An image forming apparatus includes a printing device, a rotator, an upstream support stand. The printing device prints an image on a plate-shaped printing medium. The rotator rotates while nipping the plate-shaped printing medium and conveys the plate-shaped printing medium to the printing device. The upstream support stand supports the plate-shaped printing medium at a position upstream from the rotator in a conveyance direction of the plate-shaped printing medium and includes a mount. The mount is detachably attached to the rotator.

Examples described herein include a star wheel mount that includes a support element. The support element includes a first clip element coupled to a first end to engage a first mounting element on a media handler housing, and a second clip element coupled to a second end opposite the first end to engage a second mounting element on the media handler housing. The star wheel mount also includes a star wheel support axle coupled to hold a star wheel in a plane perpendicular to a surface of the media handler housing.

In accordance with an embodiment, a sheet processing apparatus comprises a first tray, a second tray, a third tray, a lower supporting plate, a drive section and a control device. The second tray is located at the lower part of the first tray. The third tray is located at a downstream side with respect to the second tray in a sheet conveyance direction. The lower supporting plate can support the sheet from the lower part. The drive section drives the lower supporting plate. The control device controls the drive section to arrange the lower supporting plate at the downstream side with respect to a conveyance starting point of the sheet in the sheet conveyance direction in a case of skipping the first tray and the second tray to convey the sheet to the third tray.

Provided is a printing apparatus that prevents a print medium from buckling during discharging, a method of controlling a printing apparatus, and a storage medium. In the case where the print conveyance speed determined by the print mode is higher than or equal to the specified speed, the print medium after printing is conveyed to the discharging tray at the print conveyance speed, and in the case where the print conveyance speed determined by the print mode lower than the specified speed, the print medium after printing is conveyed to the discharging tray at the specified speed increased from the print conveyance speed.

An insertion assembly for the continuous and automated feeding of laminar elements into a graphic printing station without the involvement of roller elements in the process, allowing the distance between the laminar elements in question to be adjusted such that adjacent laminar elements may be positioned very close to each other regardless of their length. Said assembly comprises an insertion device (1) that includes a rotating belt system on which the laminar elements (3) can be moved horizontally, and suction means, with the insertion device (1) connected to a stacking area (4) and; a pulling device (2) that includes a rotating belt system on which the laminar elements from the insertion device (1) can be moved, and suction means, with the pulling device (2) connected to a graphic printing station, said pulling device adjoining the insertion device (1) in a direction of forward motion.

An example print medium loading device includes a loading unit on which a print medium is loadable, a transporting roller unit to transport a print medium toward the loading unit, and a moving gate between the loading unit and the transporting roller unit. The loading gate moves according to locations to which the print medium is transported. In an example, when a first print medium is loaded on the loading unit and the transporting roller unit transports a second print medium toward the loading unit, the moving gate is positioned at the first location to overlap a trailing end of the first print medium toward the moving gate. When the leading end of the second print medium is past the moving gate and the second print medium is loaded on the loading unit, the moving gate sequentially moves through the first through fourth positions.

A sheet discharging device includes a housing, a drive roller, a first pinch roller, a second pinch roller, a holder, a guide member, and an urging member urging the first pinch roller toward the drive roller. The second pinch roller is positioned downstream of the first pinch roller in a discharging direction. The holder has a connecting portion supporting the first and second pinch rollers. The first pinch roller is movable between a contact position in contact with the drive roller and a separated position separated from the drive roller. Between the first and second pinch rollers in the discharging direction, the guide member is farther away from the drive roller than the connecting portion is when the first pinch roller is at the contact position, and is closer to the drive roller than the connecting portion is when the first pinch roller is at the separated position.

An assembly (100) and method for bottoming feeding sheets from a stack of sheets to a top-feed sheet feeding mechanism (F) on a device (P), such as a copy machine. The assembly (100) includes a sheet feeder (200), a transport arm (300), and a final height adjustment block (420) translatably attached to and extending along the distal end (302) of the transport arm (300) for limited transverse (T) translation relative to the machine direction (MD).

A sheet discharging apparatus configured to discharge a sheet includes a discharging portion, a contact member, and a detector. The discharging portion discharges a sheet so as to be bent in a curved shape in a width direction of the sheet, perpendicular to a discharging direction of the sheet when viewed in a sheet discharging direction. The contact member is moved by contact with the sheet discharged by the discharging portion, wherein the contact member includes a contact surface to be in contact with the sheet which is inclined along the curved shape of the sheet in the width direction of the sheet when viewed in the sheet discharging direction. The detector detects a discharging of the sheet based on the movement of the contact member.

An image forming apparatus includes: an image former; a main conveyance path that conveys the sheet to a downstream side; a reverse conveyance path that reverses the sheet; a two-side conveyance path that branches at a first branch point and sends the sheet back into the image former; a reverse ejection conveyance path that branches at a second branch point and sends the sheet to a downstream side of the main conveyance path; a two-side roller that is rotating to reverse a direction of conveyance of the sheet and send the sheet into the two-side conveyance path; and a reversing roller that is rotating to reverse the direction of conveyance of the sheet and send the sheet into the reverse ejection conveyance path, wherein the reversing roller is disposed on a downstream side of the two-side roller, as viewed from an ejection side of the image former.
