  FIG. 3 is an explanatory diagram related to display on the display panel of the operation unit 106 in the present embodiment. The display panel is divided into a screen display area 301 and a status line 302. In the screen display area 301, a menu screen and function screens corresponding to functions such as copy and fax are displayed. Status information is displayed on the status line 302. As described above, the display panel of the image forming apparatus 1 of the present embodiment is provided with the area (status line 302) in which information independent of the basic screen transition is displayed. The screen display area 301 is an example of the first area. The status line 302 is an example of the second area. The second region may be a region different from the first region as long as it is a display region that is not interlocked with the display content of the first region, and the position, shape, and size of the second region are not limited to those in the embodiment. Not something.

  FIG. 4 is a diagram showing an example of a login screen 401 displayed on the display panel. From the viewpoint of security, the image forming apparatus 1 can set whether or not the user is required to authenticate before using the image forming apparatus 1. The login screen 401 is displayed before use when the authentication setting is valid. If the authentication setting is invalid, the login screen 401 is not displayed. The login screen 401 has an area for the user to input his / her authentication information. In the example of FIG. 4, input fields for the user name and password are displayed.

  The status line 302 also displays information 402 that should be called to the user. Examples of the information to be evoked include that the toner for printing and the remaining amount of paper are small. The display area of the status line is basically limited. Therefore, when there is more than one piece of information to be evoked, if the information cannot be displayed at one time, the display content can be automatically switched and displayed at regular time intervals (for example, 2 seconds). A status line display list is stored in the RAM 102. It is assumed that the status line display list is provided with a plurality of cells capable of storing a plurality of pieces of information to be displayed on the status line. When a plurality of pieces of information are stored in the status line display list, the CPU 101 can sequentially switch display contents on the status line by sequentially referring to cells.

  FIG. 5 is a diagram showing an example of a screen displayed on the display panel. A menu screen 501 is shown in FIG. A copy screen 511 is shown in FIG. As described above, the information 502 to be called and the status confirmation button 503 are displayed on the status line 302 regardless of the display content of the screen display area 301. When the status confirmation button 503 is pressed, a job history screen described later is displayed. Further, after the user logs in to the image forming apparatus 1, the status line 302 displays information according to the logged-in user. For example, assume that the print job instructed by the logged-in user is canceled. In this case, as shown in FIG. 5C, the status line 302 displays notification information 531 for notifying the user that the print job has been canceled, such as “There is a canceled job.” It

  FIG. 6 is a diagram showing the job history screen 601. The job history screen 601 displays an outline of each job. In the example of FIG. 6, the time when the job is accepted, the job owner, the job type, and the end status are displayed. When a job is selected on the job history screen 601, a job detail screen 701 shown in FIG. 7 is displayed. On the job history screen 601, a button 602 is a “return” button to the previous screen, and it is possible to return to the previous screen by pressing the button. The job details screen 701 shown in FIG. 7 displays detailed information related to the selected job. That is, the job details screen 701 displays more information in addition to the information displayed on the job history screen 601. The button 702 is a “return” button to the previous screen.

  FIG. 8 is a flowchart showing the job history recording process. The job control unit 201 starts the job history recording process when the image forming apparatus 1 is powered on. In step S801, the job control unit 201 determines whether a print job has been accepted. The job control unit 201 maintains a job reception waiting state until a print job is received. When the job control unit 201 receives a print job (YES in S801), the process advances to S802. In step S <b> 802, the job control unit 201 determines whether an error has occurred at each stage of print processing. Here, the error is a situation in which the print processing cannot be continued, and examples thereof include a case where the received data is invalid or a case where the work memory necessary for the print processing cannot be secured. If an error has occurred (YES in S802), job control section 201 advances the process to S803. If no error has occurred (NO in S802), the job control unit 201 advances the process to S805.

  In step S803, the job control unit 201 stores the cancellation information in the status line display list. Here, the cancellation information is information in which the identification information of the print job in which the error has occurred and the identification information of the job owner are associated with each other. Here, the job owner is the user who has submitted the print job. The status line display list is stored in the RAM 102. In step S804, the job control unit 201 performs print job cancel processing, and then advances the processing to step S806. In the cancel processing, the job control unit 201 sets a value indicating “cancellation due to an error in which printing cannot be continued” to the end status of the print job. On the other hand, in step S805, the job control unit 201 controls to execute print processing. Then, when the print process is completed, the job control unit 201 sets a value indicating “print completed” to the end status of the print job. After that, the job control unit 201 advances the processing to S806.

  In step S806, the job control unit 201 stores job information corresponding to the print job in the job history list. Here, the job information includes the identification information of the print job and the end status. The job control unit 201 then advances the process to S801. The job history list is stored in the RAM 102. The UI processing unit 202 displays the job history screen 601 (FIG. 6) by referring to the job history list.

