An image processing apparatus includes a display device and a processor. The processor is configured to generate a first screen for display on the display device and on which one of a plurality of malfunctioning part candidates of the image processing apparatus and one of a plurality of timings at which a particular sound was output by the image processing apparatus that malfunctioned, are selectable, when a first malfunctioning part candidate and a first timing are selected on the first screen, generate a second screen for display on the display device and on which one or more reference sounds corresponding to the particular sound are selectable, and when one of the reference sounds is selected on the second screen, generate error information indicating the first malfunctioning part candidate and the selected reference sound.

A printing system that enables a user to determine the number of sheets that a printing apparatus can print, the number of sheets corresponding to a power supply source that supplies power to the printing apparatus, in any power mode. The printing apparatus performs printing in any of a plurality of power modes including (i) a first power mode in which the printing apparatus is supplied with power from the battery, and (ii) a second power mode in which the printing apparatus is supplied with power supplied from both the battery and an external power supply. In the second power mode, the number of sheets that the printing apparatus can print is calculated based on the remaining battery level of the battery and an amount of power supplied from the external power supply.

An image processing apparatus includes: a display; a memory that stores multiple key frames of a video guide on how to recover from an operating error; an error sensor that detects the operating error; and a display processor that allows the display to display at least one of the multiple key frames as a still frame for a digest along with an operation button for video playback, when the error sensor detects the operating error, the multiple key frames being stored on the memory, and that further allows the display to play back the video guide by serially displaying the multiple key frames, when the operation button is pressed.

In an image forming apparatus, an event detection unit detects occurrence of an event which requires replacement of a part, a notification unit notifies guidance for replacing the part if the event detection unit detects occurrence of the event, and a control unit ends a notification of the guidance using, as conditions, a case in which a cover open to perform the replacement is set in a closed state and a case in which an input of an instruction that the replacement has completed is accepted.

An image processing apparatus including a display unit includes a processor and a memory storing instructions, when executed by the processor, causing the image processing apparatus to function as a detection unit that detects occurrence of a sheet jammed inside the image processing apparatus and a display control unit that displays a screen based on detection of the occurrence of the jammed sheet. The screen includes a first region for displaying work that a user carries out to remove jammed sheets from inside the image processing apparatus and a second region for displaying work that the user carries out after removing the jammed sheets from inside the image processing apparatus.

An information processing apparatus includes a memory to store information of a display status of setting item buttons used for selecting corresponding setting items on a screen, and information of at least one of the setting items corresponding to an error that occurs during information processing as an error-occurred setting item, and circuitry to detect occurrence of the error during the information processing, determine whether a setting item button corresponding to the error-occurred setting item is displayed or not on the screen when the occurrence of the error is detected during the information processing, and display the setting item button corresponding to the error-occurred setting item on the screen based on a determination that the setting item button corresponding to the error-occurred setting item is not displayed on the screen when the occurrence of the error is detected during the information processing.

An image processing apparatus includes a processor for acquiring an image of a reference member, calculating a dirt degree at an imaging position by comparing a gradient value of a pixel with a gradient value of peripheral pixels of the pixel or comparing the gradient value of the pixel with a reference value, with regard to a pixel included in the acquired image of the reference member, and generating when the dirt degree is equal to or more than a first threshold. When the dirt degree is less than the first threshold and equal to or more than a second threshold that is smaller than the first threshold, the processor generates the warning only when a scan count exceeds a scan count threshold, and when the dirt degree is less than the second threshold, the processor does not generate the warning.

An image forming apparatus includes: a display portion; an error sensor that detects an operating error; a recovery sensor that detects the recovery from an operating error; and a display processor that makes the display portion display a notice of an operating error when the error sensor detects the operating error and that makes the display portion display an operation guide for preventing the reoccurrence of the same operating error when the recovery sensor detects the recovery from the operating error.

An image forming apparatus includes an image forming unit configured to perform a printing process of forming an image on a print medium based on print data, and a processor. The processor is configured to determine whether or not the printing process has completed based on remaining print data to be printed, when the print medium is removed from a paper discharge tray in which the print medium on which the image is formed by the image forming unit is placed, and to cause a warning to be output upon determining that the printing process has not completed based on the remaining print data to be printed.

An apparatus includes circuitry to receive an input of problem information that is information on a problem, transmit the problem information to an information processing apparatus communicably connected to the apparatus via a network, and receive, from the information processing apparatus, troubleshooting information corresponding to the problem information. The troubleshooting information is information for solving the problem. The circuitry outputs the troubleshooting information, and transmits, to an extraneous resource, a repair request including the problem information and information indicating whether the troubleshooting information has been output.
