摘要:
The liquid ejecting apparatus includes nozzles which eject ink, an ink flow path which supplies ink from the upstream side toward the downstream side, a maintenance pump capable of suctioning and discharging ink from the ink flow path, a one-way valve which is opened in accordance with decompression on the downstream side, thereby allowing passage of ink from the upstream side to the downstream side, and a control unit which controls the driving of the maintenance pump, thereby performing a cleaning process, wherein the control unit makes the maintenance pump suction ink from a pressure-changing position in the ink flow path by performing the suction driving of the maintenance pump after making the maintenance pump discharge ink from the pressure-changing position in the ink flow path into the ink flow path by performing the discharge driving of the maintenance pump.
