Here, an example is shown in which the side edge of the paper P is cut and the size of the paper P in the CD direction is adjusted. For the FD direction of the paper P, the cutting unit 380 performs the edge processing and adjusts the size.

  In the image forming system according to the present embodiment, as described later, when a sheet runs out during image formation, a sheet having a size larger than that of the sheet that has run out of paper (refer to size information and sheet information and cutting). The paper that matches the size information) is controlled to be fed to determine the peripheral area to be cut to match the size of the paper that has run out of paper, and the peripheral area Control is performed so that an image is formed in an area other than the area, and a peripheral area of the image-formed sheet is cut.

  The slitter unit 320 is configured to include disk-shaped blades 320a and 320b in order to cut the conveyance direction side end (the final top of the booklet) of the conveyed paper. The blades 320a and 320b are not limited to a disk shape, and may be blades of various shapes that cut the end of the sheet being conveyed in the conveyance direction. It should be noted that the cutting of the end portion of the sheet P in the transport direction on the slitter unit 320 is a kind of cutting.

  Here, when the paper P is transported in the X direction, the blades 320a and 320b can be adjusted in position in the ± Y direction (conveyance orthogonal direction) according to the cut amount. Then, the blades 320a and 320b are driven in the −Z direction to come into contact with the sheet P being conveyed, whereby the sheet Pbefore conveyance direction side ends Pcut11 and Pcut12 are cut, and the sheet Pafter1 is further subjected to other post-processing. Therefore, it is conveyed in the X direction. The blades 320a and 320b are adjusted in position in the ± Y direction, whereby the cut amounts Ycut11 and Ycut12 are adjusted, and the width Yafter of the paper Pafter1 is adjusted to the same value as the desired paper. .

[Operation (1) of the embodiment]
Hereinafter, the operation (1) of the image forming system, the image forming control apparatus, and the image forming system control method of the present embodiment will be described according to the operation procedure.

  Note that the operation (1) of this embodiment may be determined and controlled by the control unit 101 as a main body, and the control unit 301 of the sheet processing apparatus 300 is not limited thereto. Judgment and control may be performed as a main body, or a control unit (not shown) in the information processing apparatus connected to the image forming system may perform similar control. In the following description of the operation, a specific example is given of the case where the control unit 101 performs determination and control mainly.

  First, before starting the image formation, the operator selects “various settings” on the menu screen (103Ge in FIG. 7) via the operation display screen 103G of FIG. The “paper out operation setting” tab (103Gf1 in FIG. 7) in the various setting screens (103Gf in FIG. 7) is pressed. When the operator presses the OK button 103Gb1, the control unit 101 displays an operation setting screen (103Gf ′ in FIG. 8) upon receipt of the operation display screen 103G.

  In the out-of-paper operation setting screen 103Gf ′ of FIG. 8, a schematic explanation display (103Gf20 in FIG. 8) for cutting a sheet of a size larger than an empty sheet is displayed, and setting items of operation setting at the time of out-of-paper 103Gf21 to 103Gf23 are displayed. According to the screen display, the operator inputs a selection as to whether to use the paper switching function (103Gf21), how many sheets to use (103Gf22), whether to use even if the charge changes (103Gf23), and so on. In the operation of this embodiment, since a large sheet is used when the sheet runs out, billing or the like may change, so the operator's intention is confirmed in advance.

  FIG. 9 is a flowchart showing the basic operation of the present embodiment.

  First, the control unit 101 determines a processing mode in accordance with the contents of print information of a job or an operation input to the operation display unit 103 by an operator, and executes image formation. Note that the print information includes image data to be imaged, size information such as what paper an image is to be formed on, information on how many sheets or how many images are to be formed, and the like.

  In this case, the control unit 101 refers to the size information included in the print information and the sheet information regarding the sheets stored in the sheet feeding unit 105, and supplies a sheet having a size that matches the size information from the sheet feeding unit 105. It is controlled to make paper.

  In this state, the control unit 101 that has received the out-of-paper information from the paper supply unit 105 because the paper in the tray being supplied becomes empty and starts control according to the flowchart shown in FIG. 9 (start in FIG. 9). ).

  First, the control unit 101 refers to the size information and the sheet information, and can switch to another tray that accommodates the same size sheet to continue image formation, or can switch to another tray that accommodates a larger size sheet and continue image formation. A tray switching determination process is performed to determine whether the image formation cannot be continued by switching to any tray (step S101 in FIG. 9).

