Description

  The present invention relates to an image forming apparatus, and more particularly to job handling.

  When an image is formed on a plurality of originals in an image forming apparatus such as a copying machine, as a post-processing, each copy may be collated and stapled (staple finishing).

  In such a case, a post-processing apparatus is disposed adjacent to the image forming apparatus main body, the transfer paper discharged from the image forming apparatus main body is received by the post-processing apparatus, and the post-processing apparatus performs stapling.

  When performing such a staple finish, a limit number of recording sheets that can be stapled is determined. When the stapling finish is specified exceeding the limit number of recording sheets, there are a case where the image formation itself is stopped and a case where only the image formation is completed without performing the stapling finish.

  In addition, when there is no transfer paper having a size designated for image formation, there are cases where image formation is stopped depending on the setting of the apparatus, and image formation is continued on transfer paper of a different size. Similarly, when there is no transfer paper of the paper type designated for image formation, there are a case where image formation is stopped depending on the setting of the apparatus, and a case where image formation is continued on transfer paper of the same size and different paper types. is there.

  In such a case, in a conventional image forming apparatus, it is possible to confirm what designation is made regarding image formation at the stage where an image formation job is reserved (before execution of image formation) (patents). Reference 1). However, after image formation is completed or canceled, it can only be confirmed whether the job is completed or canceled.

That is, when an image forming job is completed, it has not been possible to confirm whether any changes have been made. Similarly, when an image forming job is canceled, it cannot be confirmed for what reason it is canceled.
JP-A-8-142454 (first page to second page, FIG. 1)

  As described above, when an image forming job is canceled, if it is not possible to confirm the reason why the image forming job is canceled, it is possible to know what setting is used to obtain an image forming output. Can not. That is, on the display screen of the job history or the like, it is possible to confirm whether the execution is completed or canceled, but the reason for changing the setting or canceling is not displayed.

  In addition, when a job is executed with the settings automatically changed as described above, the user who receives the output product knows how the output product differs from the intended one. There is a problem that you can not. Note that a change in setting may be displayed on the display unit of the image forming apparatus during execution of the job. However, when the job is completed and the next job starts to be executed, information about the job whose previous setting has been changed is no longer displayed on the display unit.

  In addition, when a job is executed with the settings automatically changed as described above, the user who receives the output product knows how the output product differs from the intended one. Since this is not possible, there is a problem that the intended output cannot be obtained even though the same (or similar) job is repeatedly executed.

  Also, if the job is executed with the settings automatically changed as described above, the output form is not intended, such as the presence or absence of stapling, the difference in transfer paper size, or paper type. It is expected that things will be difficult to find.

<Mechanical configuration and overall operation of image forming apparatus>
Next, the overall mechanical configuration and basic operation of the image forming apparatus according to the embodiment and the finisher connected thereto will be described with reference to FIG. In FIG. 2, a state in which finisher # 1 (post-processing device) 200 and finisher # 2 (loading / discharging device) 300 are connected to image forming apparatus 100 will be described as a specific example.

  In FIG. 2, a plurality of documents d with the surface of the first page of the document facing up are placed on the tray 121 of the ADF 120 capable of reading both sides of the document. When the document d is automatically fed, reading is performed with the light source 131 and the mirrors 132 to 134 fixed under the second platen glass.

  At this time, in the image reading unit 130, the original surface of the original d is irradiated by the light source 131, and the reflected light forms an image on the light receiving surface of the CCD 135 which is a photoelectric conversion means via the mirrors 132 to 134 and the imaging optical system. . Here, the image reading unit 130 is configured by the light source 131, the mirrors 132 to 134, the optical system having the imaging optical system and the CCD 135, and the optical system driving means (not shown). In FIG. 2, when the document d is placed on the platen glass with the reading surface facing downward, the optical system scans along the platen glass and performs reading.

Then, the read image data of the document d is sent from the CCD 135 to an image processing unit 140 (not shown).
When the document d is automatically fed by the ADF 120, when the first page of the document d is read, the winding operation using the roller is performed again through the reversing roller, and the image on the back side of the document is obtained. Is read by the image reading unit 120 and sent to the image processing unit 140. In this way, the document d from which the images on the front surface and the back surface are read is reversed again by the reversing roller and stacked on the paper discharge tray 122 with the front surface facing downward. The image data read by the image reading unit 120 in this manner is stored in the storage unit 170 after predetermined image processing is performed by the image processing unit 140.

