A fold-enhancing device includes a pressing member, at least one retaining member, and a moving mechanism. The pressing member presses against a fold line of a recording-medium bundle folded into a booklet shape. The recording-medium bundle is obtained by stacking multiple sheets of recording media. The retaining member retains the recording-medium bundle and is provided at a position located away from the fold line in a direction intersecting the fold line and not in contact with the pressing member. The moving mechanism moves the pressing member and the retaining member in a direction extending along the fold line.

An image forming system includes an image forming apparatus, a sheet processing device, and control circuitry. The image forming apparatus forms an image on a sheet. The sheet processing device performs post-processing on the sheet. The sheet processing device includes a first conveyance path through which the sheet is conveyed and subjected to the post-processing and a second conveyance path through which the sheet is conveyed without the post-processing. In response to an instruction of print jobs including both a print job of one or N copies subjected to the post-processing and a print job not subjected to the post-processing, the circuitry executes the job not subjected to the post-processing during execution of an M-th copy of the job subjected to the post-processing and causes the sheet to be conveyed through the second conveyance path, where N is two or greater and M satisfies 1≤M<N.

To enable highly accurate fold processing by properly moving a sheet that has been subjected to fold processing. In a sheet processing apparatus that that performs fold processing in such a manner as to apply first fold processing to a sheet and then apply second fold processing at a position different from a fold line formed in the first fold processing so as to make one end of the sheet folded in the first fold processing lie inside the folded sheet, the first fold processing is applied to a sheet conveyed to an intermediate tray by a fold roller pair and, when a regulating stopper is moved to move the folded sheet that has been subjected to the first fold processing to a predetermined position of the intermediate tray, the folded sheet is gripped by a grip unit.

To prevent displacement of first fold positions and collapse of discharged and stacked sheets when sheet fold processing is performed a plurality of times for each sheet. First fold processing is applied to a sheet conveyed to a conveying path by a rotating body pair 22. The sheet that has been subjected to the first fold processing is fed back to the conveying path while a first fold line is being opened. Then, second fold processing is applied to the sheet that has been fed back to the conveying path by the rotating body pair 22. The resultant sheet is discharged with the first fold line opened.

A finisher assembly of a multifunction peripheral includes a vertically oriented stapler and a paper transport motor. When the paper transport motor rotates in the forward direction, printed pages from the print engine of the multifunction peripheral are received via a paper chute and a feed assist roller urges the printed pages into a vertical paper accumulation cache basin. Rotation of the paper transport motor also opens a biasing plate allowing the pages to freely enter the cache basin. Once all of the pages of the print job are in the cache basin, the paper transport motor rotates in the reverse direction causing the biasing plate to bias the printed pages, in the cache basin, against a registration surface of the vertically oriented stapler unit. The pages of the print job are stapled together the stapled print job is moved to the paper tray for collection by a user.

The aligning device receives a sheet conveyed in a sheet conveyance direction in a stackable manner and aligns a position of the sheet in the sheet conveyance direction. The moving mechanism moves the sheet aligned by the aligning device in the sheet conveyance direction together with the aligning device. The controller selectively executes a first mode in which first post-processing is performed on the sheet and then second post-processing is performed on the sheet and a second mode in which the second post-processing is performed on the sheet without performing the first post-processing on the sheet. The controller, in response to a selection of the first mode or the second mode, causes the moving mechanism to adjust a position of the aligning device in the sheet conveyance direction before the aligning device receives the sheet as a target of the first post-processing or the second post-processing, respectively.

A sheet stacker includes a pair of sheet holders, a sheet leading-edge aligner, a sheet stacking member, and control circuitry. A downstream side of the pair of sheet holders in a conveyance direction of a conveyed sheet is lowered along the conveyance direction. Each one of the pair of sheet holders is movable in an orthogonal direction to the conveyance direction. The pair of sheet holders hold both side-end portions of the sheet in the orthogonal direction. The sheet stacking member is disposed below the pair of sheet holders. A downstream side of the sheet stacking member in the conveyance direction is lowered along the conveyance direction. The sheet stacking member stacks the sheet dropped from the pair of sheet holders after a leading edge of the sheet is aligned by the leading-edge aligner. The control circuitry controls operations of the leading-edge aligner and the pair of sheet holders.

A value note cassette includes a first storage area for storing first notes of value of a first value note type. The first notes of value are storable in the first storage area in a first orientation. The value note cassette also includes a second storage area for storing second notes of value of a second value note type. The second storage area is separate from the first storage area. The second notes of value are storable in the second storage area in a second orientation. The first orientation is orthogonal to the second orientation.