  Here, a subroutine of tray switching determination processing will be described with reference to the flowchart of FIG.

  First, the control unit 101 determines whether the same size paper as the paper emptied during image formation is stored in a different tray, the size information included in the print information, and the paper stored in the paper supply unit 105. Judgment is made with reference to the sheet information (step S201 in FIG. 10).

  If a sheet of the same size as the sheet emptied during image formation is stored in another tray of the sheet feeding unit 105 (YES in step S201 in FIG. 10), the control unit 101 selects the same tray of the corresponding another tray. By switching to size paper, it is determined that image formation is “continuable” (step S202 in FIG. 10).

  On the other hand, when a sheet that is the same size as the sheet emptied during image formation is not stored in another tray of the sheet feeding unit 105 (NO in step S201 in FIG. 10), the control unit 101 executes the job being executed. Then, it is determined whether or not the same size paper is used for the job to be executed next (step S203 in FIG. 10).

  If the same size paper is used for the job being executed and the job to be executed next (YES in step S203 in FIG. 10), the same problem continues to occur in the next job, so the current job Then, although there is a possibility of being able to continue, the control unit 101 determines that “continuation is impossible” (step S204 in FIG. 10).

  Here, when the same size paper is not used for the job being executed and the job to be executed next (NO in step S203 in FIG. 10), the current job can be switched to a larger size paper. Since it may be possible to continue image formation, the following determination is continued.

  First, the control unit 101 acquires the paper size of the tray [i] for the i-th tray (tray [i]) with i = 1 for a plurality of trays of the paper feeding unit 105 (step S205 in FIG. 10). , S206).

  It is determined whether the paper size in the FD direction of the acquired tray [i] is equal to or larger than the paper emptied during image formation (hereinafter, “empty paper”) (step S207 in FIG. 10). Note that, as shown in FIG. 4, the FD direction is the sheet length in the transport direction, and the difference is cut by the cutting unit 380 after the booklet state.

  If the obtained paper size in the FD direction of the tray [i] is equal to or larger than the blank paper (YES in step S207 in FIG. 10), the portion larger than the blank paper in the FD direction (hereinafter referred to as “FD direction difference”). ) Is within a range that can be cut by the cutting unit 380 (step S208 in FIG. 10). The control unit 101 obtains the operation information of the cutting unit 380, and determines that cutting is not possible when the FD direction difference is smaller than or larger than the cuttable range.

  Further, it is determined whether the obtained paper size in the CD direction of the tray [i] is equal to or larger than the empty paper (step S209 in FIG. 10). Note that, as shown in FIG. 4, the CD direction has a sheet width in a direction orthogonal to the conveyance direction, and is cut during conveyance by the slitter unit 320 before being put into a booklet state.

  If the paper size in the CD direction of the acquired tray [i] is equal to that of the empty paper (YES in step S209 in FIG. 10), it is not necessary to cut the CD direction, and it is necessary to cut only the FD direction. is there. Note that while the CD direction is cut for each sheet being conveyed, the FD direction is cut into a plurality of pages in a booklet state. That is, the cut in the CD direction may reduce productivity (the number of sheets that are formed and output per unit time). Therefore, in the case of cutting only in the FD direction, the control unit 101 is about 0.8 with respect to the difference amount of the sheet area (the sheet area to be cut and discarded, hereinafter referred to as “sheet area difference amount”). Is multiplied by a coefficient less than 1 and stored as the difference amount of tray [i] (step S212 in FIG. 10).

  Note that the time required for cutting and cutting may vary depending on the structure of the slitter unit 320 and the structure of the cutting unit 380. For this reason, the cutting and cutting time required per sheet is calculated, the above-mentioned coefficients are determined, and the above difference amounts are calculated so that the one with the short processing time is ultimately selected. It is desirable.

  Further, when the CD size of the acquired tray [i] is larger than the empty paper (YES in step S209 in FIG. 10), the portion (hereinafter referred to as “CD”) that is larger than the empty paper in the CD direction. The control unit 101 determines whether or not the “direction difference” is a range that can be cut by the slitter unit 320 (step S210 in FIG. 10). The control unit 101 obtains the operation information of the slitter unit 320, and determines that cutting is impossible when the CD direction difference is smaller than or larger than the cuttable range.

  Also, if the CD size of the acquired tray [i] is larger than the blank paper (YES in step S209 in FIG. 10) and the CD direction difference can be cut by the slitter unit 320 (in FIG. 10). In step S210, YES), the control unit 101 calculates the sheet area difference amount and stores it as the difference amount of the tray [i] (step S211 in FIG. 10).

