A recording apparatus includes a recording unit, a first transport path through which a medium is transported in a first direction during recording, a second transport path through which the medium after the recording is transported along a path that is different from the first transport path in a second direction, a discharge roller pair that is disposed at a downstream position of the recording unit and that is configured to be displaced between a nipping position and a separation position, and a flap that is disposed downstream of the recording unit. When the following medium is transported on the first transport path, the preceding medium is transported on the second transport path, and the respective media are disposed at a position of the discharge roller pair at the same time, the discharge roller pair is disposed at the separation position, and the flap is disposed at an advanced position.

A dual nip release mechanism includes: a rigid actuator body including a tail portion with a handle and a pivotally-mounted head portion having a nose member extending therefrom; a rocker arm pivotally mounted about a rocker arm shaft, the rocker arm having a proximal end for engagement with part of the nose member and a distal end engaged with a first shaft; and legs hingedly connected to the tail portion, each leg having a foot engaged with a second shaft and a heel for camming engagement with a fixed plate. During use, actuation of the handle causes simultaneous movement of the first and second shafts from a nip closed position to a nip open position via pivoting of the rocker arm and simultaneous camming engagement of the heel with the fixed plate.

A pinch roller mechanism includes a rail, a slider, a roller bracket, a spring, and a pinch roller. The rail extends in a first direction crossing the conveyance direction of a medium while being apart from a medium driving roller configured to convey the medium. The slider is supported by the rail to be movable along the rail. The roller bracket is supported by the slider to be movable with respect to the medium driving roller. The spring is provided between the slider and the roller bracket and biases the roller bracket toward the medium driving roller. The pinch roller is rotatably supported by the roller bracket while setting the axial direction in the first direction.

A printer includes a first holding shaft holding side pinch rollers and at least one center pinch roller, grit rollers moving a recording medium while holding the recording medium together with the side pinch rollers and together with the center pinch roller, and a rotator rotating the first holding shaft to cause the side pinch rollers and the center pinch roller to approach, or to be separated from, the grit rollers. The center pinch roller is movable in a direction to be separated from the recording medium, independently from the side pinch rollers.

A curl straightening device includes an endless belt, a curl straightening roller, a nip width adjusting mechanism, and a guide member. The curl straightening roller makes pressure contact with an outer peripheral surface of the endless belt, forming a nip portion, and straightens curl of the sheet which passes through the nip portion. The nip width adjusting mechanism moves the curl straightening roller in a direction away from or close to the endless belt so as to change a nip width. The mechanism includes a supporting holder of the curl straightening roller, and a rotationally moving portion that rotationally moves the roller supporting holder for moving the curl straightening roller. The guide member includes a pair of hanging members that are hung from both ends of the curl straightening roller so as to keep the guide member in constant position and posture relative to the curl straightening roller.

The curl straightening device includes supporting rollers, an endless belt, a curl straightening roller, and a contact member. The supporting rollers are disposed rotatably about a shaft extending in a direction orthogonal to a conveying direction of the sheet. The endless belt is stretched across the supporting rollers, and circulates in the conveying direction. The curl straightening roller makes contact with an outer peripheral surface of the endless belt between the supporting rollers so as to form a nip portion, and straightens curl of the sheet which passes through the nip portion. The nip portion is shaped so that the endless belt curves along a peripheral surface of the curl straightening roller. The contact member is disposed to oppose a center portion of the curl straightening roller in an axial direction, and makes contact with the curl straightening roller so as to prevent deformation of the curl straightening roller.

Systems, methods, and devices for mitigating print head dry out. In an example embodiment, a system can be implemented, which includes an arrangement of cross rollers and a registration transport for transporting one or more sheets for printing, and a steering mechanism that drives the sheet(s) into the opposing registration print edges of print heads on the registration transportation, wherein the cross rollers only engage when the sheet is being registered to the appropriate edge of the print heads, thereby allowing the print heads to be exercised prior to drying out. When one or more of the sheets are out of the nip, the nip disengages, thereby allowing the next sheet to be stirred on the opposing edge of the registration print heads. The opposing registration print heads comprise an inboard registration edge and an outboard registration edge.

Job types include a first job type in which a second process is performed after a first process and a second job type in which the first process is performed and the second process is not performed. In a printer, a recording medium is allowed to be sandwiched by a center pinching roller and driving rollers. A controller of the printer includes a first primary elevation controller that controls the center pinching roller such that the center pinching roller stays down on the driving rollers to hold the recording medium in performing the first process in the first job type and a first secondary elevation controller that controls the center pinching roller to move upward and stay away from the driving rollers in performing the first process in the second job type.

A recording device comprising a driving roller configured to be driven by receiving a drive force from a drive source and transport a medium in a transport direction, a frame located below the driving roller and including an attachment surface extending in a device height direction intersecting the transport direction, and a driving roller support member configured to support the driving roller. The driving roller support member is removably attached to the attachment surface.

A coating device includes a coating member, a nip forming member, a pair of conveying members, and circuitry. The nip forming member forms a coating nip together with the coating member. The pair of conveying members is opposed each other to nip and convey a recording medium to the coating nip. The circuitry is configured to cause the pair of conveying members to release nipping of the recording medium at timing when a leading end of the recording medium reaches the coating nip.
