A medium processing apparatus includes an intermediate stacker on which media recorded by a recording apparatus are stacked, the recording apparatus including a liquid ejection head which performs recording by ejecting liquid to media and a maintenance apparatus which performs maintenance of the liquid ejection head, and a processor which executes a process on the media received by the intermediate stacker. The medium processing apparatus executes the process after a medium which is last recorded before the maintenance is stacked on the intermediate stacker.

A sheet folding system includes a plurality of sheet folding apparatuses configured to receive and perform a folding process on a sheet and circuitry configured to distribute sheets to the plurality of sheet folding apparatuses. Each of the plurality of sheet folding apparatuses includes a folding device configured to fold the sheet, a first conveyance passage configured to convey the sheet downstream in a sheet conveyance direction without passing through the folding device, a second conveyance passage configured to convey the sheet to the folding device, a third conveyance passage configured to convey the sheet from the folding device downstream in the sheet conveyance direction, and a junction between the first conveyance passage and the third conveyance passage. The circuitry controls sheet conveyance to prevent an interference, at the junction, between the sheet conveyed from the first conveyance passage and the sheet conveyed from the third conveyance passage.

An image forming apparatus that is capable of preventing discharged sheet adhesion while lowering degradation of productivity. A print unit prints an image on a sheet based on a print job. A fixing unit fixes the image primed on the sheet to the sheet. The sheet to which the image is fixed is discharged to a discharge tray. A counter counts discharged sheet number that is the number of sheets discharged to the discharge tray during a continuous print operation. A controller controls the print unit so as to lower productivity that is discharging sheet number per unit time in response to increase in the discharged sheet number counted by the counter and so as to recover the productivity in a case where the sheets discharged to the discharge tray are removed in a state where the productivity is lowered.

According to one embodiment, a post-processing apparatus includes a first sensor, a second sensor, and a control unit. The first sensor detects an object in a predetermined area in which a predetermined post-process is performed on a sheet conveyed from an image forming apparatus. The second sensor detects an object at a position closer to an opening in the area than the position of the first sensor with respect to the opening through which the sheet passes when the post-processed sheet is discharged from the area. When the second sensor detects an object before the first sensor detects the object, the control unit performs a predetermined process for preventing the occurrence of a failure.

A recording apparatus is provided with a transport roller pair which transports a medium toward a recorder, a feed roller which transports the medium toward the transport roller pair, and a controller which controls the transport roller pair and the feed roller. The controller is capable of executing a combined skew rectification mode which executes one of a first skew rectification operation in which a leading end of the medium abuts the transport roller pair using backward rotation of the transport roller pair and forward rotation of the feed roller and a second skew rectification operation in which the transport roller pair to rotate backward without driving the feed roller and discharges the leading end of the medium to the upstream side of the transport roller pair, and subsequently executes the other of the skew rectification operations.
