A printing apparatus includes a print section, a supply path, a correction roller pair, an adjusting mechanism and a controller. The print section is configured to perform printing on a medium. The supply path is configured to supply the medium to the print section. The correction roller pair is configured to enable the medium transported on the supply path to strike the correction roller pair to correct skewing of the medium. The adjusting mechanism adjusts a nip load applied to the correction roller pair. The controller is configured to control the adjusting mechanism based on print job information. The correction roller pair includes a driving roller that has a plurality of convex portions disposed on a peripheral surface along a circumferential direction of the driving roller and a driven roller that is disposed to face the driving roller to be driven by the driving roller.

A printing device including: a first conveyance path and a second conveyance path configured to conveying print media; a skew correction unit configured to correct skewing of the print medium conveyed along the first conveyance path; and a print unit configured to print on the print medium conveyed on the first conveyance path or the second conveyance path; the first conveyance path and the second conveyance path merging downstream of the skew correction unit; print media conveyed from the second conveyance path.

A print system includes a first printer which performs printing on a sheet while conveying the sheet and a second printer which receives the sheet conveyed from the first printer and performs printing on the sheet while conveying the sheet. The second printer includes a second printing unit, a second registration roller, a second pre-registration roller, a sheet detector, and a second controller. The second controller controls an operation of the second pre-registration roller and an operation of the second registration roller based on a timing of a detection of the sheet by the sheet detector.

An image forming apparatus performs skew correction by bringing a leading end of a conveyed sheet in contact with a registration roller pair being in a stopped state and by forming a first loop with a loop roller pair, and thereafter, refeeds the sheet to an image former by adjusting timing. In a case of feeding a sheet with a length equal to or longer than a prescribed length, after having formed the first loop, the image forming apparatus forms a second loop in a loop accommodator that is disposed on an upstream side than the loop roller pair and accommodates a formed loop.

An image forming apparatus is provided including a drive source, a switching member, a drive force transmitter, a clutch, a controller, etc. The drive source drives a conveyer to rotate either normally or reversely. The switching member is swingable between an evacuation position and a striking position as a shaft rotates. The drive force transmitter transmits a drive force from the drive source to both the conveyer and the shaft. The clutch transmits the drive force to the shaft when being connected, and holds the switching member at the striking or evacuation position when being disconnected. The controller controls the drive source and the clutch such that the conveyer normally rotates to convey a manually-inserted recording medium from a manual conveyance path to an ejector and that the switching member swings from the evacuation position to the striking position, based on a signal indicating that the set position is wrong.