  In the above determination (steps S207 to S210 in FIG. 10), the paper size in the FD direction of the acquired tray [i] is not equal to or larger than the empty paper (NO in step S207 in FIG. 10). The paper size in the FD direction is equal to or larger than the blank paper, but cannot be trimmed by the trimming unit 380 (NO in step S208 in FIG. 10), and the paper size in the CD direction of the acquired tray [i] is not larger than the blank paper (in FIG. 10). No in step S209), and the acquired tray [i] has a paper size in the CD direction that is equal to or larger than the empty paper but cannot be cut by the slitter unit 320 (NO in step S210 in FIG. 10). Alternatively, when the difference amount of the tray [i] is stored (steps S211 and S212 in FIG. 10), if there is a sheet of another tray that has not been determined (the scan in FIG. 10). In-up S213 YES), the i + 1 is replaced with i for another paper tray of undetermined continues the determination processing (step S214 in FIG. 10).

  As described above, when all the sheets stored in the tray connected to the sheet feeding unit 105 are determined (NO in step S213 in FIG. 10), the FD direction and the CD of the sheet in another tray are determined. If there is a different size paper whose direction is equal to or larger than the empty paper and can be cut or trimmed (YES in step S215 in FIG. 10), the control unit 101 has a paper area difference amount compared to the empty paper. By switching to the tray of the smallest different size paper, it is determined that image formation is “continuable” (step S216 in FIG. 10).

  In the calculation of the sheet area difference amount in steps S211 and S212, when only the FD direction is cut without cutting the CD direction, the calculation of the sheet area difference amount is multiplied by a coefficient less than 1, so that the actual difference is calculated. Even if the paper area difference amount is the same, paper that does not deteriorate productivity is preferentially selected.

  As described above, the tray switching determination process is performed (step S101 in FIG. 9), and if the determination result cannot be continued (“uncontinuable” in step S102 in FIG. 9), the control unit 101 runs out of paper. A display screen (see FIG. 11) for prompting the replenishment of the paper size capable of continuing the job in the tray is displayed on the operation display unit 103 (step S103 in FIG. 9). In the operation display screen 103G of FIG. 11, the message screen 103Gg displays a first message screen 103Gg11 that prompts the user to supply paper while indicating that the paper has run out. And a third message screen 103Gg13 indicating that it is possible to continue even if a large size of paper is replenished.

  Accordingly, the operator may supply the same size paper to the tray that is out of paper, or may supply a large size paper that can be used by cutting. In this case, the control unit 101 suspends image formation until paper sheets of the same size or different sizes are replenished to the tray that is out of paper (step S104 in FIG. 9), and resumes image formation after the paper is replenished.

  Note that the control unit 101 has a range that can be accommodated in the tray with a CD direction that is equal to or larger than the CD direction size of the blank sheet and that can be cut by the slitter unit 320. A sheet having a size that is smaller than the size that can be cut in 380 and that can be accommodated in the tray is displayed on the third message screen 103Gg13 as a different size sheet that can be switched.

  Further, if the determination result of the tray switching determination process (step S101 in FIG. 9) can be continued by switching to another tray / the same size paper (“continue switching of the same size paper” in step S102 in FIG. 9). The control unit 101 switches to another tray containing the same size paper in the paper supply unit 105 (step S105 in FIG. 9), and sets each unit to continue image formation without changing settings other than tray switching. Control is performed (step S106 in FIG. 9). In this case, the operation display unit 103 may display that the tray has been switched to the same size sheet although the sheet has run out, or may not be displayed.

  If the determination result of the tray switching determination process (step S101 in FIG. 9) can be continued by switching to another tray / different size paper (“continuation of different size paper can be continued” in step S102 in FIG. 9). The control unit 101 determines whether the number of sheets of different sizes on different trays to be switched and used is equal to or less than a predetermined number (103Gf in FIG. 8) (step S107 in FIG. 9).

  Although the determination result of the tray switching determination process can be continued by switching to another tray / different size paper, the number of different size sheets in another tray to be used by switching is a predetermined number (103Gf22 in FIG. 8). If it exceeds (NO in step S107 in FIG. 9), the control unit 101 displays an operation display on a display screen (see FIG. 12) that prompts the user to replenish the paper size that allows the job to be continued in the tray that has run out of paper. Displayed on the unit 103. In the operation display screen 103G of FIG. 12, in the message screen 103Gg, the first message screen 103Gg11 that prompts the user to replenish paper while indicating that the paper has run out, and the first that indicates that if there is a large size paper when the paper runs out, A second message screen 103Gg12 and a third message screen 103Gg13 for inquiring whether to switch to a different size paper because there is a different size paper that can be switched to another tray. Therefore, the operator may replenish paper in a tray that is out of paper, or may approve switching to a tray of a different size paper that exceeds a predetermined setting.

