Abstract: A cleaning device includes a controller configured to control cleaning of a conveyance roller by a web. The controller includes a take-up control unit and a web end determination unit. The take-up control unit controls the solenoid such that the web is taken up by rotatably driving the take-up roller in a state where the web is pressed to the conveyance roller. The web end determination unit determines whether or not an end of the web is exposed on a support roller by a take-up operation of the take-up roller. The web end determination unit determines that the end of the web is exposed on the support roller when a detection result of a detection unit is not changed in spite of a fact that supplying of electricity to the solenoid is performed.

Abstract: A cleaning device includes a cleaning unit and a unit moving mechanism. The cleaning unit brings a web into contact with a conveyance member rotating around an axis and removes foreign matter adhered to the conveyance member. The unit moving mechanism displaces the cleaning unit to a cleaning position where the web is brought into contact with the conveyance member and to a separation position where the web is separated away from the conveyance member. When the unit moving mechanism displaces the cleaning unit from the cleaning position to the separation position, the cleaning unit is displaced in a counter direction opposite to a rotational direction of the conveyance member on a contact face between the conveyance member and the web.

Abstract: A cleaning device includes a controller configured to control cleaning of a conveyance roller by a web. The controller includes a separation and contact control unit, a conveyance roller rotation control unit, and a take-up control unit. The separation and contact control unit is configured to control a separation and contact mechanism so as to allow the web to be pressed to the conveyance roller when the conveyance roller is in a non-conveyable state. The conveyance roller rotation control unit rotates the conveyance roller in a state where the web is pressed to the conveyance roller. The take-up control unit is configured to allow the take-up roller to perform a take-up operation of taking up the web by rotatably driving the take-up roller plural times at a predetermined time interval within a cleaning time set in advance in a state where the conveyance roller is being rotated.
