An image forming apparatus includes a first execution circuit, a second execution circuit, and a display circuit. The first execution circuit is configured to execute a first calibration. The second execution circuit is configured to execute a second calibration. The first display circuit is configured to, in a first notification related to a setting of a calibration, display a first object for prompting the execution of the first calibration and not display a second object for prompting the execution of the second calibration, in a first notification related to a calibration setting.

An image processing apparatus that prevents erroneous use of paper by enabling registration of user identification of a user who can use a paper feed deck in information about each paper feed deck of the image processing apparatus and controlling paper feeding so that just the user associated with the user identification can use a paper feed deck to which the user identification was added.

An image forming apparatus includes a sheet supporting portion, a regulating portion, a feeding portion, an image forming unit, a sheet detection unit, and a control unit. The control unit is configured to execute, in a state where an image forming job in which an image is formed by the image forming unit is interrupted, a drive processing of the feeding portion such that (a) the feeding portion is driven at a first timing if the regulating portion is not set to a moved state within a predetermined period of time from when the sheet detection unit has detected the sheet, and (b) the feed portion is driven at a second timing later than the first timing if the regulating portion is set to the moved state within the predetermined period of time from when the sheet detection unit has detected the sheet.

An image forming apparatus to which a first feeding device which does not notify abnormal sheet feeding or a second feeding device which notifies the abnormal sheet feeding is connectable includes a sheet receiving portion, a sheet detector, an image forming unit, and a controller. In a case that the first feeding device is connected to the image forming apparatus, the controller discriminates that the abnormal sheet feeding occurs in the first feeding device when the detector does not detect the sheet at first timing. In a case that the second feeding device is connected to the image forming apparatus, the controller discriminates that the abnormal sheet feeding occurs at the sheet receiving portion when the detector does not detect the sheet at second timing and notification of the abnormal sheet feeding is not provided from the second feeding device.

A system for detecting the level of a media supply in a printer has a frame having a support for seating the printer thereon. A first light source is positioned on the support and is energizable to direct a first beam of light into the printer. A first detector is positioned on the support and provides an analog signal in response to reflection of the first beam of light from within the printer. A control logic processor is in signal communication with the first detector and compares the analog signal to a stored/predetermined value and reports a low media condition according to the comparison.

An image forming apparatus includes: an image former, a paper feed tray that feeds a sheet to the image former, a display that displays a list of tray information on the paper feed tray, based on a mounting order with respect to an apparatus; and a controller that controls display of the display. The controller changes a display order of a list of the tray information according to a display priority based on an image forming operation.

An image forming system includes an image forming apparatus, a pressure-bonding processing apparatus, an inputting portion, and a display portion. The displaying portion displays a pressure-bonding printed matter prepared by changing directions of a front surface and a back surface of the recording material in a case that the directions of the front surface and the back surface of the recording material inputted by the inputting portion are different from directions of the front surface and the back surface of the recording material when the pressure-bonding printed matter is capable of being properly prepared.

The image forming device includes a recording paper setting plate on which media are set, a paper end sensor lever, and a print control section that controls the whole of the device. The paper end sensor lever includes a paper contact part for detecting a first condition in which there are no media set on the recording paper setting plate and an arm contact part for detecting a second condition in which the amount of the media set on the recording paper setting plate is smaller than a prescribed amount.
