An input device includes a touch panel and a control unit. The touch panel is configured to be switched between a normal operation mode and a special operation mode. The control unit is configured to control the touch panel. In the special operation mode, the control unit is configured to: generate a special-operation-mode-based input portion based on a continuous contact with the touch panel; and accept a release of the continuous contact with the touch panel as an input to the special-operation-mode-based input portion.

An image processing apparatus having functions includes an image processing unit that executes the functions; a memory that stores a function table including function identification information identifying the functions, initial values preset for the functions, and registered values set for the functions by a user, in a corresponding manner to each other; a display processing unit that displays a function list screen on which initial value buttons for calling up an initial value function screen accepting an input of an instruction from the user to execute the function using the initial values, and first registered value buttons for calling up a registered value function screen accepting an input of the instruction from the user to execute the function using the registered values are arranged; and an accepting unit accepting a selection of the initial value button or the first registered value button on the function list screen from the user.

An image forming apparatus includes a generating unit, a print instruction providing unit, and a display. The generating unit generates print data of a sample sheet if a request for outputting the sample sheet is received while print data formed of plural pages is being generated. The print instruction providing unit provides a print instruction for the print data of the sample sheet after providing a print instruction for the print data that has been generated. The display displays, based on the print data of the sample sheet, an attribute of the sample sheet.

An image forming apparatus includes an image forming station for forming an unfixed toner image on a sheet; a fixing portion detachably mountable to the apparatus, said fixing portion including a rotatable member for being contacted by an image carrying surface of the sheet; a jam detector for detecting jamming in said fixing portion; an executing portion for executing a cleaning process for said rotatable member after clearance of the jamming; a storing portion, provided on said fixing portion, for storing information as to whether or not the cleaning process is executed; and a display for displaying a state of capability of image forming operation. The executing portion executes the cleaning process before said display displays the state, when the information stored in said storing portion of said fixing portion mounted in said main assembly indicates non-execution of said cleaning process.

A display control apparatus includes; a display unit; a web display control unit which causes a web page to be displayed; an instruction acceptance image display control unit which causes a download instruction acceptance image to be displayed in a web page; a download instruction acceptance unit which accepts a download instruction in accordance with an operation based on the download instruction acceptance image; a processing acceptance image display control unit which displays a processing acceptance image for accepting an instruction for carrying out printing, saving or transmission in respect of the data to be downloaded, when the download instruction is accepted; and a processing acceptance unit which accepts the selection of any one of the aforementioned processes in accordance with an user's operation based on the processing acceptance image.

When trial printing is executed in a repeat printing mode, trial printing is performed in size of an image of one piece in a layout in which a plurality of images are supposed to be printed in the repeat printing mode normally. A user who has checked a finished state of the trial printing sets, when the finished state is in a desired state, the recording paper on which the trial printing is performed to the paper feed portion again and executes the repeat printing. Thereby, in a blank space excluding a print image which is printed with a first time trial printing, a scheduled quantity of a plurality of images are repeatedly printed.

A control method for controlling a printing apparatus includes printing an image on a sheet; receiving the printed sheet subjected to post-processing; controlling, in a case where the printed sheet subjected to post-processing is to be received in a first orientation, to perform post-processing to the received printed sheet without reversing the printed sheet, and, controlling, in a case where the printed sheet subjected to post-processing is to be received in a second orientation, to perform post-processing to the received printed sheet after reversing the printed sheet; and displaying, in a case where the printed sheet subjected to post-processing is to be received in the second orientation and a type of the sheet subjected to image printing and post-processing is of a type unsuitable for reversal, a screen for changing the type of the sheet to be used for printing and post-processing.

If a sheet is jammed while conveyed, whether the jammed sheet and a sheet preceding the jammed sheet have been generated by cutting an uncut sheet from which the jammed sheet is derived is determined. If generated, a printing apparatus re-prints a plurality of images including an image of the jammed sheet on a sheet, and the cutting apparatus cuts the re-printed sheet. If the jammed sheet and the preceding sheet have been generated, the printing apparatus re-prints a plurality of images including an image of the jammed sheet on a sheet, the cutting apparatus cuts the re-printed sheet, and a sheet that includes the same image as the preceding sheet is discharged to a different discharge destination from that of the preceding sheet.

An image forming apparatus includes a fuser, a detection sensor, a user interface, a memory, and a controller. The fuser is configured to fix an image formed in toner on a sheet thereon. The fuser is attached to a body of the image forming apparatus and is replaceable. The controller is configured to update usage data stored in the memory according to usage of the fuser. After the detection sensor detects the fuser not being attached to the body of the image forming apparatus, in response to the detection sensor detecting the fuser being attached to the body, the controller is configured to control the user interface to display a query screen concerning replacement of the fuser. In response to a replying operation to the query screen by a user, the controller is configured to update the usage data with content concerning a replacing new fuser.

An information processing apparatus which communicates with an image forming apparatus that forms an image on a sheet, the information processing apparatus includes: an acquisition unit configured to acquire error information about an error that has occurred in the image forming apparatus, and maintenance information about maintenance work performed on the image forming apparatus; a memory configured to store a plurality of pieces of error information acquired by the acquisition unit; and a controller. The controller is configured to: determine, from the plurality of pieces of error information stored in the memory, based on the maintenance information, first error information about an error that has occurred during the maintenance work; and determine an error part of the image forming apparatus based on second error information obtained by excluding the first error information from the plurality of pieces of error information stored in the memory.
