position of the test chart 500 output in S609 (or S614), and selects one of the states shown by buttons 931, 932, and 933. The user also measures the measurement point b of the test chart 500, and inputs the measurement value in an input field 940 for the amount of misalignment (b) of the needle position.

[0122] When the button 932 indicating a state in which there is no positional deviation is selected, the CPU 111 may display "0.0" in the input field 940 for the deviation amount (b).

[0123] In S1303, the CPU 201 determines whether or not the "Next" button 943 has been operated on the needle position adjustment setting screen 930. If the "Next" button 943 has been operated, the process proceeds to S1304. If the "Next" button 943 has not been operated and the "Cancel" button 942 has been operated, the process returns to S1301.

[0124] In S1304, the CPU 201 acquires the state of positional deviation input in S1302. That is, the state of positional deviation of the needle position is acquired based on which of the buttons 931, 932, and 933 was operated in S1302.

[0125] In S1305, the CPU 201 acquires the value of the amount of deviation (b) input by the user in the input field 940 in S1302.

[0126] In S1306, the CPU 201 determines whether there is a contradiction between the acquired state of misalignment and the amount of misalignment (b). For example, if "misaligned toward A" (button 931) or "misaligned toward B" (button 933) is selected as the state of misalignment and "0" is input into the amount of misalignment (b), the CPU 201 determines that there is a contradiction. Also, if "matched with the folding position" (button 932) is selected as the state of misalignment and a value other than "0" is input into the amount of misalignment (b), the CPU 201 determines that there is a contradiction.

[0127] If it is determined in S1306 that there is a contradiction between the selected state of positional deviation and the input amount of deviation (b), the CPU 201 proceeds to S1307. In S1307, the CPU 201 issues an error notification. Then, the process returns to S1301. If it is determined in S1306 that there is no contradiction between the selected state of positional deviation and the input amount of deviation (b), the process proceeds to S1308.

[0128] If the deviation amount (b) input in the input field 940 of the adjustment setting screen 930 is not within the range that can be input, the process may proceed to S1307 as an input value error and an error notification may be issued. The range that can be input for the deviation amount (b) is determined in advance and is stored in the RAM 202, the ROM 203, or the storage unit 204.

[0129] In S1308, CPU 201 first determines the selected state of positional deviation in order to calculate the adjustment value for the position in the staple mechanism. If "Misaligned toward A" (button 931) or "Matched with the folding position" (button 932) is selected, proceed to S1309. If "Misaligned toward B" (button 933) is selected, proceed to S1310.

[0130] In S1309, the CPU 201 converts the value of the deviation amount (b) input in the input field 940 to a negative value, and stores it in the storage unit 204 or the RAM 202 as an adjustment value for the needle position. For example, if the value of the deviation amount (b) input in the input field 940 is "2.0" [mm], it is determined to be "-2.0" [mm]. Thereafter, the adjustment value is stored, and the processing of this flowchart ends.

[0131] In S1310, the CPU 201 determines the value of the deviation amount (b) input in the input field 940 as it is, that is, as a positive adjustment value, and stores it in the storage unit 204 or the RAM 202. Then, the process of this flowchart ends.

[0132] Note that the CPU 201 may store in the storage unit 204 or the RAM 202, etc., in S1309 and S1310 the fact that the hand position adjustment setting process has been performed and the determined adjustment value together with the date and time. By recording the adjustment history, it becomes possible to read out the implementation status of the hand position adjustment at any time and display it on the operation unit 106 for the user to confirm.

[0133] When the adjustment values ​​of the folding position and staple position are determined by the processing of the flowcharts in FIGS. 12 and 13, the CPU 201 sets the adjustment values ​​of the folding position and staple position in the finisher 104 in S611 in FIG. FIG. 14 is a diagram for explaining adjustment of the finisher position.

[0134] FIG. 14(a) is a diagram for explaining adjustment of the staple position. When performing stapling, the CPU 201 moves the positioning member 305 from the reference position of the staple position by an adjustment value determined in the adjustment setting process. The direction of movement is determined by the positive or negative value of the adjustment value. If the adjustment value is a positive value (+b), the CPU 201 moves the positioning member 305 upward from the reference position of the staple position along the tray 306. If the adjustment value is a negative value (-b), the CPU 201 moves the positioning member 305 downward from the reference position of the staple position along the tray 306. The amount of movement is "b".

[0135] FIG. 14(b) is a diagram for explaining the adjustment of the folding position. When performing the folding process, the CPU 201 moves the positioning member 305 from the reference position of the folding position by an adjustment value determined in the adjustment setting process. The direction of movement is determined by whether the adjustment value is positive or negative. If the adjustment value is a positive value (+a), the CPU 201 moves the positioning member 305 upward from the reference position of the folding position along the tray 306. If the adjustment value is a negative value (-a), the CPU 201 moves the positioning member 305 downward from the reference position of the folding position along the tray 306. The amount of movement is "a".

