PROBLEM TO BE SOLVED: To contrive to enhance controlling capability by a method wherein the number of actuations of an actuator is controlled at the washing position and at retreated position of a washing unit different from each other under the condition that the actuator for winding washing web is fixed to the frame side of a printer in a washing device for washing the peripheral. surface of a cylinder in various printers. SOLUTION: When the single washing button of a blanket cylinder is operated and a slow speed button is operated, the single washing of the blanket cylinder 20 is performed by a controlling device. At this time, by actuating an actuator 22 by turning on a solenoid valve for attaching and detaching a washing unit, the washing unit 33 is retreated from its washing position or brought into a unit escape state in order to wind washing cloth 36. Next, by actuating a cloth winding actuator 30, the washing cloth 36 is wound. At this time, since the cloth winding amount wound by a cloth winding roll 40 through the movement of the rod 31 of the winding actuator 30 by one time is l2 and the number of actuations of the actuator 30 is set to be (1+n) times, the cloth winding among L2 is turned to be L2 =l2×(1+n).
