An image forming apparatus includes a sheet storage unit including a sheet tray on which one or more sheets are to be stacked, a sensor configured to detect that the sheet storage unit is being operated, and a processor configured to execute a predetermined process after the sensor detects that the sheet storage unit has been operated, and a predetermined condition relating to an occurrence of the sheet conveyance error is satisfied.

In a case where a skew of a document being conveyed is detected by a detection unit, an image reading apparatus notifies that documents having different sheet widths may be included in documents stacked on a stacking unit.

A sheet remover includes a pair of insertion-part formers and a pair of through-part formers. The pair of insertion-part formers forms an insertion part between the pair of insertion-part formers into which a sheet is inserted. At least one of the pair of insertion-part formers includes an inclined portion inclined in a direction in which a width of the insertion part in a thickness direction of the sheet decreases in a sheet insertion direction in which the sheet is inserted. The pair of through-part formers forms a through part between the pair of through-part formers through which the sheet is inserted. The through part is located downstream from the insertion part in the sheet insertion direction.

The present invention is to provide a sheet conveying apparatus capable of reliably detecting a full-load state of a storage section for storing sheets discharged from a sheet conveyance path when an abnormality such as multi feed is detected, a sheet feed apparatus is provided with a multi feed sheet storage section disposed below a common conveyance path to store multi-fed sheets with multi feed detected, and a flap member rotating between a first rotation position for supporting a sheet in the common conveyance path to be able to convey to the downstream side in a conveyance direction, and a second rotation position for guiding to the multi feed sheet storage section, and determines that the multi feed sheet storage section is in a full-load state in detecting that the flap member does not return to the first rotation position.

A printing apparatus includes a feeding roller, a conveyance roller, a first driving unit configured to drive the conveyance roller, a second driving unit configured to drive the feeding roller, a control unit configured to control the first and second driving units, a detection unit configured to detect an error related to the second driving unit, and a determination unit configured to determine, when the detection unit has detected the error related to the second driving unit, whether to continue the conveyance of a first print medium based on a leading edge position of a second print medium. In a case in which an error is detected by the detection unit, the control unit controls the conveyance of the first print medium by the conveyance roller based on a determination result of the determination unit.

A sheet conveyance device includes a sheet receiving part, a first discharge part, a sheet conveyance path, an escape conveyance path, a branch guide, an escape tray, a second discharge part, and a first sheet detection part. When a device failure occurs, the branch guide switches the conveyance direction such that the sheet remaining on the sheet conveyance path is discharged on the escape tray by the second discharge part, through the escape conveyance path sequentially. Then, the second discharge part stops a discharging of the sheet in a state where the sheet remains in the second discharge part when the sheet is a last sheet to be conveyed to the escape tray. Then, a receiving of a new sheet to the sheet receiving part from the image forming apparatus is inhibited while the first sheet detection part detects the last sheet.

In a case in which an error is detected by the detection unit, the control unit controls the conveyance of the first print medium by the conveyance roller based on a determination result of the determination unit.

An image forming apparatus includes an image formation engine configured to form an image on a sheet, and a re-conveyer configured to convey the sheet having an image formed on one surface thereof by the image formation engine to the image formation engine again along a re-conveying path. The re-conveyer includes a conveying roller configured to convey the sheet in a re-conveying direction toward the image formation engine, a first guide member configured to be swingable between a first position at which the first guide member defines a portion of the re-conveying path upstream of the conveying roller in the re-conveying direction and guides the sheet to the conveying roller and a second position for exposing the potion of the re-conveying path, and a support member configured to swingably support the first guide member and rotatably support the conveying roller.
