In some examples, a system is disclosed that includes a roller assembly for a printer. The roller assembly includes a pressure roller, a belt coupled, a drive assembly to rotate the pressure roller and to urge the pressure roller into the belt, a heater to apply heat to the belt, and a temperature sensor to detect a temperature of the belt. In addition, the roller assembly includes a controller to increase a pressure applied to the pressure roller from a first to a second pressure in pressure in response to a temperature of the belt being greater than or equal to a first temperature threshold. Also, the controller is to initiate an advance of a print media to contact the belt in response to the temperature of the belt being greater than or equal to a second, higher temperature threshold.

A conveyance apparatus includes a bearing rotator, an entrance rotator, an exit rotator, a first driver circuit, a downstream conveyor, a second driver circuit, and a recording medium detector. The entrance rotator receives a recording medium at a first position. The downstream conveyor receives the medium at a second position. As a process of removing the medium, the first driver circuit starts rotation operation after the second driver circuit starts driving the downstream conveyor and rotates the rotators for not less than a period of time for the medium to be conveyed from the first position to the second position. The second driver circuit continues driving the downstream conveyor for not less than a period of time for the medium to be conveyed from the second position to a position at which the medium is detected after the rotation operation of the first driver circuit is stopped.

A cleaning device includes a separation and contact mechanism that separates a web from a conveyance roller and brings the web into contact with the conveyance roller, and a controller. The controller includes a conveyed sheet number determination unit and a separation and contact control unit. The conveyed sheet number determination unit monitors a conveyed sheet number of both-surface image forming sheets where image forming processing is applied to both a first surface and a second surface with respect to the sheets conveyed by the conveyance roller, and determines whether or not a cumulative value of the conveyed sheet number has reached a predetermined threshold value. The separation and contact control unit controls the separation and contact mechanism so as to allow the web to be pressed to the conveyance roller by a pressing roller when the cumulative value of the conveyed sheet number has reached the threshold value.

A recording device includes a recording head, a transport roller set, and a controller that controls a driving source that drives a transport driving roller. The controller judges whether a rear end that is an upstream end of a medium in a transport direction crosses a kicking region set in a range present downstream of a nipping position of the transport roller set in a transport direction. When the controller judges that the rear end does not cross the kicking region, the controller adjusts a feeding amount for at least one of a plurality of transport operations to be performed until the rear end reaches the kicking region in such a manner that the rear end of the medium crosses the kicking region.

A printing apparatus includes a transportation roller that transports recording paper in a transporting direction, a head that performs printing on the recording paper, a cutter that has a second blade located at a position facing an opening located downstream in the transporting direction of the head and the transportation roller and a first blade configured to move from the opening to the second blade and configured to cut the recording paper together with the second blade, and a flap that has a shutter configured to open and close the opening and is configured to move between a first position and a second position, and when the first blade moves from the opening to the second blade, the flap moves from the first position to the second position, and the shutter opens the opening, and when the first blade moves away from the second blade, the flap moves from the second position to the first position, and the shutter closes the opening.

A medium conveying apparatus includes a medium tray, a feed roller, an upper guide, a movement sensor including an arm movably provided by the fed medium on the upper guide and on an upstream side of the feed roller, to generate a movement amount signal corresponding to a movement amount of the arm, a medium sensor to detect a presence of the medium at a predetermined position of the medium tray, a processor to determine whether a feeding abnormality of the medium has occurred based on the movement amount signal, detect a size of the medium placed on the medium tray based on a detection result by the medium sensor, and stop feeding of the medium by the feed roller when the processor determines that the feeding abnormality of the media has occurred and the detected size of the media is equal to or less than a predetermined size.

A second roller set is disposed separately from a first roller set in one direction of the conveyance direction, and includes an intermittent roller that generates, during one rotation, a conveyance enabled time of contacting the card and conveying the card and a conveyance disabled time of not contacting the card and not conveying the card. A third roller set is disposed separately from the second roller set. A reference guide wall receives abutments of a first end portion of the card and arranges a position of the card in the width direction at a reference position. An urging guide wall urges a second end portion of the card toward the reference guide wall by a first urging force. A support wall regulates a movement of the reference guide wall toward the urging guide wall at a position serving as the reference position.
