Description

  The present invention relates to an image forming system that forms an image on paper such as a printer or a light printing apparatus, performs post-processing, and outputs the image, and an image forming control program for controlling the image forming system.

  A digital printing system using an electrophotographic image forming system is used in the field of production printing. In this type of image forming system, a reading unit is arranged on the downstream side of the image forming unit, and printing abnormality detection (hereinafter, sag detection) of printed matter is performed from an image obtained by reading a sheet after image formation. It has been broken. As the reading unit, various imaging devices such as an inline sensor and a CCD camera can be used. In addition, there is a technology that warns of an abnormality for a sheet in which an abnormality is detected and displays a sheet to be removed.

By the way, if the output is a booklet-like printed matter, productivity will be significantly reduced by stopping the output when an image abnormality is detected, removing the paper where the abnormality is detected, and continuing printing. There is a problem.
On the other hand, there is a technique in which printing is continued in order to prevent a decrease in productivity, and a booklet including an abnormal image is visually removed after completion. In the case of this method, there is a problem that it takes time and effort to inspect and remove a booklet in which an abnormal image is mixed, and there is also a possibility that a booklet containing the abnormal image may be distributed as a product due to oversight.

In the case of confidential printing, it may not be preferable to check the contents of a document in order to remove abnormal images.
Various proposals have been made in the following patent documents for these techniques.

[Operation (1)]
Hereinafter, the operation of the basic first embodiment will be described with reference to the flowchart of FIG. Here, the operation in the image forming system 1 of FIGS. 1 and 2 is taken as a specific example.
In the image forming apparatus 100, various initial settings relating to image formation are executed (step S11 in FIG. 5).

As a part of this initial setting, the control unit 101 may accept selection of another post-processing candidate executed when an abnormality is detected in image formation from the user via the operation display unit 103. It should be noted that another post-processing candidate may be determined in advance.
Here, when a state (output form) obtained by performing post-processing designated in image formation (“designated post-processing”) on the paper is “first state”, the paper is different from the first state. Post-processing for realizing the output form (hereinafter “second state”) is referred to as “separate post-processing”.

  For example, when the post-designation process is upper left stapling, the post-separation process is two-point stapling. When the post-designation process is saddle stitching, the post-separation process is overlapped and folded. For example, saddle stitching, when the post-designation process is punching, another post-processing is punching in which the hole position is half the outside of the sheet. Moreover, in order to implement | achieve a 2nd state, post-process non-execution, post-process incomplete execution, etc. may be included as another post-process. Note that “post-processing non-execution” in which post-processing is not executed is treated as a kind of “separate post-processing” in this embodiment.

  Then, the control unit 101 performs the image formation instructed by the operation display unit 103 or the externally connected device, so that the paper feeding unit 105, the transport unit 107, the image data storage unit 130, the image processing unit 140, and the image forming unit 150 are executed. Then, the fixing unit 160 is controlled (step S12 in FIG. 5). That is, upon receiving an instruction to start image formation, the control unit 101 feeds a sheet from the sheet feeding unit 105 toward the image forming unit 150, and performs image processing on the image data read from the image data storage unit 130. The image processing is executed in step S1, the image forming unit 150 forms an image on the sheet, and the fixing unit 160 controls each unit so that the image is stabilized by heat and pressure.

Then, the control unit 101 performs control so that the sheet on which the image is formed in this way is conveyed from the image forming apparatus 100 toward the intermediate apparatus 200.
The control unit 101 controls the output material reading unit 290 via the control unit 201 so that the output material reading unit 290 reads the image on the sheet (step S13 in FIG. 5). Image data (read image data) obtained by the output material reading unit 290 is sent to the control unit 101 via the communication unit 202 and the communication unit 201. Then, the control unit 101 determines whether there is an abnormality in the read image data by a known method (step S14 in FIG. 5). This abnormality determination is performed by the control unit 101, for example, by comparing the print image data for image formation held in the image data storage unit 130 with the read image data.

  Here, if no abnormality is detected on any of a plurality of sheets from the start page to the last page of image formation (NO in step S15 in FIG. 5), the bundle of the plurality of sheets is detected. In response to the instruction from the control unit 101, the control unit 301 controls the post-processing unit 330 to execute the original post-processing (designated post-processing) specified for image formation (step S17 in FIG. 5). .

