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 sheet accommodating apparatus includes a main body portion, a loading portion that is provided in the main body portion and supports a portion of a sheet loaded thereon from below, a lifting unit that lifts the loading portion, and a supporting portion that is connected to the main body portion and supports another portion of the sheet from below during a process in which the loading portion is lifted.

An image reading apparatus includes a stacking portion, a feeding unit, a reading unit, and a discharge portion provided below the stacking portion. The feeding unit feeds a sheet stacked on the stacking portion in a feeding direction. The reading unit reads an image on the fed sheet and the discharge portion discharges the read sheet. The stacking portion includes first and second support surfaces that support the sheet and first and second regulating units to regulate a position of the sheet in a widthwise direction using two opposing ends of the sheet. The second support surface is retractable from a predetermined section above the discharge portion. The first support surface includes a downstream support portion that supports the sheet on a downstream side of the predetermined section in the feeding direction. A part of the second regulating surface is positioned on the downstream support portion.

In some examples, a substrate handling system includes a sheet processing machine and at least one alignment device that includes at least four stops. At least one stop is configured as a front stop, at least one stop is configured as a rear stop, and at least two stops are configured as lateral stops. The at least two lateral stops are arranged opposite one another, and the at least one front stop and the at least one rear stop are arranged opposite one another. The alignment device includes at least one support element that is configured as a propping element for propping at least one partial stack of sheets in the alignment device. Further, at least one respective support element is arranged at the at least two lateral stops and at the at least one rear stop.

A medium conveying apparatus includes a main body, a paper ejection tray main body that is supported by the main body and that is arranged at a paper ejection tray unfolding position or a paper ejection tray storage position, an extension member that is supported by the paper ejection tray main body and that is arranged at an expansion position or a contraction position, a cover that is supported by the main body and that is arranged at an opening position or a closing position, and a contact member that is fixed to the cover, wherein the cover is arranged at a midway position between the opening position and the closing position when the paper ejection tray main body is arranged at the paper ejection tray storage position and when the extension member is not arranged at the contraction position and is in contact with the contact member.

A sheet feeding device includes a sheet stacking unit, a long sheet stacking unit, a first guide, a first detector, and a closing unit. The sheet stacking unit is movable up and down. Sheets are stacked on the sheet stacking unit. The long sheet stacking unit is detachably mounted on the sheet stacking unit. Long sheets are stacked on the long sheet stacking unit. The first guide is movable along a feeding direction through a groove. The first guide is deformable into a shape that does not interfere with the long sheet stacking unit. The first guide guides a rear end portion of the sheets in the feeding direction. The first detector is provided in the first guide. The first detector detects the sheets stacked on the sheet stacking unit. The closing unit is detachably attached to the groove in the sheet stacking unit. The closing unit closes the groove.

According to examples, an apparatus may include an input tray coupled to a media path and an output tray to receive media from the media path. The output tray may be automatically positioned to an open position based on the media being inputted into the input tray. A movable section may be movably coupled to the output tray. In some examples, the movable section may automatically move relative to the output tray based on the output tray being automatically positioned to the open position.

A medium discharging device includes a first tray, a second tray receiving a medium from the first tray, a supporter which is configured to be displaced from a retreat position in the first tray and an advance position above the second tray and which supports the medium, an aligner which is provided in the supporter and that aligns a first end portion which is an upstream end portion in a discharge direction of the medium supported by the supporter, to be displaced together with the supporter, and a restrictor configured to be displaced between a restriction position where an upstream movement of the first end portion of the medium in a position of the aligner in the discharge direction and a non-restriction position where the movement is not restricted, when the supporter is in the advance position.

A document conveyance device includes a sheet feeding tray, a conveyance mechanism, a discharge tray, a document pressing member and a supporting mechanism. The document pressing member comes into contact with an upper face of the document discharged from a conveyance path and presses the document downward. The supporting mechanism is configured to be provided in the sheet feeding tray, to support the document pressing member, to allow a shifting of the document pressing member according to an operation for shifting the document pressing member in a discharge direction of the document or an opposite direction to the discharge direction and to inhibit the shifting of the document pressing member against a force applied to the document pressing member by the discharged document.
