Abstract:
A liquid ejecting apparatus includes a liquid ejecting head, an ink supply tube that supplies ink to the liquid ejecting head, a pressure control valve that opens as a result of depressurization on the liquid ejecting head side, a check valve provided upstream from the pressure control valve, an ink circulation tube that is connected at both ends to the ink supply tube between the pressure control valve and the check valve, and a tube pump provided in the ink circulation tube; in this configuration, by providing at least one of an ink return tube and a liquid reservoir portion that is capable of holding liquid in a liquid flow channel in a pressurized state, a rise in pressure within a circulating flow channel caused by pump operations can be suppressed.