  As described above, when the print job is canceled due to the error that the printing cannot be continued, the job control unit 201 indicates that the print job is canceled in association with the print job. Store information. That is, the job control unit 201 stores information indicating that the print job is canceled when the print job is automatically canceled without an instruction from the user.

  FIG. 9 is a flowchart showing the status line display processing. The UI processing unit 202 starts the status line display processing when the image forming apparatus 1 is powered on. The status line display processing is executed in parallel with the job history recording processing. In step S901, the UI processing unit 202 selects the head cell of the status line display list as a processing target. Next, in step S902, the UI processing unit 202 confirms the information stored in the processing target cell. In the case of the cancellation information (cancellation information in S902), the UI processing unit 202 advances the process to S903. In the case of other information (others in S902), the UI processing unit 202 advances the processing to S905. Here, the other information is information other than the cancellation information among the information to be urged to the user.

  In step S903, the UI processing unit 202 determines whether the login user is the job owner. The UI processing unit 202 determines that the login user is the job owner when the identification information of the job owner included in the cancellation information matches the identification information of the login user. If the logged-in user is the job owner (YES in S903), UI processing unit 202 advances the process to S904. If the login user is not the job owner (NO in S903), the UI processing unit 202 advances the process to S906. When the authentication setting of the image forming apparatus 1 is invalid, the UI processing unit 202 always determines that the same in S903. Further, as in the case where the login screen 401 shown in FIG. 4 is being displayed, in the state before the user logs in, the UI processing unit 202 determines that the logged-in user is not the job owner.

  In step S904, the UI processing unit 202 displays notification information for notifying that the print job has been canceled on the status line 302, as illustrated in FIG. The UI processing unit 202 then advances the process to S906. In step S905, the UI processing unit 202 displays the content of the cell on the status line. In this case, the status line 302 displays information other than the notification information indicating that the print job has been canceled, such as the information 502 shown in FIG. 5B. The UI processing unit 202 then advances the process to S906. In step S906, the UI processing unit 202 changes the cell to be processed by advancing the index of the status line display list by one. Note that the status line display list has a circular list structure, and when the cell being selected is at the end of the list, the index returns to the head and the head cell becomes the selection target. The UI processing unit 202 advances the process to S902 after the process of S906.

  FIG. 10 is a flowchart showing the cancellation information deletion process. The UI processing unit 202 starts the cancellation information deletion process when the image forming apparatus 1 is powered on. That is, the cancellation information deletion process is executed in parallel with the status line display process and the job history recording process.

  In step S1001, the UI processing unit 202 determines whether the status confirmation button 503 has been pressed. Here, the status confirmation button 503 is a button for receiving a display instruction of the job history screen 601. When the status confirmation button 503 is selected and the display instruction is accepted (YES in S1001), the UI processing unit 202 advances the process to S1002. In step S1002, the UI processing unit 202 selects the head cell of the status line display list as a processing target. Next, in step S1003, the UI processing unit 202 confirms the information of the processing target cell. In the case of cancellation information (cancellation information in S1003), the UI processing unit 202 advances the process to S1004. The UI processing unit 202 advances the process to S1006 in the case of other information than the cancellation information (others in S1003).

  In step S1004, the UI processing unit 202 determines whether the identification information of the login user is the same as the identification information of the job owner included in the cancellation information of the processing target cell. If the identification information of both is the same (YES in S1004), the UI processing unit 202 advances the process to S1005. If the identification information of the both is not the same (NO in S1004), the UI processing unit 202 advances the process to S1006. Note that when the authentication setting of the image forming apparatus 1 is invalid, the UI processing unit 202 always determines to be the same in step S1004.

  In step S1005, the UI processing unit 202 deletes the cancellation information stored in the processing target cell from the status line display list. Next, in step S1006, the UI processing unit 202 confirms whether or not the cell being selected as a processing target is at the end of the status line display list. If the tail end (YES in S1006), the UI processing unit 202 advances the process to S1001. If it is not at the end (NO in S1006), the UI processing unit 202 advances the process to S1007. In step S1007, the UI processing unit 202 changes the processing target cell by advancing the index of the status line display list by one, and then advances the process to step S1003.

  When the job history screen is displayed, it can be judged that "the user has recognized the job by looking at the status line and has displayed the job history screen to confirm the cause of the job cancellation". it can. In response to this, the image forming apparatus 1 according to the present embodiment deletes the cancellation information on the condition that the job history screen is displayed. Thus, the notification information is not displayed after the job history screen is displayed.

  As described above, when the canceled job exists, the image forming apparatus 1 according to the present embodiment indicates that the canceled job exists regardless of the screen transition of the first area of the display panel. The notification information can be displayed in the second area. That is, in the image forming apparatus 1, it is possible to display that there is a canceled job without requiring a user operation such as displaying a list of jobs. In this way, the image forming apparatus 1 can notify that the canceled job exists without requiring a special operation by the user.