  On the other hand, the transfer paper p is fed out from any of the paper feed cassettes 30 a to 30 c on which the transfer paper (transfer paper) is stacked and fed to the image forming unit 50. The transfer paper p fed to the image forming unit 50 is synchronized by a second paper feeding roller (registration roller) 32 at the entrance thereof, and then comes closer to the photosensitive drum 51.

  The size of the document is detected when the document is placed, when the document is being transported, or when the image of the document is being read, and the detected size of the document (from a plurality of paper cassettes ( When changing magnification, such as enlarging or reducing settings, select the paper cassette that contains the transfer paper that matches the size of the transfer paper after multiplying the magnification (automatic paper selection (APS)). You may have. When this APS function is operated, a suitable transfer paper p is fed out and fed in accordance with the function.

  When the image data processed by the image processing unit 140 and stored in the storage unit 170 is input to the image writing unit 40, laser light corresponding to the image data is emitted from the laser diode in the image writing unit 40 onto the photosensitive drum 51. To form an electrostatic latent image. The electrostatic latent image is developed by the developing unit 53 to form a toner image on the photosensitive drum 51.

  This toner image is transferred to the transfer paper p by the transfer section 54 below the photosensitive drum 51. Then, the transfer paper p that is pressure-bonded to the photosensitive drum 51 is separated by the separation unit 55. The transfer paper p separated from the photosensitive drum 51 enters the fixing unit 58 via the transport mechanism 57, and the toner image is fixed by heat and pressure. In the case of double-sided image formation, the back side image (second page image) is formed on the transfer paper p at this stage.

  In the case of single-sided image formation, the transfer paper p on which the toner image is fixed is used as it is or again in accordance with the output form in a post-processing device (post-processing device 200 to stacking / discharging device 300) described later. And is discharged out of the apparatus (a post-processing apparatus described later) by the discharge roller 65.

  Further, in the case of double-sided image formation, it is conveyed downward through the guide 61 and enters the reversing unit 63. Next, the transfer paper p contained in the reversing unit 63 is again fed out by the reversing roller 62 and is sent again to the image forming unit 50 via the reversing conveyance path 64.

  In the image forming unit 50 where the image formation on the back side of the original d has been completed, the toner adhering to the photosensitive drum 51 is removed by the cleaning unit 56 and charged by the subsequent charging unit 52 to prepare for the next image formation. .

  In this state, the surface of the transfer paper p (the surface on which no image is formed yet) is carried into the image forming unit 50, and an image on the surface (first page image) is formed. The transfer paper p separated from the photosensitive drum 51 by the separation unit 55 enters the fixing unit 58 again via the transport mechanism 57 and is fixed.

  As described above, the transfer paper p on which image formation on the back surface and the front surface is completed is performed as it is or again in accordance with an output form in a post-processing device (post-processing device 200 to stacking and discharging device 300) described later. And is discharged out of the apparatus (a post-processing apparatus described later) by the discharge roller 65.

  In the post-processing device 200, as post-processing specified in advance at the time of job reservation or the like, punch processing is performed at the specified position by the punch unit 210, or stapling processing is performed at the specified position by the staple unit 220.

  In the stack discharge device 300, the transfer sheets on which the image is formed by the image forming apparatus 100 are sequentially stacked on the stack discharge tray 311. In this case, as the transfer sheets are stacked, the stack discharge tray 311 gradually descends. Then, the transfer paper is loaded, and, for example, the transfer paper can be taken out after the stack discharge unit 310 (including the stack discharge tray 311) is pulled out on the front side in the vertical direction of the paper. The transfer paper that has not been stacked on the stack discharge tray 311 of the stack discharge unit 310 is discharged to the main tray 330 or the sub-tray 340.

  Here, with reference to the flowchart of FIG. 3, the operation of the image forming apparatus that forms an image in the present embodiment will be described in detail together with the operations of the post-processing apparatus (the post-processing apparatus 200 to the stack discharge apparatus 300).

  First, the control unit 101 monitors whether there is an input of image data (generation of a reservation job) from the image reading unit 130 or the printer / scanner controller 160 (S1 in FIG. 3). If image data is input (S1 in FIG. 3), the control unit 101 stores the image data in the storage unit 170 as a reserved job is generated.

