A sheet discharging apparatus includes a discharge unit, a stacking portion and a swing guide. The stacking portion includes an upstream supporting portion, a wall surface portion, a first supporting portion provided downstream of the upstream supporting portion and including a first inclined surface, and a second supporting portion provided downstream of the upstream supporting portion and including a second inclined surface. The swing guide overlaps with the first supporting portion as viewed in a width direction of a sheet in a case where the swing guide is not in contact with a sheet discharged by the discharge unit, and swings upward in a case where the swing guide is pushed by a sheet.

A printing apparatus has a sheet holding unit having a detection unit for detecting a size of a sheet which is held and a storage unit configured to store sheet information including at least a size of a sheet as information representing a sheet. The apparatus sets first sheet information selected by a user in association with the sheet holding unit from a plurality of items of sheet information stored in the storage unit and notifies the user of a mismatch in a case where a size of a sheet that the first sheet information set in the setting indicates, and a size of a sheet detected by the detection unit are mismatched.

A printer that allows selection of a plurality of types of print media includes, a control unit that stores a plurality of pieces of registration information, the registration information including one set of a plurality of printing setting items used for printing, the plurality of printing setting items include an item regarding the type of the print medium.

An image forming device comprises a media container accommodating a sheet-type medium, an image forming engine, a media conveyor configured to convey the sheet-type medium along a conveyance path from the media container to the image forming engine. The media conveyor has a plurality of conveying rollers including a first conveying roller arranged on an upstream side of the image forming engine and a second conveying roller arranged on a downstream side of the image forming engine. The image forming device further comprises a cutter arranged on an upstream side along the conveyance path with respect to the second conveying roller, and a controller. The controller is configured to control the media conveyor in such a manner that the cut sheet-type medium is conveyed and discharged toward outside after a power is on and before first execution of the image forming process.

A printing system for printing on tabbed media having a plurality of tab positions. A media transport system picks the next sheet of tabbed media from a media tray. A detection system detects the tab position for the sheet of tabbed media. The detected tab position is compared to an expected tab position and if the detected tab position is different from the expected tab position then either the front end is used to supply image data to be printed on the sheet of tabbed media having the detected tab position, or the media transport system is controlled to direct the sheet of tabbed media into a waste receptacle and pick one or more additional sheets of tabbed media until the detected tab position is the same as the expected tab position.

A printing system for printing on sheets of media having asymmetric media characteristics. A media transport system is controlled to pick a next sheet of media from a media tray. A detection system detects a media orientation of the sheet of media. A front end supplies image data having an orientation matching the detected media orientation, and a printing module prints the supplied image data on the sheet of media in accordance with the detected media orientation.

A sheet conveying device includes a sheet placement table, a sheet discharge table, a conveyance mechanism, raising/lowering mechanism, and a raising/lowering control portion. The sheet discharge table is located below the sheet placement table. The conveyance mechanism conveys a sheet placed on the sheet placement table onto the sheet discharge table via an execution position at which image processing is executed by an image processing portion. The raising/lowering mechanism raises and lowers the sheet placement table. The raising/lowering control portion controls the raising/lowering mechanism to lower the sheet placement table when a human detection sensor configured to detect a human in a detection region has detected a human in the detection region.

A sheet conveying device includes a sheet placement table, a sheet discharge table, a conveyance mechanism, raising/lowering mechanism, and a raising/lowering control portion. The sheet discharge table is located below the sheet placement table. The conveyance mechanism conveys a sheet placed on the sheet placement table onto the sheet discharge table via an execution position at which image processing is executed by an image processing portion. The raising/lowering mechanism raises and lowers the sheet placement table. The raising/lowering control portion controls the raising/lowering mechanism to raise and lower the sheet placement table to a target position that is determined in accordance with a size of the sheet on the sheet discharge table.

An image forming apparatus includes a platen on which an original is to be placed, a feeder configured to feed an original placed on a tray, a sensor configured to detect a sheet on the tray, a lamp provided to the feeder, a reader configured to read the original placed on the platen and to read the original conveyed by the feeder, an image forming unit configured to form an image on a sheet, and a controller. The controller is configured to control the image forming unit to form a first test image on a sheet, control the reader to read the first test image formed on the sheet placed on the platen, control a density of the image to be formed by the image forming unit based on a reading result of the first test image.

A printer that allows selection of a plurality of types of print media includes, a control unit that stores a plurality of pieces of registration information, the registration information including one set of a plurality of printing setting items used for printing, the plurality of printing setting items include an item regarding the type of the print medium.
