In an image forming apparatus, a sheet is guided into a first conveyor path or a second conveyor path selectively when a first cover is in a closed position, and is ejected onto the first cover when the first cover is in an open position. Upon power-up, a controller causes a first conveyor roller to rotate but if the first cover is in the open position, when a sheet sensor detects a sheet, the controller does not cause a second conveyor roller to rotate, and causes a flapper to swing from a first position to a second position, and when a front end of the sheet reaches a position downstream of an upstream end of the flapper in a conveyance direction of the sheet conveyed by the first conveyor roller, the controller causes the flapper to swing from the second position to the first position.

A medium processing device includes a conveyance guide that forms first, second and third conveyance paths that intersect, a blade configured to be rotatable around a blade center point, and that switches a conveyance route of the medium by connecting any two of the three conveyance paths with each other, and a first pair, second pair and third pair of conveyance rollers that are rotatable and are configured to hand off the medium between two conveyance paths connected by the blade. The first pair of conveyance rollers includes a first roller and a second roller. The second roller is closer than the first roller to the third pair of conveyance rollers. A radius of the second roller is larger than a radius of the first roller. A first center holding distance is different from one or both of a second center holding distance and a third center holding distance.

In an image forming apparatus, a tray having first and second receiving portions is configured to move between a first position, at which at least part of the tray is positioned inside an apparatus body, and a second position, at which the tray is outside the apparatus body. The tray in the first position allows a first recording medium to be conveyed from the first receiving portion. When the tray is in the first position, the second receiving portion is configured to move between a third position, which is at an upstream side relative to a first opening of the apparatus body in a second direction, and a fourth position, which is at a downstream side relative to the third position in the second direction. The second receiving portion at the third position allows a second recording medium to be conveyed from the second receiving portion in the second direction.

A sheet processing apparatus laminates a partially joined two-ply sheet and a sheet medium inserted in the two-ply sheet. The sheet processing apparatus includes a heat presser, an information acquisition device, and control circuitry. The heat presser heats and presses the two-ply sheet and the sheet medium. The information acquisition device acquires information on the two-ply sheet and the sheet medium. The control circuitry sets a fixing temperature of the heat presser in accordance with the information of the two-ply sheet and the sheet medium acquired by the information acquisition device.

A transportation apparatus includes a plurality of transportation members that are arranged in a transportation direction for a medium and transport the medium, a plurality of actuators that drive the plurality of transportation members, and a processor that controls the plurality of actuators in such a manner as to increase transportation velocities of the plurality of actuators in order from actuators for driving transportation members on a downstream side in the transportation direction to actuators for driving transportation members on an upstream side in the transportation direction.

A recording apparatus including a recording head that performs recording, a feed roller that feeds out a set medium, a transport driving roller that transports the medium, which is fed out by the feed roller, towards an opposing position that opposes the recording head, and an auxiliary roller provided between the feed roller and the transport driving roller, the auxiliary roller assisting transportation of the medium. When the apparatus is seen from a side of the apparatus, the auxiliary roller overlaps the feed roller in a height direction of the apparatus.

An image forming apparatus includes an image forming device, a transport route, a purge transport route, an image forming transport route, a transport roller, and a blowing machine. The image forming device forms an image on a sheet. The transport route extends to a predetermined position. The purge transport route extends to a downstream side in a sheet transport direction, from the predetermined position. The image forming transport route is branched from the purge transport route at the predetermined position, and extends toward the image forming device. The transport roller transports the sheet along the transport route, and along one of the purge transport route and the image forming transport route. The blowing machine delivers the sheet to one of the purge transport route and the image forming transport route, by blowing air to the sheet being transported along the transport route.

A printing apparatus includes: a printing section; a print conveyor conveying a medium in the printing section; a constant-speed conveyor conveying the medium at a variable constant conveying speed in a circulation route for duplex printing; a registration roller pair against which the medium to be conveyed to the printing section is caused to abut; and a processor determining a conveyance schedule for the medium based on at least one of a first conveyance route length between a downstream end portion in a conveying direction of the print conveyor and an upstream end portion in the conveying direction of the constant-speed conveyor and a second conveyance route length between a downstream end portion in the conveying direction of the constant-speed conveyor and the registration roller pair, and a medium length in the conveying direction of the medium.