  Further, the control unit 101 records the occurrence of this reserved job in the history column of the reserved job list (S2 in FIG. 3). Here, the data structure of the reserved job list is as shown in FIG. In other words, the job ID which is the serial number of the job, the job type indicating the copy job / printer job / scanner job, the status indicating reservation / operation / stop / completion, the number of copies, the number of copies at the time of image formation It includes data such as the remaining number indicating the remaining execution, the remaining time indicating the remaining time, change / interruption information indicating whether the setting has been changed or interrupted, and the reason indicating the reason for the change or interruption. Yes. Such a reserved job list is created by the control unit 101 and stored in the storage unit 170 every time a reserved job occurs.

Then, the control unit 101 determines whether the job setting satisfies the image formation executable condition for the reserved job that has occurred (S3 in FIG. 3).
Here, the job setting corresponds to the number of image forming copies, recording paper size, tray selection, post-processing mode, and the like. Here, the tray selection means a setting of which tray of the image forming apparatus to use the recording paper. Further, the post-processing mode means stapling setting, punch setting, discharge tray specification, and the like.

  Note that this execution condition determination (FIG. 3 S3) shows a detailed processing routine separately in FIG. First, the control unit 101 determines whether or not the reserved job setting is outside the range of the machine restriction specification (S1 in FIG. 4).

If the setting of the reserved job is not outside the range of the machine restriction specification (NO in S1 in FIG. 4), there is no problem with the execution of the job, and this routine is terminated (end of FIG. 4).
If the setting of the reserved job is outside the range of the machine restriction specification (YES in S1 in FIG. 4), the job cannot be executed with the setting as it is, so that “job setting is set on the image forming apparatus side as the image forming apparatus setting”. The control unit 101 checks whether or not “execute the job by changing within a possible range” (S2 in FIG. 4).

  When the setting of the image forming apparatus is “change and execute the job setting within the range possible on the image forming apparatus side” (YES in S2 in FIG. 4), the control unit 101 sets the job setting. The change is made within the possible range on the image forming apparatus side so that the job can be executed (S3 in FIG. 3).

  The change in the job setting corresponds to a change to a recording sheet of the same size or larger when the recording sheet of the selected size is cut. The change in the job setting corresponds to a change to a recording paper tray of the same size or more when the recording paper in the selected tray is cut. Further, when stapling is set for a job having a capacity exceeding the capacity, the change to stapling is applicable. In addition, when punch setting is made for a job having more than the capacity, the change to no punch corresponds.

  If the control unit 101 determines that the job setting change (FIG. 3 S3) falls within the range of the machine restriction specification (YES in FIG. 3 S4), the control unit 101 records the history of the reserved job list. The setting change content and the reason for the change are recorded in the information (S5 in FIG. 4).

  FIG. 7 shows an example of a reserved job list list display screen. Here, FIG. 7 (1) shows the contents after the setting change (change history), and FIG. 7 (2) shows the reason for the setting change. Here, the job of ID = 0011 indicates that the staple sort has been changed to a normal sort without stapling due to the excess of the number (capability). For the job with ID = 0012, the set A4 size recording paper is cut, and thus it is changed to an A3 size recording paper of equal or higher quality.

  On the other hand, when the setting of the image forming apparatus is not “executed by changing the job setting within the range possible on the image forming apparatus side” (NO in FIG. 4), or the change of the job setting (FIG. 4). If it does not fall within the range of the machine restriction specification even after 3S3) (NO in S4 in FIG. 3), the control unit 101 deletes the input reserved job (S6 in FIG. 4).

  Here, when the job setting change (FIG. 3 S3) does not fall within the mechanical limit specification range (NO in FIG. 3 S4), the recording paper of the size selected in the job is cut. This is the case when there is no recording paper of the same size or more in another tray. In addition, when the recording paper of the tray selected in the job is cut, a case where there is no recording paper tray of the same size or more is also applicable.

  When the job is deleted in such a job (S6 in FIG. 3), the control unit 101 records the deletion history and the reason for deletion in the history information of the reserved job list (S7 in FIG. 4). FIG. 7 shows an example in which the job with ID = 0015 is deleted because there is no recording paper having a selected size or larger.

