Abstract An impression drum 10 has gripper claws 12 which chuck the front edge of a sheet and only a drum peripheral section 10A extending between the gripper claws 12 sequentially set is cleaned each time in a first cleaning phase. In addition, a cleaning cloth 24 is sent in advance only in a specified cloth section 22, against a region of another drum peripheral section 10B extending between the gripper claws 12 to which the cleaning cloth 24 is not brought into contact. After at least the single turn of the impression drum 10, the other drum peripheral section is cleaned and at the same time, the cleaning cloth 24 is fed each time when one drum peripheral section already cleaned passes through a pressing element 20.