(Second embodiment)
Next, with respect to the image forming apparatus 1 according to the second embodiment, differences from the image forming apparatus 1 according to the first embodiment will be mainly described. The image forming apparatus 1 according to the present embodiment automatically cancels a suspended job from the viewpoint of usability and the like when the job is suspended for some reason and the suspended state continues for a certain period of time.

  FIG. 11 is a flowchart showing the job history recording process according to the second embodiment. In step S1101, the job control unit 201 determines whether a print job has been accepted. The job control unit 201 maintains the job reception waiting state until the print job is received, and when the print job is received (YES in S1001), the process proceeds to S1102. In step S1102, the job control unit 201 confirms at each stage of the printing process whether or not an error that requires interruption of the process has occurred. In addition, about the error which must interrupt a process, it shall be preset. The errors that must be interrupted are all errors that can be corrected by the user's response, for example, there is no toner or paper for printing, or a paper jam has occurred in the image forming device during printing. , And the like. The job control unit 201 advances the process to S1103 when an error that must be interrupted occurs (YES in S1102). The job control unit 201 advances the process to S1108 when the error that should be interrupted has not occurred (NO in S1102).

  In step S1103, the job control unit 201 starts a timer for determining whether or not the interruption duration has reached the waiting time until the automatic cancellation. The waiting time until the automatic cancellation (until the timer expires) is a time preset by the user. Next, in step S1104, the job control unit 201 confirms whether or not the interruption factor has been resolved. When the job control unit 201 is canceled (YES in step S1104), the job control unit 201 stops the timer, restarts the print processing, and advances the processing to step S1102. The job control unit 201 advances the process to S1105 if not canceled (NO in S1104).

  In step S1105, the job control unit 201 confirms whether the timer has expired. When the job control unit 201 ends (YES in S1105), the job control unit 201 stops the timer and advances the process to S1106. If not completed (NO in S1105), the job control unit 201 advances the process to S1104. The processing of S1107 following S1106 and S1106 is the same as the processing of S803 and S804 described with reference to FIG. 8, respectively. The processing of S1108 and S1109 is the same as the processing of S805 and S806, respectively. The other configurations and processes of the image forming apparatus 1 according to the second embodiment are the same as the configurations and processes of the image forming apparatus according to the first embodiment.

(Third Embodiment)
Next, the differences between the image forming apparatus 1 according to the third embodiment and the image forming apparatus 1 according to the other embodiments will be mainly described. The image forming apparatus 1 according to the present embodiment deletes the notification information from the status line display list triggered by the display of the job detail screen 701 for the canceled print job.

  FIG. 12 is a flowchart showing the cancellation information deletion process according to the third embodiment. In step S1201, the UI processing unit 202 determines whether the status confirmation button 503 has been pressed. When the status confirmation button 503 is pressed (YES in S1201), the UI processing unit 202 advances the process to S1202. In step S1202, the UI processing unit 202 controls to display the job history screen 601. Next, in step S1203, the UI processing unit 202 receives a user operation. When the user selects an arbitrary print job on the job history screen 601, the UI processing unit 202 advances the process to S1204 (select an arbitrary job in S1203). If the user presses the return button 602 (return in S1203), the UI processing unit 202 changes the display on the display panel to the previous screen, and then advances the processing to S1201.

  In step S1204, the UI processing unit 202 controls to display the job detail screen 701 of the selected print job. The UI processing unit 202 further selects the top cell of the status line display list as a display target. Next, in S1205, the UI processing unit 202 confirms the information of the processing target cell. In the case of cancellation information (cancellation information in S1205), the UI processing unit 202 advances the process to S1206. In the case of other information (others in S1205), the UI processing unit 202 advances the process to S1208.

  In step S1206, the UI processing unit 202 determines whether the identification information of the login user and the identification information of the job owner included in the cancellation information of the processing target cell are the same. The UI processing unit 202 further determines whether the identification information of the print job corresponding to the currently displayed job detail screen and the identification information of the print job included in the cancellation information are the same. If the authentication setting of the image forming apparatus 1 is invalid, the identification information of the login user is always determined to be the same. If both the login user identification information and the print job identification information are the same (YES in S1206), the UI processing unit 202 advances the process to S1207. If at least one of the identification information of the login user and the identification information of the print job is not the same, the UI processing unit 202 proceeds to S (NO in S1206), and advances the processing to S1208. In step S1207, the UI processing unit 202 deletes the cancellation information stored in the processing target cell from the status line display list, and then the process proceeds to step S1210.

  In step S1208, the UI processing unit 202 confirms whether or not the cell being selected as the processing target is at the end of the status line display list.