  On the other hand, if an abnormality is detected in any of a plurality of sheets from the start page to the last page of image formation (YES in step S15 in FIG. 5), a bundle of the plurality of sheets is detected. The control unit 101 determines whether post-processing is designated (step S16 in FIG. 5).

  Here, if the post-processing in the image formation that is being executed is a designation for a bundle of a plurality of sheets (YES in step S16 in FIG. 5), a bundle of a plurality of sheets is designated. In response to the instruction from the control unit 101, the control unit 301 controls the post-processing unit 330 to execute another post-processing instead of the designated post-processing (step S18 in FIG. 5).

  Upon receiving an instruction from the control unit 101, the control unit 301 receives a plurality of sheets in a bundle unit (step S 17 in FIG. 5) on which post-designation processing has been performed by the post-processing unit 330. Post-processing is canceled when a plurality of sheets in a bundle unit that has been processed (step S18 in FIG. 5) or when post-processing is not specified in bundle units (NO in step S16 in FIG. 5). The plurality of sheets are controlled to be discharged to any one of the paper discharge trays of the paper discharge unit 390 (step S20 in FIG. 5).

[Effect obtained by operation (1)]
As described above, a bundle of a plurality of sheets determined to be normal based on the reading result is set to the first state by the post-designation process, and a plurality of sheets including a sheet determined to be abnormal based on the reading result is included. By controlling the post-processing so that the output form is set to the second state by separate post-processing, the output form of the normal sheet and the output form including the abnormal sheet are different from each other. Therefore, it is possible to output an output including an abnormal sheet in a state where it can be easily distinguished from a normal output. In other words, it prevents the output material including abnormal paper from being mixed into the printed material designated as a part or bundle of staples, booklets, glue binding, etc., and greatly reduces the trouble of detecting an abnormal output material. can do. In addition, since the difference between the first state and the second state can be made by tactile sense, work can be performed even if the person is not an expert. Further, since it is possible to identify the appearance without confirming the content, the content of the confidential print does not leak outside. As described above, since the output form of the sheet bundle by post-processing is changed depending on whether it is normal or abnormal, even if the sheets are discharged on the same discharge tray, Can be output in a state where it can be easily identified.

[Operation (2)]
The operation of the second embodiment will be described below with reference to the flowchart of FIG. Here, the operation in the image forming system 1 of FIGS. 1 and 2 is taken as a specific example. In FIG. 6 describing the second embodiment, the same processing as in FIG. 5 described in the first configuration example is assigned the same step number, and redundant description is omitted.

In the image forming apparatus 100, initial setting (step S11 in FIG. 6), image formation (step S12 in FIG. 6), reading (step S13 in FIG. 6), abnormality determination based on the control of the control unit 101. (Step S14 in FIG. 6) is executed.
Here, if no abnormality is detected on any of the plurality of sheets (NO in step S15 in FIG. 6), the control unit 101 performs the designated post-processing on the bundle of the plurality of sheets. The control unit 301 that receives the instruction from the control unit controls the post-processing unit 330 (step S17 in FIG. 6).

  On the other hand, if an abnormality is detected in any of a plurality of sheets from the start page to the last page of image formation (YES in step S15 in FIG. 6), a bundle of the plurality of sheets is formed. If post-processing is designated (YES in step S16 in FIG. 6), sheets after the sheet in which the abnormality is detected (sheets up to the last page belonging to the same bundle as the sheet in which the abnormality is detected). The control unit 101 adds another post-process that can be executed for each sheet of paper (step S19 in FIG. 6), and further executes the specified post-process for the bundle of the plurality of sheets. Upon receiving the instruction, the control unit 301 controls the post-processing unit 330 (step S17 in FIG. 6).

In this case, for example, post-processing such as punch holes is added to the paper after the abnormality is detected, and case binding processing is executed as post-designation post-processing for each bundle unit.
Upon receiving an instruction from the control unit 101, the control unit 301 receives a plurality of sheets of normal bundle units that have undergone designated post-processing (NO in step S15 in FIG. 6, step S17). A plurality of sheets subjected to separate post-processing in units of one sheet and further subjected to designated post-processing in units of bundles (YES in step S15 in FIG. 6, YES in step S16, step S19, step S17), or bundle When no post-processing is designated in units (NO in step S16 in FIG. 6), control is performed so that a plurality of sheets whose post-processing is stopped are discharged to one of the paper discharge trays of the paper discharge unit 390. (Step S20 in FIG. 6).

