An image forming system includes an image forming unit, a pressure-bonding processing unit, a display portion, and a control unit capable of controlling the image forming unit by acquiring image data for forming a toner image on a recording medium in an operation in an image forming mode. The control portion controls the display portion to issue a warning in a case that the toner image to be formed on an inner surface of the recording medium to be folded protrudes outside a film region, the film region being a region of the inner surface to which a thermosensitive adhesive film is to be supplied.

An image forming system includes: a sheet feeder; an image former that forms an image on a paper sheet; a conveyor that conveys a paper sheet to a sheet ejection destination; a switcher that switches sheet ejection destinations; a reader that optically reads a paper sheet, and outputs a read image; an abnormal sheet detector that detects an abnormal paper sheet by analyzing the read image; a storage; a display; and a hardware processor that performs: ejection destination switch control to control the switcher to eject an abnormal paper sheet and a succeeding paper sheet to a second ejection destination different from a regular ejection destination; storage control, for each of the abnormal paper sheet and the succeeding paper sheet, to associate sheet information, the read image, and a stacking order with one another, and store them into the storage; and display control to cause the display to display them.

An image forming apparatus includes: a feed tray that contains printing paper therein; a user authentication unit that authenticates a user who is permitted to print; a paper loading detection unit that detects printing paper loaded into the feed tray; a memory device that stores a user authenticated as a paper-supplementing user; a paper feeding mechanism that feeds the printing paper from the feed tray; a paper jam detection unit that detects a paper jam; and a controller that controls a print job. The controller, when a paper jam has occurred, determines whether or not the paper jam is due to the paper-supplementing user having loaded the printing paper in an improper manner. Upon determining that the paper jam is due to the paper-supplementing user having loaded the printing paper in an improper manner, the controller, subsequently when the paper-supplementing user uses, requests that a loading condition be checked.

A post-processing device includes: multiple types of post-processing modules that are disposed at predetermined installation positions within the post-processing device and each execute post-processing to an output sheet on which an image is formed; and a controller that (i) detects the post-processing modules at the installation positions and (ii) determines and controls adjustment contents of the post-processing modules based on a detection result.

An image forming apparatus includes an image forming portion, a belt, a plurality of stretching rollers including an inner roller and an upstream roller, an outer member, an urging member, a first position changing mechanism, a storing portion, a controller, and an operating portion. The controller controls the first position changing mechanism on the basis of a kind of a recording material on which an image is formed, first set information stored in the storing portion, and first input information for changing setting of a position of the urging member inputted to the controller through the operating portion.

A control device includes a processor and a memory coupled to or integrated with the processor and controls an information processing apparatus, in which the processor is configured to simultaneously display, in an operation screen, a selection list of tasks for selecting a task to be executed by the information processing apparatus and a slide button as an execution button for instructing execution of the selected task, and once an operation of instructing execution of the task by the slide button is detected, performs control to change the slide button to a cancel button for canceling the task that is being executed.

An image forming apparatus includes an image forming section, a display section, and a controller. The image forming section forms an image on a recording medium. The display section displays a message to a user. The controller controls operation of the display section. In causing the display section to display a remaining amount display icon indicating a remaining amount display bar with a length that represents a remaining amount of a consumable used in the image forming section, the controller causes the display section to display in an enlarged size the remaining amount display icon indicating the remaining amount display bar with a length corresponding to a maximum remaining amount and continuously changes the length of the remaining amount display bar from the length corresponding to the maximum remaining amount to a length corresponding to a current remaining amount.

A system displays a plurality of display objects respectively corresponding to a plurality of symptoms of an image forming apparatus, receives a selection of one display object from among the plurality of display objects, and displays a screen for receiving, from a user, a value related to a predetermined item to be adjusted to improve a symptom corresponding to the selected display object.

According to one embodiment, there is provided an image forming device, the image forming device applying information differently for each copy to a sheet on which an image is to be formed. The image forming device includes a controller and an image forming processor. The controller is configured to acquire image information, the image information including an input image to be formed on a sheet and applying information associated with each copy, in response to the input image being formed. The controller is configured to generate a composite image obtained by applying an applying image based on the applying information for each copy to the input image. The image forming processor is configured to form the composite image generated for each copy on the sheet of each copy.

To provide an image forming device that can be efficiently maintained. According to one embodiment, the image forming device includes a plurality of photoconductors, an exposure device, a developer, and a processor. The exposure device irradiates a corresponding surface of the plurality of photoconductors with light corresponding to an image formed on a corresponding photoconductor of the plurality of photoconductors. The developer supplies a toner to the corresponding surface of the plurality of photoconductors on which an electrostatic latent image is formed by the light emitted by the exposure device. The processor adjusts, for every photoconductor, a contrast potential for supplying the toner from the developer to the electrostatic latent image formed on the corresponding surface of the plurality of photoconductors, and notifies a warning when there is a contrast potential whose difference from another contrast potential exceeds a reference value.
