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.

It aims to solve a problem that in a printer including a mixture of sheet feeding devices for which points of view regarding the presence/absence of sheets are different, such as a deck-type sheet feeder and a manual feed tray, appropriate warning displays cannot be presented regarding the presence/absence of printing sheets in the respective sheet feeding devices, and thereby improve the operability of a printing system. In a printing system including an image forming apparatus and a print controller, the image forming apparatus has a deck-type first sheet feeder, a tray-type second sheet feeder, and a sheet quantity notification unit for the sheet feeders, and the print controller has a display unit. The print controller displays a warning when there are no remaining printing sheets in the first sheet feeder, and does not display a warning when there are no remaining printing sheets in the second sheet feeder.

An image forming apparatus includes a sheet storage unit including a sheet tray on which one or more sheets are to be stacked, a sensor configured to detect that the sheet storage unit is being operated, and a processor configured to execute a predetermined process after the sensor detects that the sheet storage unit has been operated, and a predetermined condition relating to an occurrence of the sheet conveyance error is satisfied.

There are included: a plurality of feeding units configured to correspond to respective types of sheets; a detecting unit configured to detect whether or not a sheet is mounted in each of the feeding units; and a display control unit configured to display on a display part a preparation screen for printing on a type of sheet corresponding to one of the feeding units in a case where the type of sheet is mounted in the one of the feeding units whereas no sheet is mounted in any of other feeding units at the time a function including a printing function is selected.

A medium transport device includes a drive source, a transport path through which a medium is transported in a transport direction between a first path surface and a second path surface located away from the first path surface, a plurality of projecting portions that projects from the first path surface and is arranged in a width direction intersecting the transport direction, and a moving portion that changes a projecting amount of the projecting portions with respect to the first path surface by power of the drive source between the first path surface and the second path surface.

It is one object of the present invention to provide a thermal history estimation apparatus, a thermal history estimation method and a thermal history estimation program that can estimate variation in thermal history within a plane of a sheet heated by a heating apparatus. The thermal history estimation apparatus includes a first acquisition unit that acquires color information on a sheet plane heated by the heating apparatus, and a first estimation unit that estimates information on variation in thermal history on the sheet plane based on the acquired color information.

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 is an in-body sheet discharge type image forming apparatus including an image forming portion and an image reading portion that is arranged above the image forming portion. The image forming apparatus comprises a sheet discharge tray and an operating panel. The sheet discharge tray is provided in an in-body sheet discharge portion between the image forming portion and the image reading station. On the sheet discharge tray, a sheet having been formed with an image by the image forming unit is discharged. The operating panel is provided on a front side of the sheet discharge tray. A part of a rear side of the operating panel overlaps with a sheet placement area having a front edge that is set on a front side compared to a rear end portion of the sheet discharge tray.

An image recording device includes: a conveyer configured to convey a sheet set in a first feeding tray in a state in which the sheet is wound in a roll shape to serve as a roll sheet; a recording device configured to record an image on the sheet conveyed by the conveyer; a display; and a controller. The controller is configured to execute: a process of stopping conveyance of the sheet in response to detection of an abnormality in the sheet after the conveyance of the sheet is started; and a process of causing the display to display thereon at least one object display screen which indicates, by an object, a target location to restore the abnormality in the sheet to a normal state.

In order to display information for rejected paper sheets in an easily recognizable manner, the paper sheet handling apparatus includes: a transport path configured to transport paper sheets; a recognition unit configured to recognize the paper sheets transported in the transport path; a reject unit configured to stack rejected paper sheets discharged from the transport path based on a recognition result by the recognition unit; and a display unit configured to display information for rejected paper sheets in a manner which is different for a case where the number of the rejected paper sheets stacked in the reject unit can be determined, and for a case where the number of the rejected paper sheets stacked in the reject unit cannot be determined.
