Various embodiments of a printer modification system for modifying a printer to accommodate different sized documents such as elections documents are disclosed herein.

An image forming apparatus includes a cover portion and an auxiliary tray. The cover portion is displaced between a closing position for closing the supply port and an opening position for opening the supply port. The auxiliary tray is attached to a sheet stack surface of the cover portion, and supports the sheet, together with the cover portion at the opening position. The auxiliary tray is, either in a first attachment state or in a second attachment state, attached to the cover portion. In the first attachment state, a longitudinal direction of the auxiliary tray extends along a width direction that crosses a sheet insertion direction and the auxiliary tray is stored in the sheet stack surface. In the second attachment state, the longitudinal direction extends along the sheet insertion direction, and the auxiliary tray extends out from the cover portion toward an upstream in the sheet insertion direction.

A post-processing unit is disposed so as to face the apparatus side surface of a printer that has a manual feed tray protruding from the apparatus side surface. The post-processing unit has an ejection tray, which is movably provided in a unit body and to which paper accepted from the printer is ejected. In an apparatus height direction crossing a direction in which paper is ejected, the ejection tray can be moved to a first position at which ejected paper can be mounted and to a second position at which part of paper mounted on the manual feed tray can be supported.

A medium discharge includes a first tray having a first medium receiving surface, a second tray having a second medium receiving surface for receiving the medium discharged from the first tray, a discharge section that discharges the medium disposed on the first tray to the second tray, and a push-down portion that is located downstream of a downstream end of the first medium receiving surface in the medium discharge direction, and that is located at a place deviated from the discharge section in a width direction that is a direction intersecting with the medium discharge direction, and pushes down a part of an upstream end of the medium to be discharged in the medium discharge direction.

Various embodiments of a paper feed and tray extension system for adapting printer components to accommodate election document dimensions are disclosed herein. To accomplish this, a printer feed adapter system includes a paper tray extension for implementation within an existing printer that extends a paper tray to enable the paper tray to receive sheets of paper that have required dimensions for election documents. Further, paper catch extender extends a paper catch to enable the paper catch to catch election document sheets following processing by the printer.

An example paper cassette includes a cassette portion; a sliding portion to slide relative to the cassette portion to adjust a length of the paper cassette, the sliding portion initially being in a shipping position defining a shipping length of the paper cassette and deployable to different deployment positions at which the paper cassette is longer than the shipping length; and a length selection mechanism to: mechanically select one deployment position of the different deployment positions, while the sliding portion is in the shipping position; lock the sliding portion at the one deployment position, relative to the cassette portion when the sliding portion first slides from the shipping position.

A sheet discharge device includes a sheet discharge portion, a sheet loading portion, and a stopper mechanism. The stopper mechanism includes a first stopper supported pivotably to a first retraction position and a first restriction position, a second stopper that is movable to a first position at which the second stopper is housed along a downstream end part of the sheet loading portion and a second position apart from the first position to a downstream side in a sheet discharge direction and is supported pivotably to a second retraction position and a second restriction position, and a link mechanism connecting the first stopper to the second stopper. When the second stopper is disposed at the first position, the first stopper is disposed at the first restriction position, and when the second stopper is disposed at the second position, the first stopper is disposed at the first retraction position.

A sheet discharge device includes a sheet discharge portion, a sheet loading portion, and a stopper mechanism. The stopper mechanism includes a first stopper supported pivotably to a first retraction position and a first restriction position, a second stopper that is movable to a first position at which the second stopper is housed along a downstream end part of the sheet loading portion and a second position apart from the first position to a downstream side in a sheet discharge direction and is supported pivotably to a second retraction position and a second restriction position, and a link mechanism connecting the first stopper to the second stopper. When the second stopper is disposed at the first position, the first stopper is disposed at the first restriction position, and when the second stopper is disposed at the second position, the first stopper is disposed at the first retraction position.

An automatic document feeder includes a media path to route media through the automatic document feeder, at least one media tray to one of supply the media to the media path and receive the media from the media path, and an automated media tray extender at an end of the media tray, the automated media tray extender to be positioned based on a presence of the media in the media tray.

A transport apparatus includes a mounting section on which a medium is to be mounted, a drive section configured to drive the mounting section in a moving direction and a protection section configured to be switched between a protection state for protecting the drive section and a release state for releasing protection of the drive section. The mounting section has a driven section that engages with the drive section and is driven by the drive section. When the driven section driven by the drive section engages with the drive section, the protection section is in the release state, and when the driven section does not engage with the drive section, the protection section is in the protection state.