  When the job setting is changed and the history is recorded (S5 in FIG. 4), and when the job is deleted and the history is recorded (S7 in FIG. 4), the control unit 101 updates the display of the reserved job list. (S8 in FIG. 4), the executable condition determination subroutine is terminated, and the process returns to the main routine in FIG.

  Here, when the control unit 101 determines that the job setting satisfies the machine restriction specification and can be executed by the above executable condition determination (YES in S4 in FIG. 3), the control unit 101 is the oldest of the reserved jobs. Things are executed (FIG. 3, S5, S6). When the execution of the job is completed (YES in FIG. 3 S6), the control unit 101 records the completed job in the history of the past job list (S7 in FIG. 3).

For the past job list recording (S7 in FIG. 3), a detailed processing routine is separately shown in FIG.
First, when the execution of the reservation job recorded in the reservation job list described above is completed and the next reservation job is being executed, the control unit 101 displays the history of the job that has been executed as a reservation job list. And the job information is registered in the past job list (S1 in FIG. 5), and the job history information is registered (S2 in FIG. 5).

  FIG. 8 shows an example of a past job list list display screen. Here, the job information corresponds to basic job information (job ID, status, number of copies, number of copies, total number of copies, time, etc.), and job history information is a change history newly adopted in the present embodiment. The reason is information (FIGS. 8 (1) and (2)).

  Here, for the job with ID = 0011, the stapling sort is changed to the normal sorting without stapling for the reason of exceeding the number of sheets (capability) and executed. The job with ID = 0012 represents that the set A4 size recording sheet was cut and changed to an A3 size recording sheet equal to or greater than that and executed. Here, the job of ID = 0013 represents that the job was deleted and the execution was canceled due to the reason for exceeding the number of sheets. The job with ID = 0014 indicates that the execution has been completed without any change.

  The reserved job list and the past job list created by the control unit 101 as described above are stored in the storage unit 170, and the control unit 101 displays the display unit when a predetermined call operation is performed from the operation unit 111. 112 may be displayed as a dedicated screen.

  When a reservation job is input, a determination may be made at the time of input, and the change contents may be displayed in a pop-up on the normal screen of the display unit 112. In addition, the change content or the like may be displayed in a pop-up on the normal screen of the display unit 112 when the reservation job starts execution. Further, when the execution of a job is completed and the execution of the next job is started, the latest contents of the past job list (the contents of the job immediately after the completion of execution) and the like may be displayed in a pop-up on the normal screen of the display unit 112. .

  In addition, the reserved job list and the past job list created by the control unit 101 as described above are stored in the storage unit 170, and when a predetermined call operation is performed from another network-connected computer. It may also be displayed on the display screen of the computer that performed the call operation.

  As a result, according to this embodiment, it is possible to clarify the changed settings for a job executed by changing the settings before the job is executed, during the job execution, and after the job execution. For this reason, it is possible to prevent a situation in which a transfer sheet is wasted by repeatedly executing a job having the same setting.

  In addition, when a job is executed with the settings automatically changed as described above, the output form may not be intended, such as the presence or absence of stapling, transfer paper size, or paper type. Even if it exists, it becomes possible to easily find the output by referring to the past job list.

  In this embodiment, since the job setting does not satisfy the image formation executable condition, even when the setting change is attempted, the job cannot be executed but the job is canceled. By displaying the list and the past job list, it is possible to clarify the settings for jobs that cannot be executed even if the settings are changed. Therefore, it is possible to prevent a situation in which time is wasted by repeatedly executing a job having the same setting.

  In this embodiment, post-change settings for jobs that are executed after changing post-processing settings, or settings for jobs that cannot be executed even if post-processing settings are changed, are executed before job execution. It can be revealed during or after job execution.

  Further, in this embodiment, since the selection is changed for a plurality of paper feed trays that respectively store transfer papers of different sizes or paper types, a job executed by changing the paper feed tray setting is executed. The settings after the change or the settings for the job that cannot be executed even if the paper feed tray setting is changed can be made clear before the job is executed, during the job execution, or after the job execution.

  Note that if the job setting is changed for a reason other than the specific example shown in the above embodiment or the job execution is canceled, the change contents and the reason are displayed as in the above specific example. It becomes possible to clarify before, during, and after job execution.