[Effect obtained by operation (2)]
As described above, a bundle of a plurality of sheets determined to be normal based on the reading result is set to the first state by the post-designation process, and a plurality of sheets including a sheet determined to be abnormal based on the reading result is included. For bundles, the post-processing is performed so that the output form is set to the second state by adding another post-processing after the abnormal paper and then performing the designated post-processing, so that the post-processing state is applied to the output matter including the abnormal paper. Is maintained in the second state until reaching the final sheet of the set, it is possible to output a bundle of output materials including the abnormal sheet in a state where it can be easily identified. In other words, it is possible to prevent the output material including the abnormal paper from being mixed into the designated printed material, and to greatly reduce the trouble in detecting the abnormal output material. In addition, since the difference between the first state and the second state can be made by tactile sense, work can be performed even if the person is not an expert. Further, since it is possible to identify the appearance without confirming the content, the content of the confidential print does not leak outside. As described above, since the output form of the sheet bundle by post-processing is changed depending on whether it is normal or abnormal, even if the sheets are discharged on the same discharge tray, Can be output in a state where it can be easily identified.

The operation of the third embodiment will be described below with reference to the flowchart of FIG. Here, the operation in the image forming system 1 of FIGS. 1 and 2 is taken as a specific example. In FIG. 7 illustrating the third embodiment, the same processing as in FIG. 5 described in the first configuration example is assigned the same step number, and redundant description is omitted.

  In the image forming apparatus 100, various initial settings relating to image formation are executed by the control unit 101. As a part of this initial setting, the control unit 101 receives a selection of another post-processing candidate to be executed when an abnormality is detected in image formation from the user via the operation display unit 103 (step S11 in FIG. 7). '). In the third embodiment, the post-processing candidate is a second state candidate (second state candidate) as a paper output form.

At this time, the control unit 101 displays the other post-processing candidate selection screen 103G1A in FIG. 8 or the other post-processing candidate selection screen 103G1B in FIG. The selection of another post-processing is accepted from.
Here, another post-processing candidate selection screen 103G1A in FIG. 8 shows a state in which Z-folding (outside tri-fold) at x1 and 2-hole punch left at x2 are selected as other post-processing candidates at the time of abnormality detection. Yes. In this case, the selected other post-process is executed (step S18 in FIG. 7) within a range that does not overlap with the post-designation process (step S17 in FIG. 7).

  In addition, on the other post-processing candidate selection screen 103G1B in FIG. 9, the z-fold of x1 and the 2-hole punch left at x2 are selected as other post-processing candidates at the time of abnormality detection, and the z-fold of x1 ′ is the first priority. The x2 ′ two-hole punch left is selected as another post-processing candidate with priority setting with the second priority. In this case, within a range that does not overlap with the designated post-process (step S17 in FIG. 7), another post-process selected in advance (see FIG. 8) or another post-process selected in advance and having a high priority (FIG. 8). 9), another post-process is selected and executed (step S18 ′ in FIG. 7).

By notifying the user, the state of the output matter including the abnormal sheet can be easily recognized.

[Operation (5)]
The operation of the fifth embodiment will be described below with reference to the flowchart of FIG. Here, the operation in the image forming system 1 of FIGS. 1 and 2 is taken as a specific example. In FIG. 13 for explaining the fifth embodiment, the same processing as in FIG. 5 explained in the first configuration example is given the same step number, and redundant explanation is omitted.

  In the image forming apparatus 100, based on the control of the control unit 101, initial setting (step S11 in FIG. 13), image formation (step S12 in FIG. 13), reading (step S13 in FIG. 13), abnormality determination The control unit 101 controls to perform (Steps S14 and S15 in FIG. 13) and bundle unit processing presence / absence determination (Step S16 in FIG. 13).

Here, if no abnormality is detected in any of the plurality of sheets (NO in step S15 in FIG. 13), the post-processing unit 330 executes designated post-processing on the bundle of the plurality of sheets. (Step S17 in FIG. 13).
If an abnormality is detected in any of a plurality of sheets (YES in step S15 in FIG. 13), and if post-processing is designated for a bundle of the plurality of sheets ( In step S16 in FIG. 13, YES in step S16, the control unit 101 and the control unit 301 confirm the post-processing setting to determine whether there is another post-process that can be executed by the post-processing unit 330 other than the designated post-process (in FIG. 13). Step S18a, Step S18b).

