ABSTRACT:
A valve unit36is placed in an ink flow passage35between an ink cartridge8and a recording head7and can be controlled in association with the cleaning operation of the recording head7. Under the control of a drive controller, the valve unit36holds for a predetermined time a state in which negative pressure produced by a suction pump is accumulated, and is opened after the expiration of the predetermined time or is opened with the negative pressure accumulated and driving the suction pump is continued. The air bubbles remaining in a stuck state in the ink flow passage can be peeled from the ink flow passage together with an instantaneous fast ink flow produced as the valve unit36is opened, and the peeled air bubbles can be discharged, effectively from the ink flow passage following the subsequent ink flow.
