  • Patent number: 10093117
    Abstract: A recording apparatus includes a transportation belt, a washing portion that washes the transportation belt, and a selection unit. The selection unit selects a transportation mode for transporting the recorded medium from among a washing transportation mode in which the transportation belt is transported while being washed by the washing portion, and a non-washing transportation mode in which the transportation belt is transported without being washed by the washing portion. The selection unit selects the transportation mode in accordance with a recording mode. The selection unit selects, as a transportation mode for use in transporting the recorded medium along with no recording operation after a recording operation onto the recorded medium has been brought to a halt, the washing transportation mode or the non-washing transportation mode, whichever has been selected in the recording operation having been brought to a halt.

  • Patent number: 8611776
    Abstract: A cleaning apparatus includes a first cleaning roller, and a second cleaning roller. The first cleaning roller is contrived to contact to a circumferential surface against a moving member to be cleaned and to apply a bias to the member to be cleaned while rotating such that the circumferential surface of the first cleaning roller moves in a same direction as the member to be cleaned moves. The second cleaning roller is contrived to contact to the member to be cleaned after the member has been cleaned by the first cleaning roller and to rotate such that a circumferential surface of the second cleaning roller moves in a direction opposite a direction in which the member being cleaned moves.