  Here, if there is another post-process that can be executed by the post-processing unit 330 other than the designated post-process (YES in step S18b in FIG. 13), the post-process is executed on a bundle of a plurality of sheets. As described above, the control unit 301 receiving the instruction from the control unit 101 controls the post-processing unit 330 (step S18c in FIG. 13).

  On the other hand, if there is no other post-process that can be executed by the post-processing unit 330 other than the designated post-process (NO in step S18b in FIG. 13), the post-process is not executed on a bundle of a plurality of sheets. Upon receiving the instruction from the control unit 101, the control unit 301 controls the post-processing unit 330 (step S18d in FIG. 13).

  The fact that there is no other post-process that can be executed means that there is no other post-process that can be executed as a bundle when an abnormality is detected due to the relationship between the post-designation process and the paper transport path. Further, even if the post-processing can be executed as another post-processing, if it is difficult to distinguish it from the designated post-processing as the output form, it may be handled that there is no executable post-processing.

  In this case, the output form of the bundle of sheets subjected to the designated post-processing (step S17 in FIG. 13) is in the first state, and executable separate post-processing (step S18c in FIG. 13) has been performed. If the output form of the sheet bundle is in the second state and there is no executable post-determination process, post-processing is not executed (step S18d in FIG. 13). The sheet bundle is also in the second state.

  Upon receiving an instruction from the control unit 101, the control unit 301 detects a plurality of sheets in a normal bundle unit that has undergone designated post-processing (NO in step S15 in FIG. 13, step S17), and an abnormality is detected. A plurality of sheets subjected to separate post-processing in a bundle unit (YES in step S15 in FIG. 13, YES in step S16, YES in step S18b, step S18c), and a plurality of sheets that are not subjected to post-processing when an abnormality is detected Paper (YES in step S15 in FIG. 13, YES in step S16, YES in step S18b, step S18d), or no post-processing is specified for each bundle (NO in step S16 in FIG. 13). Control is performed so that a plurality of sheets on which the operation is not performed is discharged to one of the discharge trays of the discharge unit 390 (step S20 in FIG. 13).

[Effect obtained by operation (5)]
In the above case, in addition to the effects of the operations (1) to (4) described above, when there is no other post-process that can be executed, control is performed so as to realize the second state by not executing the post-process. Thus, it is possible to output a bundle of output materials including abnormal sheets in a state where they can be easily identified.

[Operation (6)]
The operation of the sixth embodiment will be described below with reference to the flowchart of FIG. Here, the operation in the image forming system 1 of FIGS. 1 and 2 is taken as a specific example. In addition, in FIG. 14 explaining this 6th Embodiment, the duplicate description is abbreviate | omitted by attaching | subjecting the same step number to the same process as FIG. 5 demonstrated in the 5th structural example and FIG. 5 demonstrated in the 1st structural example.

The control unit 101 performs control (steps S14 and S15 in FIG. 14) and bundle unit processing presence / absence determination (step S16 in FIG. 14).

Here, if no abnormality is detected in any of the plurality of sheets (NO in step S15 in FIG. 14), the post-processing unit 330 executes designated post-processing on the bundle composed of the plurality of sheets. (Step S17 in FIG. 14).
Further, if an abnormality is detected in any of the plurality of sheets (YES in step S15 in FIG. 14), if post-processing is specified for a bundle of the plurality of sheets ( In step S16 in FIG. 14, YES in step S16, the control unit 101 and the control unit 301 determine whether there is another post-process that can be executed in addition to the post-designation process and is most different from the post-designation process. Confirm (step S18a, step S18b1, step S18b2 in FIG. 14).

  Here, if another post-process that can be executed other than the designated post-process and is the most different from the designated post-process is selected (YES in step S18b1 and YES in step S18b2 in FIG. 14), a plurality of sheets are used. In response to the instruction from the control unit 101, the control unit 301 controls the post-processing unit 330 to execute the selected post-processing for the bundle consisting of (step S18c in FIG. 14).

