ABSTRACT:
In a non-printing state, a cap is moved toward an ink jet nozzle of a head, for sealing the same. Immediately before the cap comes into contact with the jet nozzle, a gear is rotated by a motor to drive a piston, for sucking air from the interior of the cap by a suction pump consisting of the piston and a cylinder. This sucking operation is continued until the cap comes into close contact with the jet nozzle, for sucking the ink from the head.