  Although the determination result of the tray switching determination processing can be continued by switching to another tray / different size paper, it is set not to use the function of switching to another tray (103Gf21 in FIG. 8) (in FIG. 9). In step S108, NO), the control unit 101 displays on the operation display unit 103 a display screen (see FIG. 12) that prompts the user to supply a paper size that allows the job to be continued in the tray that has run out of paper. The operation display screen 103G of FIG. 12 includes a third message screen 103Gg13 inquiring whether to switch to a different size sheet because there is a different size sheet that can be switched to another tray. Accordingly, the operator may replenish the paper in the tray that is out of paper, or may approve switching to a tray of a different size paper.

  The determination result of the tray switching determination process can be continued by switching to another tray / different size paper, the number of different size paper used is less than the setting, and tray switching is permitted (in step S107 in FIG. 9). YES, YES in S108), the control unit 101 determines the peripheral area as waste to be cut and cut off by the slitter unit 320 from the information from the storage unit 395 and the peripheral area generated when different size paper is used. It is determined whether or not the peripheral area as the waste cut and cut by the cutting unit 380 can be stored in the storage unit 395 until the end of the job (step S109 in FIG. 9). If the peripheral area as waste cannot be stored in the storage unit 395 until the end of the job (NO in step S109 in FIG. 9), the control unit 101 can continue the job in the tray out of paper. A display screen (see FIG. 12) for prompting the replenishment of the paper size is displayed on the operation display unit 103.

  The judgment result of the tray switching judgment process can be continued by switching to another tray or different size paper, the number of different size paper used is less than the setting, tray switching is permitted, and the peripheral area as waste is the job If it can be accommodated in the accommodation unit 395 until the end (YES in step S107 in FIG. 9, YES in S108, YES in S109), the control unit 101 changes the charge when switching to another tray / different size paper. It is determined whether or not it occurs (step S111 in FIG. 9).

  If the billing change occurs due to switching to another tray / different size paper (YES in step S111 in FIG. 9), the control unit 101 occurs by switching to another tray / different size paper when the paper runs out. A display screen (see FIG. 13) urging approval for the charge change is displayed on the operation display unit 103 (step S112 in FIG. 9). In the operation display screen 103G of FIG. 12, since there is a different size paper that can be switched to another tray, it is possible to switch to a different size paper, and a third message screen for inquiring whether to approve the charge change at that time 103Gg13 is included.

  Therefore, if the operator does not approve the charge change (“suspend” in step S113 in FIG. 9), the control of the control unit 101 prompts the user to replenish the paper size that allows the job to be continued in the tray that has run out of paper. A display screen (see FIG. 11) is displayed on the operation display unit 103 (step S103 in FIG. 9), image formation is interrupted until paper is replenished to the tray that is out of paper, and image formation is resumed after paper is replenished (see FIG. 11). Step S104 in FIG. 9).

  On the other hand, the determination result of the tray switching determination process can be continued by switching to another tray / different size paper, the number of different size paper used is less than the setting, tray switching is permitted, and the peripheral area as waste is When the job can be stored in the storage unit 395 until the end of the job (YES in step S107 in FIG. 9, YES in S108, YES in S109), and there is no change in charge even when switching to another tray / different size paper (NO in step S111 in FIG. 9), or if the operator approves the charge change (“continuation” in step S113 in FIG. 9), the control unit 101 determines that the tray is out of paper. Control is performed so as to switch the sheet feeding to another tray / different size sheet that minimizes the difference between the sheet and the sheet area (step S114 in FIG. 9). Depending on the number of sheets stored in different trays and different sized sheets, the sheet area difference amount is not minimum, but it may be controlled to switch the sheet feeding to a tray having the number of sheets necessary to continue image formation. Good.

  Further, the control unit 101 determines a peripheral region as shown in either FIG. 5 or FIG. 6, controls the image forming unit 150 to form an image in a region other than the peripheral region, and sets the peripheral region to a slitter unit. Control is performed to cut at 320 and to be cut by the cutting unit 380, and image formation is continued (step S115 in FIG. 9). By doing as described above, even when the paper being used for image formation becomes empty, it is possible to continue without stopping image formation.

