A printing apparatus, comprises a first circuit board configured to control a first motor and a printing unit that performs printing to a print medium, a second circuit board configured to control a second motor, a sensor configured to output a sensor signal used to control the first motor and the second motor, and a signal line configured to input the sensor signal from the sensor to the first circuit board and the second circuit board.

A printer includes a record section, a discharge section, a mount section, a movable rib, a move section, and a control section. The record section records on a sheet by ejecting an ink to the sheet. The discharge section discharges the sheet. The mount section has a mount surface on which the sheet discharged is mounted. A movable rib is configured to protrude from the mount surface and supports the sheet. The dimension of the movable rib in an A-direction is larger than the dimension thereof in a Y-direction. The move section moves the movable rib in a C-direction. The control section controls, based on temperature and humidity information, movement of the movable rib made by the move section.

An image forming system includes a first unit, a second unit, and a third unit. The first unit includes an image forming unit that forms an image on a sheet fed from a feed unit. The second unit is arranged on a downstream side of the first unit and includes a cutting unit that cuts the sheet on which the image is formed by the image forming unit. The third unit is arranged on a downstream side of the second unit and includes a post-processing unit that post-processes the sheet cut by the cutting unit. A sheet cut to have a first size is discharged to a first discharge unit provided in the second unit. A sheet cut to have a second size larger than the first size is discharged to a second discharge unit provided in the third unit.

A method of handling a sheet defect error in a duplex print process, wherein media sheets are successively supplied along a feed path and are moved past a print engine where a first image is printed on a first side of each sheet in a first print pass, the sheets are then returned, via a duplex loop that contains a sheet flipping mechanism, to the feed path upstream of the print engine so that a second image can be printed on a second side of each sheet in a second print pass, the finished sheets being then discharged in a predetermined page sequence, and wherein, when a sheet defect is found a first print pass of a sheet, the defective sheet is diverted into an eject path downstream of the print engine, and a print pass for an immediate successor of the defective sheet is skipped. The subsequent semi-finished sheets are recirculated in the duplex loop while the supply of fresh sheets into the feed path is interrupted, and duplex printing is resumed during or after recirculating the subsequent semi-finished sheets.

A drive transferring unit includes a first roller, a second roller, a first clutch, a second clutch, a transferring section, and a control section. The first roller includes a first shaft section. The second roller includes a second shaft section. The first clutch switches between enabling transfer of a driving force to the first shaft section and interrupting transfer thereof. The second clutch switches between enabling transfer of the driving force to the second shaft section and interrupting transfer thereof. The transferring section transfers the driving force from one of the first roller and the second roller to the other. The control section selects between first control in which the first clutch is in the on state and the second clutch is in the off state and second control in which the second clutch is in the on state and the first clutch is in the off state.

A printing apparatus includes a supply unit configured to supply a print medium, an intermediate roller configured to transport the print medium, a transport roller configured to transport the print medium, a printing unit configured to print an image on the print medium, a reversing path configured to return, to the intermediate roller, the print medium which has been reversed front to back, and a control unit capable of first control for causing a second print medium supplied from the supply unit to overlap a first print medium being printed onto by the printing unit, and second control for causing a second print medium transported from the reversing path to overlap the first print medium being printed onto by the printing unit.

A medium transport unit includes an upstream route in which a print sheet is transported, a first switchback route, a second switchback route, a first guide route, a second guide route, a guide flap configured to switch the route so that the print sheet in the upstream route is transported either toward the first guide route or toward the second guide route, a first discharge route from which the print sheet in the first switchback route is discharged, a second discharge route from which the print sheet in the second switchback route is discharged, and a downstream route passing between the first switchback route and the second switchback route and having an upstream end connected to a junction of downstream ends of the first discharge route and the second discharge route.

A printing apparatus includes a divider disposed downstream of a print engine in a conveyance direction, and a controller. The controller causes a conveyor to convey a print medium until a planned dividing position of the print medium reaches a dividing position of the divider, when a first conveyance amount is larger than a second conveyance amount. The first conveyance amount corresponds to a print width for a printing process by the print engine. The second conveyance amount is calculated using a distance between a reference position and the dividing position and a distance between the reference position and the planned dividing position. After the planned dividing position of the print medium reaches the dividing position, the controller causes the divider to divide the print medium into first and second print media. The controller causes the conveyor to convey the second sheet to a printing position.

A printing apparatus includes a printing unit, a first conveyance unit configured to convey a print medium in a conveyance direction, a second conveyance unit configured to convey a print medium printed by the printing unit, on a downstream side in the conveyance direction of the first conveyance unit, and a control unit configured to perform reduction control of reducing an overlap amount of a preceding print medium and a succeeding print medium, from an overlap state in which the succeeding print medium overlaps a trailing edge of the preceding print medium. The reduction control includes control of conveying the preceding print medium conveyed by the second conveyance unit faster than the succeeding print medium conveyed by the first conveyance unit, in a state in which the first conveyance unit is capable of conveying the succeeding print medium.

A recording apparatus includes: a recording path passing a recorder performing recording by ejecting liquid onto a medium; a feeding path through which the medium is fed to the recording path; a discharge path through which the medium after recording performed thereon by the recorder is discharged; a reading path extending through a reader reading an image, provided independently of the recording path, the feeding path, and the discharge path and to which the medium with a recorded image being used to check a state of liquid ejection of the recorder recorded thereon is fed; and a switching portion switching between a first state in which a feeding direction of the medium after recording performed thereon by the recorder is set to a direction toward the reading path and a second state in which the feeding direction is set to a direction other than the direction toward the reading path.
