A recording device includes a transport section that transports a medium in a transport direction along a transport path, a recording section that records an image on the medium transported by the transport section, a cutter unit including a cutter blade for processing the medium in the transport path, and a cutter carriage configured to move the cutter unit in a widthwise direction intersecting the transport direction, wherein the cutter unit is attachable to and detachable from the cutter carriage, and the cutter unit enters an exposed state in which the cutter blade becomes exposed in accordance with an attachment operation of attaching the cutter unit to the cutter carriage, and enters a non-exposed state in which the cutter blade is not exposed in accordance with a detachment operation of detaching the cutter unit from the cutter carriage.

An image forming device includes an image forming unit configured to form an image on a sheet, a fixing unit configured to fix the image on the sheet, the fixing unit including heating rotation body, a heater configured to heat the heating rotation body, and a pressure rotation body configured to form a nip portion between the heating rotation body and the pressure rotation body, a discharge roller disposed downstream of the fixing unit in a conveying direction of the sheet, and configured to discharge the sheet, a main motor configured to transmit a drive force to at least one of the heating rotation body or the pressure rotation body, a cutter disposed downstream of the fixing unit in the conveying direction, and configured to cut the sheet, and a controller.

An image forming device includes a device main body including a conveying path of a sheet, a fixing unit configured to fix an image formed on the sheet onto the sheet, the fixing unit including a heating rotor, and a pressure rotor in which a nip is formed between the heating rotor and the pressure rotor, a first discharge roller located at a downstream side of the fixing unit in a conveying direction of the sheet along the conveying path, and configured to convey the sheet, a second discharge roller located at a downstream side of the first discharge roller in the conveying direction, and configured to discharge the sheet conveyed by the first discharge roller to an outside of the device main body.

A perforation forming machine including, a biasing mechanism that constantly biases a cutter toward a receiving base; and a cam configured to form a state in which the cutter can be pressed against the receiving base by a biasing force and a state in which the cutter is separated from the receiving base against the biasing force. A presser is disposed in a state in which the perforating blade is separated from the receiving base via the sheet and the presser is configured so as to be able to press the cutter toward the receiving base. In a case in which the perforating blade is separated from the receiving base via the sheet, the cam is made to abut against the presser to displace the cutter toward the receiving base, and the perforating blade is pressed down to a height at which the perforating blade penetrates the sheet.

An image forming system includes an image forming mechanism configured to form an image on a recording medium and a processor configured to stop rotation of a rotating member in the image forming mechanism when time, calculated by subtracting time required for image quality adjustment of an image to be formed from time required for post-processing of a recording medium on which an image is formed in a post-processing apparatus, is longer than set threshold time.

A sheet processing apparatus processes a sheet by using a rotary blade. The sheet processing apparatus includes: a rotary blade unit that supports the rotary blade such that the rotary blade is rotatable on a rotation shaft and movable in an axial direction of the rotation shaft; a guide member that is supported by the rotation shaft and that guides part of the sheet; and a rotation stopper that prevents rotation of the guide member. The rotation stopper is mounted on the rotary blade unit.

An image forming system includes: an image forming apparatus that forms an image on a recording medium; a relay transporter that transports the recording medium on which the image is formed by the image forming apparatus; a post-processing apparatus including a collecting container that collects a recording medium, the post-processing apparatus performing post-processing on the recording medium transported by the relay transporter; and at least one processor configured to stop transport of a recording medium when a paper jam occurs in the post-processing apparatus and, if a remaining recording medium is present in the relay transporter when the paper jam is cleared and the transport of the recording medium is restarted, cause the remaining recording medium to be collected by the collecting container.

A post-processing apparatus includes a cutter that cuts an edge of a transported recording medium, a collection container that is disposed below the cutter and that collects the edge when the edge cut by the cutter falls downward, and a blower that blows gas into the collection container.

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.
