Abstract:
A liquid circulator includes an upstream tank having a first pressure sensor, an intermediate tank, a downstream tank having a second pressure sensor, a circulation route for circulating liquid through an liquid ejecting head, the downstream tank, the intermediate tank, and the upstream tank, a first pump on the circulation route between the intermediate tank and the upstream tank, a second pump on the circulation route between the downstream tank and the intermediate tank, a first drive circuit configured to apply a first driving pulse to the first pump, a second drive circuit configured to apply a second driving pulse to the second pump, a controlling unit configured to calculate a pressure fluctuation value of the circulation route based on pressure values measured by the first and second pressure sensors, and adjust a phase difference between the first and second driving pulses as to minimize the pressure fluctuation value.

Claim (Index 4):
The liquid circulator according to  claim 1 , further comprising:\n a cartridge for storing liquid and including a chamber which is open to the atmosphere; a supply route via which the cartridge is fluidly connected to the intermediate tank; and a replenishing pump on the supply route outside of the circulation route, wherein the controlling unit is configured to drive the replenishing pump to:\n send liquid to the intermediate tank when a liquid level of the intermediate tank is lower than a first predetermined level, and \n stop sending liquid to the intermediate tank when the liquid level of the intermediate tank is higher than a second predetermined level.