  On the other hand, when there is no other post-process that can be executed by the post-processing unit 330 other than the designated post-process (NO in step S18b1 in FIG. 14), or there is no other post-process that differs most from the designated post-process. (NO in step S18b2 in FIG. 14, NO in step S18b1), the control unit 301 that receives an instruction from the control unit 101 does not execute the post-processing on the bundle of a plurality of sheets. Control is performed (step S18d in FIG. 14).

Here, other post-processing that can be executed in addition to the post-designation processing and is the most different from the post-designation processing is Z-folding, Z-folding and stapling when the post-designation processing is half-folding or saddle stitching. Applicable.
Also, here, when there is no separate post-process that differs most from the designated post-processing, even if it is a post-process that can be executed as a separate post-process, the distinction from the designated post-process as the output form is not clear. It means no case. Specifically, the case of two-staple finishing and three-staple finishing is applicable.

Upon receiving an instruction from the control unit 101, the control unit 301 outputs a plurality of sheets that have been subjected to the designated post-processing or another post-processing as described above or a plurality of sheets that have not been subjected to post-processing. Control is performed so that the paper is discharged to one of the paper discharge trays 390 (step S20 in FIG. 14).
[Effect obtained by operation (6)]
In the above case, in addition to the effects of the above-described operations (1) to (5), abnormal paper is selected and executed by selecting and executing another post-processing that can obtain an output form most different from the output form by the designated post-processing. Since the output form of the output matter including the output form is the most different from the output form of the output matter of the normal paper, the output matter of the bundle including the abnormal paper can be easily output.

[Operation (7)]
The operation of the seventh embodiment will be described below with reference to the flowchart of FIG. Here, the operation in the image forming system 1 of FIGS. 1 and 2 is taken as a specific example. In FIG. 15 for explaining the seventh embodiment, the same processing as in FIG. 5 explained in the first configuration example and FIG. 14 explained in the sixth configuration example is assigned the same step number, and redundant explanation is omitted. To do.

  In the image forming apparatus 100, based on the control of the control unit 101, initialization (step S11 in FIG. 15), image formation (step S12 in FIG. 15), reading (step S13 in FIG. 15), and abnormality determination The control unit 101 performs control (steps S14 and S15 in FIG. 15) and bundle unit processing presence / absence determination (step S16 in FIG. 15).

Here, if no abnormality is detected on any of the plurality of sheets (NO in step S15 in FIG. 15), the post-processing unit 330 executes designated post-processing on the bundle of the plurality of sheets. (Step S17 in FIG. 15).
In addition, when an abnormality is detected in any of the plurality of sheets (YES in step S15 in FIG. 15), if post-processing is designated for a bundle of the plurality of sheets ( In step S16 in FIG. 15, YES in step S16, the control unit 101 and the control unit 301 confirm post-processing settings to determine whether there is another post-process that can be executed in addition to the post-designation process and has a different output form from the designated post-process. (Step S18a, Step S18b1, Step S18b2 in FIG. 15).

  If another post-process that can be executed other than the designated post-process and has a different output form from the designated post-process is selected (YES in step S18b1 and YES in step S18b2 in FIG. 15), a plurality of sheets are used. In response to the instruction from the control unit 101, the control unit 301 controls the post-processing unit 330 to execute the selected post-processing for the bundle (step S18c in FIG. 15).

  On the other hand, when there is no other post-process that can be executed by the post-processing unit 330 other than the designated post-process (NO in step S18b1 in FIG. 15), or when there is no other post-process having a different output form from the designated post-process ( In step S18b2 in FIG. 15, NO in step S18b1, and the control instructed by the control unit 101 to execute only a part of the post-designation processing in an incomplete state for a bundle of a plurality of sheets. The unit 301 controls the post-processing unit 330 (step S18e in FIG. 15).

  The fact that there is no other post-process that can be executed means that there is no other post-process that can be executed as a bundle when an abnormality is detected due to the relationship between the post-designation process and the paper transport path. Further, even if the post-processing can be executed as another post-processing, if it is difficult to distinguish it from the designated post-processing as the output form, it may be handled that there is no executable post-processing.

  In this case, the output form of the sheet bundle that has undergone the post-designation process (step S17 in FIG. 15) is in the first state, and an executable post-determination process (step S18c in FIG. 15) has been performed. When the output form of the sheet bundle is in the second state and there is no executable post-determination process, the sheet bundle for which the post-designation process is executed in an incomplete state (step S18e in FIG. 15) Two states.

