Ink jet recorder capable of reliably sealing ink jet nozzle

摘要

In a non-printing state, a cap (1) is moved toward an ink jet nozzle of a head (2), for sealing the same. Immediately before the cap (1) comes into contact with the jet nozzle, a gear (16) is rotated by a motor (10) to drive a piston (9), for sucking air from the interior of the cap (1) by a suction pump consisting of the piston (9) and a cylinder (15). This sucking operation is continued until the cap (1) comes into close contact with the jet nozzle, for sucking the ink from the head (2). <MATH>