[Operation (2) of the embodiment]
Hereinafter, the operation (2) of the image forming system, the image forming control apparatus, and the image forming system control method of the present embodiment will be described according to the operation procedure. Note that the operation (2) of this embodiment may be performed by the control unit 101 as a main body, and the control unit 301 of the sheet processing apparatus 300 is not limited thereto. Judgment and control may be performed as a main body, or a control unit (not shown) in the information processing apparatus connected to the image forming system may perform similar control. In the following description of the operation, a specific example is given of the case where the control unit 101 performs determination and control mainly.

  Further, since the operation (2) of this embodiment has a part in common with the operation (1) of the embodiment already described with reference to the flowchart of FIG. 9, the same process is given the same step number in FIG. With reference to a flowchart, it demonstrates centering on a different point.

  The control unit 101 that has received the out-of-paper information from the paper supply unit 105 because the paper in the tray being fed becomes empty during image formation, starts control according to the flowchart shown in FIG. 14 (in FIG. 14). Start).

  First, the control unit 101 performs a tray switching determination process (step S101 in FIG. 14).

  Here, the determination result of the tray switching determination process (step S101 in FIG. 14) can be continued by switching to another tray / different size paper (“continuation of different size paper can be continued” in step S102 in FIG. 14). The number of different size sheets used is equal to or less than the setting (YES in step S107 in FIG. 14), tray switching is also permitted (YES in step S108 in FIG. 14), and the peripheral area as waste ends the job. If the image can be accommodated in the accommodating unit 395 (YES in step S109 in FIG. 14), the control unit 101 determines whether or not the image formation being executed uses a plurality of sheets of different trays ( Step S110a in FIG. Note that image formation using a plurality of different tray sheets may be a cover sheet / a sheet other than a cover sheet, a normal sheet / insert sheet, or the like.

  Then, when the image formation being performed uses a plurality of sheets of different trays (YES in step S110a in FIG. 14), the control unit 101 leaves the remaining amount of sheets in another tray used for the image formation being performed. Is determined with reference to the remaining sheet information from the sheet feeding unit 105 (step S110b in FIG. 14). The remaining amount is determined by comparing the number of sheets scheduled to be used for image formation during execution with the number of sheets stored in another tray.

  When the image formation being performed does not use a plurality of sheets of different trays (NO in step S110a in FIG. 14), the control unit 101 compares with the number of sheets scheduled to be used for the image formation being performed. If it can be determined that the remaining amount of paper in another tray is sufficient (YES in step S110b in FIG. 14), the process returns to the accounting change occurrence determination process (step S111 in FIG. 14) already described in operation (1).

  On the other hand, when the image formation being performed uses a plurality of different tray sheets (YES in step S110a in FIG. 14), the control unit 101 compares the number of sheets scheduled to be used with the image formation being performed. If it is determined that the remaining amount of paper in another tray is not sufficient (YES in step S110b in FIG. 14), it is expected that the paper will also run out in the other tray and the image forming operation may be interrupted. A display screen (see FIG. 15) for prompting replenishment of the paper size that allows the job to be continued in the tray that has run out of paper and another tray in which the remaining amount of paper is insufficient is displayed on the operation display unit 103 (step S103 in FIG. 14). Image formation is interrupted until paper is replenished to the tray out of paper and another tray with insufficient paper remaining, and image formation is resumed after paper replenishment (step S104 in FIG. 14).

  In the operation display screen 103G in FIG. 15, the message screen 103Gg shows that the paper has run out, and prompts the user to replenish paper. And a second message screen 103Gg11b that prompts the user to replenish paper.

  Therefore, the operator supplies paper to the tray that is out of paper and also supplies paper to another tray that is used in the same job, so that the other types of paper are scheduled to run out. Therefore, it is possible to prevent out of paper on the other tray side, and it is possible to continue image formation while contributing to productivity by reducing the number of times of paper replenishment, which contributes to improvement of productivity. it can.

  In FIG. 15, a third message screen 103Gg13 indicating that it is possible to continue even when a large-size sheet is replenished as described in FIG. 11 may be displayed.

[Operation (3) of the embodiment]
Hereinafter, the operation (3) of the image forming system, the image forming control apparatus, and the image forming system control method of the present embodiment will be described according to the operation procedure. In the following description of the operation, a specific example is given of the case where the control unit 101 performs determination and control mainly.