  To execute post-designation processing in an incomplete state means that if post-designation processing is case binding, the post-incomplete execution post-processing will not be glued with case binding, or if post-designation processing is saddle stitching. In addition, in the post-incomplete execution post-processing, it is discharged without being folded, and in the case where the specified post-processing is stapling, the post-incomplete execution post-processing is output without folding or cutting the staple needle. . When the post-designation process is folding, it is possible to extremely weaken the folding state in the incomplete execution post-processing.

  Upon receiving an instruction from the control unit 101, the control unit 301 detects a plurality of sheets of normal bundle units that have undergone designated post-processing (NO in step S15 in FIG. 15, step S17), and an abnormality is detected. A plurality of sheets subjected to separate post-processing in units of bundles (YES in step S15 in FIG. 15, YES in step S16, YES in step S18b, step S18c), an abnormality is detected, and designated post-processing is incomplete 15 (YES in step S15 in FIG. 15, YES in step S16, YES in step S18b, step S18e), or no post-processing is specified for each bundle (step in FIG. 15). Control is performed so that a plurality of sheets that are not subjected to post-processing are discharged to one of the discharge trays of the discharge unit 390 (NO in S16) (step S20 in FIG. 15). .

[Effect obtained by operation (7)]
In the above case, in addition to the effects of the operations (1) to (6) described above, when there is no other post-process that can be executed, the specified post-process is executed in a partially incomplete state. By controlling to achieve the two states, post-processing is completed for output products with normal paper, and post-processing is not completed for output products with abnormal paper, so it is possible to easily identify output products with bundles containing abnormal paper. Can be output in the correct state.

[Operation (8)]
Hereinafter, an eighth embodiment will be described with reference to FIG. Here, the above-described separate post-processing can be realized by moving the processing position in the post-designation processing.
FIG. 16A shows a state in which the post-designation process is a two-hole punch (H1, H2). In such a case, as shown in FIG. 16B, as another post-processing, it is possible to move the two-hole punches (H1 ′, H2 ′) so as to be on the edge of the sheet. In this case, the hole of the punch is exposed at the end, and it becomes clear that another post-processing is performed from the end of the paper visually or by touch. In this case, considering the conveyance of the sheet, it is desirable to move the punch hole to the rear end in the sheet conveyance direction.

  Further, as shown in FIG. 16C, a state in which the positions of the punch holes (H1 ″, H2 ″) are moved in a part of a plurality of sheets can be set as another post-processing. Also, in both cases of FIG. 16 (b) and FIG. 16 (c), it is applicable to various multi-hole punches such as 3-hole punch, 4-hole punch, 26-hole punch, 30-hole punch in addition to 2-hole punch. Is possible.

  In addition, when a post-designation process other than punching such as stapling is performed, it is possible to execute the end-exposure punch in FIGS. 16B and 16C as another post-process. The movement of the processing position can be applied to various types of post-processing in addition to the punch hole end exposure shown here.

[Effect obtained by operation (8)]
In the above case, in addition to the effects of the operations (1) to (7) described above, by controlling the separate post-processing so that the second state appears at the end of the abnormal paper, the output product of the bundle including the abnormal paper Can be output in a readily identifiable state.

[Operation (9)]
The operation of the ninth embodiment will be described below with reference to the flowchart of FIG. Here, the operation in the image forming system 1 of FIGS. 1 and 2 is taken as a specific example. In FIG. 17 for explaining the ninth embodiment, the same processes as those in the flowcharts explained in the first configuration example to the seventh embodiment are denoted by the same step numbers, and redundant explanation is omitted.

  In the image forming apparatus 100, initial setting (step S11 in FIG. 17), image formation (step S12 in FIG. 17), reading (step S13 in FIG. 17), abnormality determination based on the control of the control unit 101. The control unit 101 performs control (steps S14 and S15 in FIG. 17) and bundle unit processing presence / absence determination (step S16 in FIG. 17).

Here, if no abnormality is detected on any of the plurality of sheets (NO in step S15 in FIG. 17), the post-processing unit 330 executes designated post-processing on the bundle of the plurality of sheets. (Step S17 in FIG. 17).
If an abnormality is detected in any of a plurality of sheets (YES in step S15 in FIG. 17), and if post-processing is designated for a bundle of the plurality of sheets ( In step S16 in FIG. 17, the control unit 101 and the control unit 301 confirm the post-processing setting to determine whether there is another post-process that can be executed by the post-processing unit 330 other than the designated post-process (in FIG. 17). Step S18a, Step S18b).

