A control unit includes a touch panel display capable of presenting preview display of multiple pages of document images in a scrollable manner on the display panel. The touch panel display controller includes: a commanded position detecting controller that detects a commanded position relative to one of document images being a reference in the preview image displayed on a display panel; a preview layout direction switching controller that switches the layout direction in the preview image in accordance with the commanded position; and a scroll direction switching controller that switches the scrolling direction in the preview image in accordance with the detected commanded position.

A display apparatus has a camera portion which shoots an operation panel, a display portion which displays information while allowing a user to see the operation panel, and a control portion which recognizes the position of the operation panel in the display area of the display portion and the currently displayed screen currently being displayed by the operation panel and which makes the display portion display, in such a way as not to overlap the operation panel, item information indicating the item description of an item button arranged on a screen to which a shift is possible from the currently displayed screen.

An image processing apparatus displays, based on detection of a maintenance event, a first maintenance screen including a moving image illustrating a maintenance method corresponding to the maintenance event, and displays a second maintenance screen including the moving image illustrating the maintenance method based on receipt of a display instruction to display the maintenance method in a state where the maintenance event is not detected.

An image forming apparatus is provided and controls a display device to cause a display of an object associated with specific user information in a user selection screen to notify information relating to the number of pieces of specific print data associated with the specific user information.

An image forming apparatus is provided which can properly manage individual information after replacement and history of replacement on the apparatus side. If individual information is successfully read from a toner cartridge storing the individual information, the image forming apparatus records the individual information in an apparatus-side memory. At a predetermined timing of when there is a possibility that the toner cartridge is replaced, the image forming apparatus attempts to read information from the toner cartridge. If the reading fails and the individual information recorded in the apparatus-side storage is not information read from the toner cartridge, the image forming apparatus writes new individual information about the toner cartridge to the apparatus-side storage, and records information generated on the apparatus side in the written individual information.

An image forming apparatus includes: a display part that displays information related to image formation; a detection part that detects an abnormal paper feeding when a paper sheet is fed from a paper feed tray storing a paper sheet; and a hardware processor that causes the display part to display a paper feed adjustment screen to which a user can input an adjustment of a paper feed condition at a time of paper feeding, when the detection part detects an abnormal paper feeding.

A processing apparatus includes: a processing unit that performs a process related to image data; a display unit that displays a process selection portion, with which the process performed by the processing unit is associated and which is selected to start the process by the processing unit; and a creation unit that, in a case of creating the process selection portion to be displayed in the display unit, creates the process selection portion while associating data with the process selection portion.

An image forming apparatus includes a display, a display controller, a cover, a cover sensor, a recording sheet sensor, and a jam solution work progress managing unit. The display controller causes the display to continuously display a guidance video in a process sequence when the recording sheet jam occurs. The guidance video shows a work procedure constituted of a plurality of processes for a solution work for a recording sheet jam. The jam solution work progress managing unit manages a progress of the solution work for the recording sheet jam. When the jam solution work progress managing unit determines that the solution work for the recording sheet jam is not performed while the cover sensor detects closing of the cover, the display controller causes the display to repeatedly display a guidance video showing a work procedure for a first process in the solution work for the recording sheet jam.

An image forming apparatus has a power supply circuit including a power circuit, a main circuit, and a sub-circuit. The sub-circuit includes a timer that performs electrical conduction of a driving contact point of a heater by a first setting time and performs electrical conduction of a driving contact point of a discharge fan by a second setting time when a power switch is turned off. When it is determined that humidity in an image forming apparatus body detected by a humidity detection sensor is equal to or more than a threshold value, the first setting time is set to 0 and the second setting time is set to a predetermined time larger than 0. When it is determined that the humidity is less than the threshold value, the first setting time is set to a predetermined time larger than 0 and the second setting time is set to 0.

An information processing apparatus is communicably connected to an image forming apparatus and acquires a consumption amount of a consumable in the image forming apparatus, outputs a delivery request for a replacement consumable based on the acquired consumption amount, and notifies information for prompting to stock a spare replacement consumable based on the consumption amount.