  Here, a first example of the control of the image forming position and the cut position at the time of CD differential paper cut will be described with reference to FIG.

  First, the control unit 101 obtains specification information of the slitter unit 320 (information on the minimum width that can be cut by the slitter unit 320, information on whether the blades on both sides can be individually driven, etc.) (step S301 in FIG. 16). The specification information of the slitter unit 320 may be obtained by communication between the control unit 101 and the control unit 301 of each unit when the image forming system is turned on, or processing in the slitter unit 320 is required. At that time, specification information may be requested from the control unit 101 via the control unit 301.

  Here, if the blades 320a and 320b (see FIG. 4) on both sides of the slitter unit 320 that cuts the peripheral area along the sheet conveyance direction can be individually adjusted in the conveyance orthogonal direction (YES in step S302 in FIG. 16). ), The image forming unit 150 is controlled so as to form an image with the one end side orthogonal to the transport direction as the reference position and being brought close to the reference position (step S303 in FIG. 16, FIG. 6A), The slitter unit 320 is controlled so as to cut the end portion on the opposite side of the reference position as a peripheral region (step S304 in FIG. 16, FIG. 6B).

  Further, when the blades 320a and 320b (see FIG. 4) on both sides of the slitter unit 320 that cuts the peripheral area along the sheet conveyance direction are not individually adjustable in the conveyance orthogonal direction (NO in step S303 in FIG. 16). Then, the image forming unit 150 is controlled so that an image is formed around the reference position with the center position in the transport direction as the reference position (step S305 in FIG. 16, FIG. 5A), and both ends of the reference position. The slitter unit 320 is controlled so as to cut the side end portion as a peripheral region (step S306 in FIG. 16, FIG. 5B).

  As described above, when the blades 320a and 320b of the slitter unit 320 can be individually adjusted, the image position and the cutting position are set to only one, and only one of the blades 320a or 320b needs to be controlled. There is.

  Next, a second example of the control of the image forming position and the cutting position at the time of CD difference paper cutting will be described with reference to FIG.

  First, the control unit 101 obtains specification information of the slitter unit 320 (such as information on the minimum width that can be cut by the slitter unit 320) (step S301 in FIG. 17). The specification information of the slitter unit 320 may be requested either when the image forming system is turned on or when processing in the slitter unit 320 becomes necessary.

  Here, if the condition of (CD direction difference / 2)> (minimum width that can be cut in the CD direction) is not satisfied (NO in step S302 ′ in FIG. 17), one end side orthogonal to the transport direction is set as the reference position, The image forming unit 150 is controlled so as to form an image in the state of being brought to the reference position (step S303 in FIG. 17, FIG. 6A), and the end opposite to the reference position is cut as a peripheral region. Next, the slitter unit 320 is controlled (step S304 in FIG. 17, FIG. 6B).

  If the condition of (CD direction difference / 2)> (CD direction cuttable minimum width) is satisfied (YES in step S302 ′ in FIG. 17), the center position in the transport direction is set as the reference position, and the reference position is set as the center. Then, the image forming unit 150 is controlled so as to form an image (step S305 in FIG. 17, FIG. 5A), and the slitter unit 320 is cut so that the ends on both ends of the reference position are cut as peripheral regions. Control is performed (step S306 in FIG. 17, FIG. 5B).

  By doing as described above, even when two cuts on both sides cannot be executed due to the minimum cuttable width due to the specifications of the slitter unit 320, the cuts can be made by combining the two cuts into one place. That is, since the difference in the CD direction is small, the cut amount is less than the minimum cut amount in the slitter unit 320, and even if the cuts on both sides in the conveying direction side in FIG. By summing up, it is possible to cut the end portion on one side in the conveyance direction in FIG.

[Operation of Other Embodiments]
In each of the embodiments described above, the control unit 101 performs various types of processing and control. However, the control unit 301 of the sheet processing apparatus 300 may mainly perform determination and control.

  A control unit (not shown) in the information processing apparatus connected to the image forming system may perform the same control. In this case, an image forming system is configured including an external information processing apparatus in addition to the image forming apparatus 100 and the sheet processing apparatus 300, and the external information processing apparatus functions as an image forming control apparatus.

  Further, in each of the above embodiments, the paper size is matched by the two-stage cutting of the slitter unit 320 as the first cut unit and the cutting unit 380 as the second cut unit. However, the present invention is not limited to this. It may not be a thing, but a cut part of one step may be sufficient, and a cut part of three or more steps may exist.
