A printing unit has print head with pressure bolt arranged along guided substrate. The cleaning elements are arranged on common rotational axis (9) which is moved by driving unit, such that Cleaning elements are pivoted between cleaning positions. The cleaning unit is located outside the displacement path between pressure bars and cleaning agent (5) in housing (11). The arc-shaped arrangement of pressure bolt is performed in printing unit, such that cleaning agents rests in first cleaning position by relative movement between pressure bars and cleaning element against print heads. |
