Abstract
An ink jet printing apparatus has a carrier that mounts a print head for movement between a printing region and a non-printing region by rotation of a lead screw. A cap in the non-printing region has two adjacent chambers and is moved between a contact position, in which the cap covers a discharge port forming surface of the print head, and a retracted position. One cap chamber seals the discharge port from the atmosphere and the other is connected to a suction pump to apply suction to a discharge port in the print head. In one embodiment the area of the cap in contact with the print head when the suction chamber is covering the discharge port forming surface is smaller than the area when the sealing chamber is covering it. Rotational movement of the lead screw can be used to move the cap and operate the suction pump.