  Here, if there is another post-processing that can be executed in units of bundles other than the designated post-processing by the post-processing unit 330 (YES in step S18b in FIG. 17 (unit of bundles)), a bundle of a plurality of sheets is formed. In response to the instruction from the control unit 101, the control unit 301 controls the post-processing unit 330 to execute another post-processing (step S18c in FIG. 17).

  In addition, since the detected abnormality is close to the last page, the post-processing unit 330 cannot be changed to a separate post-process because it is close to the last page, but can be executed for each sheet. If there is another post-processing (YES in step S18b in FIG. 17 (one sheet unit)), only one sheet for which an abnormality is detected or one sheet for each sheet after the abnormality is detected. Upon receiving an instruction from the control unit 101, the control unit 301 controls the post-processing unit 330 so as to execute post-processing (step S18f in FIG. 17). If possible, the control unit 101 instructs the post-designation processing to be performed on a bundle of a plurality of sheets including sheets that have been subjected to separate post-processing for each sheet when an abnormality is detected. In response, the control unit 301 controls the post-processing unit 330 (step S18g in FIG. 6).

  On the other hand, if there is no other post-process that can be executed by the post-processing unit 330 other than the designated post-process (NO in step S18b in FIG. 17), the post-process is not executed on a bundle of a plurality of sheets. Upon receiving an instruction from the control unit 101, the control unit 301 controls the post-processing unit 330 (step S18d in FIG. 17).

  In this case, the output form of the bundle of sheets subjected to the designated post-processing (step S17 in FIG. 17) is the first state, and the separate post-processing (step S18c in FIG. 17) is performed for each bundle. When the output form of the sheet bundle is in the second state and there is no executable separate post-processing, post-processing is not executed (step S18d in FIG. 17), and the sheet bundle is also in the second state. The output state of the bundle of sheets that has undergone separate post-processing (step S18f in FIG. 17) for each sheet is the second state.

  Upon receiving an instruction from the control unit 101, the control unit 301 detects that a plurality of sheets in a normal bundle unit that has been subjected to designated post-processing (step S17 in FIG. 17), and detects that an abnormality has occurred and separates it in bundle units. A plurality of sheets that have been processed (step S18c in FIG. 17), a plurality of sheets that have not been subjected to post-processing due to an abnormality (step S18d), and a separate post-process for each sheet that has detected an abnormality A plurality of sheets (steps S18f and S18g in FIG. 17) to which the post-processing is applied, or no post-processing is specified in units of bundles (NO in step S16 in FIG. 17). Control is performed so that the paper is discharged to one of the paper discharge trays of the paper discharge unit 390 (step S20 in FIG. 17).

  Note that the post-specific processing (step S18f in FIG. 17) executed for each sheet is different from the post-designation processing. For example, after the designation such as single folding processing such as Z-folding. A process different from the process is desirable. For this reason, when an abnormality is detected near the last page, a booklet including a sheet that has been subjected to a single folding process is produced, and thus the detectability of a bundle including a sheet in which an abnormality has been detected increases. It is very easy to distinguish from a normal sheet bundle.

  In the ninth embodiment, the other post-processing executed for each sheet is not limited to the sheet for which an abnormality is detected. That is, by performing another post-processing on one of a plurality of sheets including a sheet in which an abnormality is detected, the detectability of the bundle including the sheet in which an abnormality is detected is increased, and the normal sheet Identification with a bundle becomes extremely easy.

[Effect obtained by operation (9)]
In the above case, in addition to the effects of the operations (1) to (8) described above, when an abnormal sheet appears just before the last sheet in the bundle, the process proceeds to another post-processing for the bundle unit due to the influence of the abnormality detection timing. If the change cannot be made, the post-process for each sheet is performed so as to realize the second state, so that the output of the bundle including the abnormal sheet is output in a readily identifiable state. be able to.

[Other operations]
In the above operations (1) to (9), another post-processing that realizes the second state different from the first state of the normal sheet is executed in the bundle in which the abnormality is detected. The control unit 101 controls each unit so that the bundle processing is executed as usual.
