A fold-enforcing assembly includes a fold-enforcing device, a moving device to move the fold-enforcing device in a direction of a fold of a sheet bundle, and control circuitry. The fold-enforcing device includes a pressing member pair to nip and press the fold of the sheet bundle in a direction of thickness, a pressing mechanism to pressurize and depressurize the pressing member pair, and a driver to drive the pressing mechanism. Controlled by the control circuitry, the moving device moves the fold-enforcing device in accordance with a size of the sheet bundle in the direction of the fold; pressing mechanism pressurizes the pressing member pair to press a first end portion of the sheet bundle in the direction of the fold; the moving device moves the fold-enforcing device to a second end portion of the sheet bundle; and pressing mechanism depressurizes the pressing member pair in the second end portion.

A medium discharging device includes a discharge roller pair that discharges a medium, a discharge tray disposed below the discharge roller pair in a vertical direction and having a placement surface on which the discharged medium is placed, and a guide member that is advanced and retracted between an advanced position where the guide member is advanced inward in a width direction from opposite sides in the width direction intersecting a discharge direction of the medium and a retracted position where the guide member is retracted to an end portion position side in the width direction. When the guide member is disposed at the advanced position, an upstream side end portion of the guide member in the discharge direction is disposed between a discharge position by the discharge roller pair and a position of the placement surface of the discharge tray, in the vertical direction.

A transport mechanism includes a transport belt in which holes are formed and a suction clinging mechanism. The transport mechanism transports the medium in the first transporting direction, and when the upstream edge reaches a switching position, the transport mechanism transports the medium in the second transporting direction and stacks the medium in a stacker. The suction clinging mechanism includes an opening of a first suction chamber and an opening of a second suction chamber, and the opening of the first suction chamber is located downstream of the opening of the second suction chamber in the first transporting direction. The switching position is located upstream of the opening of the first suction chamber in the first transporting direction. In the first transporting direction, the distance from the switching position to the opening of the first suction chamber is longer than the length of each hole.

A scanner for removing paperclips from a sheaf of papers, with a paper lifting tray operable to move the sheaf of papers in a vertical direction, a pushdown bar configured to move in a vertical direction and make contact with the sheaf of papers on the paper lifting tray and apply a force in an opposite direction from the direction in which the paper lifting tray moves, the force being sufficient to hold the sheaf of papers in place, and with a removal bar configured to move in a direction that is coplanar with the paper lifting tray and orthogonal to the vertical direction, wherein the removal bar is configured to come into contact with the sheaf of papers and push a paperclip off of the sheaf of papers.

A sheet bundle discharging apparatus, including: a guide unit configured to guide a sheet bundle with a spine as a leading end; a receiving unit configured to receive the spine of the sheet bundle guided by the guide unit; and a discharging unit configured to discharge the sheet bundle, wherein the receiving unit includes: a first surface configured to receive the spine at a first position; a second surface configured to push the sheet bundle in a rotation direction of the receiving unit; and a third surface configured to regulate a movement of the sheet bundle in the rotation direction while the receiving unit rotates from the first position to a second position, and wherein a friction coefficient between the sheet bundle and the third surface in a direction away from the first surface is larger than a friction coefficient between the first surface and the sheet bundle.

A printing device includes, in one example, a media output system including a mezzanine level including a plurality of media support members, the mezzanine level being intermediate to a floor level and a media output level; wherein the plurality of media support members move orthogonally relative to a print media path so that a number of finishing processes may be performed on print media accumulated on the number of media support members.

A media folding device includes a stacking portion on which media transported from an introduction path are placed; a folding roller pair that folds the media at a folding position after the media have been stacked in the stacking portion; and a bend forming mechanism that includes a first abutting portion configured to abut against a front end of the media, which are stacked in the stacking portion, in a transport direction, and a second abutting portion that is configured to abut against a rear end of the media, which are stacked in the stacking portion, in the transport direction, and that causes the folding position of the media to be nipped by the folding roller pair the folding roller pair by shortening the relative distance between the first abutting portion and the second abutting portion to bend the media toward the folding roller pair.

Provided are systems and methods for identifying, isolating, and/or aligning sheets. An identification system can facilitate accurate identification of a sheet by (i) vacating one or more components of the system that are not the sheet from a zone of detection, and/or (ii) determining a reference axis of the sheet. An isolation system can facilitate accurate isolation of a sheet by (i) providing targeted air flow, and/or (ii) introducing a wave into the sheet. Identification systems and/or isolation systems described herein may facilitate isolation of sheets that were previously fastened together by one or more fasteners. An alignment system can facilitate accurate alignment of a first sheet at an upstream location relative to a second sheet at a downstream location via machine learning.

According to examples, a printing apparatus may include an output bin that is laterally translatable between a retracted position and an extended position. The printing apparatus may also include a sensor to detect a height of a stack of media on the output bin while the output bin is in the retracted position and a controller. The controller may determine whether the detected height of the stack of media on the output bin exceeds a certain level and in response to a determination that the detected height of the stack of media exceeds the certain level, laterally translate the output bin from the retracted position to the extended position.

A medium conveying apparatus includes a first conveying path, a second conveying path that is connected to the first conveying path, a third conveying path that is connected to the first conveying path and the second conveying path, and a skew corrector that blocks a first space between the first conveying path and the second conveying path when a medium conveyed along the first conveying path is skewed, and retreats from the first space when the medium is not skewed, wherein the skew corrector retreats from a second space between the second conveying path and the third conveying path when blocking the first space, and blocks the third space between the first conveying path and the third conveying path when retreating from the first space.
