To eliminate a separate cleaning roller to clean a forme cylinder and in application roller in a printing machine system, and utilize existing rollers of the damping system to apply cleaning fluid, a support lever (8, 26) axially journals and retains a damping liquid application roller (1) and a damping liquid transport roller (2); a pivot lever (11) is pivotably coupled to the supply lever (8, 26), and a guide arrangement is provided, for example formed by a link system (14, 15, 16) or a cam track and cam control element (27, 28) to control movement of the support lever under control of an operating element, such as a solenoid or a piston-cylinder arrangement (13). Movement of the support lever is controlled by the guide means between a first position a first position, in which the damping liquid application roller is engaged on the forme cylinder (4) and the damping liquid transport roller (2) is in surface engagement with the damping liquid application roller and the liquid supply roller and a second position, in which the damping liquid application roller is in liquid transfer contact with the cleaning fluid supply means (18) and the transport roller (2) is in engagement with the ink application roller (5).
