  • Patent number: 10618324
    Abstract: A printing apparatus includes a plurality of belt rollers that rotate, a direction in which a rotation axis of each belt rollers extends being a width direction that intersects a transport direction of a medium; a transporting belt that, while wound across the plurality of belt rollers, rotate to transport the medium in the transport direction; a print head that performs printing on the medium transported by the transporting belt; and a control unit that rotates the transporting belt while in a state in which an unrotated state of the transporting belt has continued for a predetermined period. When a rotation position of the transporting belt after application of power and before rotating the transporting belt is referred to as an initial rotation position, in a case in which a rotation of the transporting belt is to be stopped, the control unit stops the transporting belt at a rotation position that is different from the initial rotation position.

  • Patent number: 10343422
    Abstract: A recording apparatus includes a belt conveyor unit that can be switched between a first state in which at least a portion of the belt outer surface of a conveyor belt is located at a recording position at which a line head performs recording and a second state in which the belt outer surface is located more distant than the recording position from the line head. The recording apparatus also includes a wiping device that is in contact with the belt outer surface and wipes the belt outer surface. The belt conveyor unit is switched from the second state to the first state after carrying out of a preliminary operation in which the conveyor belt is moved over a predetermined distance in a reverse direction opposite to a normal direction in which the conveyor belt transports a sheet.

  • Patent number: 9789716
    Abstract: An ink jet printer includes a cleaning blade that cleans the surface of a transport belt that attracts a sheet of recording paper by electrostatic adsorption and transports the attracted recording paper, and a pressing roller. The width of the cleaning blade is smaller than the width of the pressing roller that is located downstream of the cleaning blade, and thus, ink, paper dust, and the like that have escapes from both ends of the cleaning blade to the outside and have not been wiped off are caught by the pressing roller.