[0136] Thereafter, the CPU 201 outputs the adjusted test chart 500 in accordance with the user's operation. The user checks the fold positions and staple positions of the adjusted test chart 500 and determines whether to perform readjustment or to end the adjustment.

[0137] As described above, in this embodiment, the MFP 1 outputs the test chart 500 that can uniquely identify the printing surface and the orientation of the paper. In addition, a stereoscopic view corresponding to the test chart 500 is displayed on the adjustment setting screens 910 and 930, and the printing surface and the measurement points of the test chart 500 are shown in the stereoscopic view. This makes it easy for the user to associate the orientation of the test chart 500 and the top, bottom, left, and right of the paper with the display on the screen, and also makes it easy to grasp the measurement points. This also makes it easy to input measurement values ​​on the adjustment setting screens 910 and 930, improving operability in adjusting the post-processing position.

[0138] In the above-mentioned flowchart, an example is shown in which the folding position is adjusted and the staple position is adjusted later, but the order of adjustment and setting is not important. For example, the staple position may be adjusted and the folding position may be adjusted later, or both may be displayed simultaneously (on the same screen). In addition, an example is shown in which adjustment values ​​for the folding mechanism and the staple mechanism are calculated from the measurement values ​​and the state of deviation inputted to the adjustment setting screen, but this is just one example, and the calculation method can be changed as appropriate depending on the structure and positional relationship of each mechanism.

[0139] Furthermore, in the present embodiment, the adjustment of saddle stitching has been described as an example, but the present invention can also be applied to adjustment of post-processing other than saddle stitching.

[0140] <Second embodiment> Next, as a second embodiment, adjustment settings for post-processing combining center folding and saddle punching will be described. In addition to a folding mechanism, the finisher 104 is provided with a punching mechanism for performing punching. Other hardware configurations and functional configurations of the MFP1 are the same as those of the first embodiment. Below, differences from the first embodiment will be described.

[0141] 15 is a diagram showing an example of a test chart 1500 that is output when adjusting post-processing that combines center folding and saddle punching. Center folding is a folding process that folds the paper in two at the center of the length in the transport direction. Saddle punching is a process that forms punch holes at symmetrical positions on both sides of the fold position.

[0142] 15 has punch holes 1503a, 1503b, 1503c, and 1503d formed therein. Also, "A" 1501 is printed on the right side of the paper, and "B" 1502 is printed on the left side. Test chart 1500 is output in a size specified by the user. If post-processing is performed at the standard folding and punching positions, center line 1504 will coincide with the folding position, and punch holes 1503a and 1503b, and 1503c and 1503d will be formed at symmetrical positions on both sides of the folding position (center line 1504).

[0143] The prints 1501 and 1502 on the test chart 1500 allow the user to uniquely identify the print surface and paper orientation of the test chart 1500. The prints on the test chart 1500 are not limited to alphabets such as "A" and "B" and may be other characters that can be distinguished from top to bottom or left to right, or may be marks, figures, patterns, or combinations of these.

[0144] 3D diagrams 1610 and 1612 corresponding to the test chart 1500 are displayed on a center-fold saddle punch adjustment setting screen 1600.

[0145] 16 is a diagram showing an example of a punch position adjustment setting screen 1600. The punch position adjustment setting screen 1600 is provided with three-dimensional views 1610 and 1612, input fields 1620 and 1622 for punch position measurement values ​​(a) and measurement values ​​(b), and "+" and "-" buttons 1621 and 1623 for inputting values ​​into the input fields 1620 and 1622. The adjustment setting screen 1600 also is provided with a "Cancel" button 1624 and a "Next" button 1623.

[0146] The three-dimensional diagrams 1610 and 1612 are schematic diagrams showing the test chart 1500 in three dimensions, and depict the prints 1501, 1502 and punched holes 1503a to 1503d of the test chart 1500. This makes it easy for the user to distinguish between the sides and the top and bottom of the actual test chart 1500.

[0147] The letter "a" shown in the three-dimensional diagram 1610 is the measurement point 1611. In other words, it is shown that the distance between (the center of) the punch hole on the side of the test chart 1500 on which the print "A" is printed and the folding position is the measurement point of the measurement value (a). Similarly, the letter "b" shown in the three-dimensional diagram 1612 is the measurement point 1613. In other words, it is shown that the distance between (the center of) the punch hole on the side of the test chart 1500 where the print "B" is located and the folding position is the measurement point for the measurement value (b).

[0148] The user measures measurement points 1611 and 1613 using test chart 1500, and inputs the measurement values ​​(a) and (b) into input fields 1620 and 1622, respectively. When the "Next" button is then operated, CPU 111 calculates adjustment values ​​for the punch mechanism of finisher 104 based on the input values.

[0149] For example, if a = 5 [mm] and b = 15 [mm] are entered, the adjustment amount for the punch position is calculated as (ba) / 2 = 5 [mm], and the adjustment direction is the positive direction (towards the right (face A)). Note that this example is based on the assumption that the folding position has already been adjusted. The expected values ​​for a=b=10 [mm] are those for which no adjustment is required.
