There are a paper storage that stores paper on which an image is formed, a paper guide that is movably provided in the paper storage and restricts a position of the stored paper, a paper size acquirer that acquires a size of the paper stored in the paper storage, a size change determiner that determines, by using the acquired size of the paper, whether the paper stored in the paper storage was changed, a confirmation information selector that, when it is determined that the paper stored in the paper storage was changed, selects confirmation information requesting confirmation of a position of the paper guide in the paper storage in accordance with a difference in size between paper before and after the change, and a confirmation information notifier that notifies the selected confirmation information.

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 sheet processing device separates a two-ply sheet in which two sheets are overlapped and partially bonded and sandwich a sheet medium between the two sheets. The sheet processing device includes a relay conveyance path, a sheet loader, and control circuitry. The sheet medium is fed from an image forming apparatus connected upstream of the sheet processing device through the relay conveyance path. The sheet loader loads at least one of the two-ply sheet and the sheet medium. The control circuitry performs a mixing mode to feed the two-ply sheet or the sheet medium from the sheet loader.

An image recording apparatus including a first tray having a first holding portion for holding sheets, a second tray disposed above the first tray and including a second holding portion for holding sheets, a sheet feeder that selectively feeds a sheet from one of the first tray and the second tray in a sheet feed direction, a recording unit that records an image on the sheet fed by the sheet feeder, and a discharge roller that discharges the sheet on which the image is recorded by the recording unit. The second holding portion of the second tray moves above the first holding portion of the first tray. The second tray further includes a discharged sheet receiving portion for receiving the sheet discharged by the discharge roller. The second tray including the discharged sheet receiving portion pivots relative to the first tray.

A removable media tray with an adjustable rear tray extension operable by a rear media restraint. The tray extension is slidably attached to a front section of the tray via a cam having a locking arm engaged in a J-slot. When in the curved portion of the J-slot the front section and tray extension are locked together. A rear media restraint slidably latching to a track in the bottom of the tray has a locking lobe that engages with a locking notch on the cam. As the media restraint is slid toward the rear, the locking lobe initially rotates the cam moving the locking arm to the straight section of the J-slot, then the locking lobe engages with the locking notch, locking the media restraint to the tray extension. Thereafter, the media restraint and tray extension move together until the end of the J-slot is reached by the locking arm.

A sheet feeding cassette includes a main body, a lift plate, a pair of side cursors, and an auxiliary lift plate. The main body is configured to accommodate a sheet fed out in a predetermined sheet feeding direction. The lift plate is provided in the main body in a liftable manner, and has a sheet placement surface on which the sheet is placed. The pair of side cursors is configured to be moved in a width direction perpendicular to the sheet feeding direction and to come into contact with side edges of the sheet placed on the lift plate to align the sheet. The auxiliary lift plate is detachably attached to a notch portion which is formed in the lift plate so as to allow a moving of the side cursors.

The sheet processing device includes a relay conveyance path, a sheet loader, and control circuitry. The sheet medium is fed from an image forming apparatus connected upstream of the sheet processing device through the relay conveyance path. The sheet loader loads at least one of the two-ply sheet and the sheet medium. The control circuitry performs a mixing mode to feed the two-ply sheet or the sheet medium from the sheet loader.

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.

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.

A printer having front-end paper feeding and front-end paper outputting and being capable of changing a paper discharge path, said printer comprising a housing (10) and a paper discharge unit (40), the paper discharge unit (40) comprising a first paper discharge mechanism (401) and a paper discharge channel (50) which consists of upper and lower casings (1011, 1012), a front end surface of the housing (10) being a vertical flat surface A, a paper feed port (30) and a paper output port (20) being horizontally arranged on the flat surface A, the paper feed port (30) being located beneath the paper output port (20), the paper discharge channel (50) at the front of the first paper discharge mechanism (401) being provided with a paper conveyance system capable of changing a paper discharge path.
