A medium-transport apparatus includes: an apparatus main body having the transport path for transporting the medium; and a cover CV provided on the side surface of the apparatus main body and configured to be switched between a first state of exposing the transport path and a second state of covering the transport path. The cover CV is divided into: a first cover that has the rotation shaft along a Z-axis and is rotatable with respect to the apparatus main body; and a second cover that is arranged on a −Z side of the first cover, has the rotation shaft along a Y-axis on the Z− side, and is rotatable with respect to the apparatus main body.

A card separation apparatus includes a movable tray having a surface onto which a sheet is conveyed after a card has been separated from the sheet, and a card separation unit mounted on the surface for movement with the movable tray, the card separation unit having an opening through which the sheet is conveyed, and a controller configured to send an instruction to the movable tray to be moved at a predetermined timing after a leading edge of the sheet to which the card is attached enters the opening, so as to cause the sheet to be initially separated from the card.

A supply device includes: a loading portion where recording media are loaded; a transport unit to transport the media; a contact portion provided on the loading portion, the contact portion being in contact with a side end portion of the media having a first size in a direction intersecting with a transport direction, the contact portion having a blowing portion to blow air to the side end portion; a guide portion detachably attached to the contact portion when media having a second size smaller than the media having the first size are loaded, the guide portion being configured to guide a side end portion of the media having the second size; and a duct provided in the guide portion, the duct including a discharge port to blow the air from the blowing portion to an upper end portion of the media having the second size loaded on the loading portion.

A medium-transporting device includes: a medium-support section that has a first mounting surface inclined relative to a horizontal plane; a transport path for transporting a medium; a discharge stacker that is configured to switch between an extended state in which a second mounting surface that is inclined relative to the horizontal plane and that receives the medium discharged along the transport path is formed and a stored state in which the second mounting surface is stored in the medium-transporting device, a control section is configured to perform first control of switching the discharge stacker from the extended state to the stored state after the medium is discharged to the second mounting surface and second control of not switching the discharge stacker from the extended state to the stored state such that the medium remains mounted on the second mounting surface.

Printer tray orientation and print size selection includes receiving printable media in a tray of a printer. Tray guide positions of the tray are measured. An overall list overall list of all sizes of printable media capable of fitting in the tray is created by comparing dimension ranges of the tray guide positions to a predetermined media size dimension list for the tray in multiple orientations. A prioritized list of printable media sizes capable of fitting in the tray for given tray guide positions is created. A preferred printable media size is selected based on the prioritized list.

An image forming apparatus includes a storing unit that stores information associated with a sheet type of a sheet and a sheet feed source, of a plurality of sheet feed sources, a selection unit that selects a sheet feed source from the plurality of sheet feeding sources based on at least a sheet type designated by a job and the stored information, and a feeding unit that feeds a sheet from the selected sheet feed source. The image forming apparatus also includes an image forming unit that forms an image on the sheet fed by the feeding unit, and a detector that detects a sheet type of the sheet fed from one of the plurality of sheet feed sources by the feeding unit. The storing unit stores the sheet type detected by the detector as the information indicating the sheet type of sheet stored in the sheet feeding source.

A medium feeding apparatus includes a medium mounting section, a movable edge guide that guides both edges of the medium mounted on the medium mounting section and has a first edge guide and a second edge guide, a feeding section, and a width adjuster configured to adjust a guide width depending on the medium. The width adjuster includes a first adjuster having a first holding section and a first guiding section, and the second adjuster having a second holding section and a second guiding section. The first holding section holds a part of the first edge guide, the first guiding section guides the edge of the medium between the first edge guide and the second guiding section, the second holding section holds a part of the second edge guide, and the second guiding section guides the edge of the medium between the second edge guide and the first guiding section.
