Patent ID: 8353584

Claim:
A liquid discharging apparatus comprising: a liquid container configured to contain a liquid; an energy generating element used to discharge the liquid from a discharge port; a supply flow path configured to supply the liquid from the liquid container to the energy generating element; a negative-pressure maintenance unit provided in the supply flow path; a collecting flow path configured to collect the liquid from the energy generating element into the liquid container; a pump provided in the collecting flow path; and a control unit configured to control the negative-pressure maintenance unit and the pump, the control unit adjusting Pu and Pd so that a condition “Pu>Pd, Pn>−Pd” is satisfied, where Pu denotes a pressure in a flow path on the upstream side of the energy generating element, Pd denotes a pressure in the flow path on the downstream side of the energy generating element, and Pn denotes a pressure equivalent to a capillary force for refilling the flow path with the liquid when the liquid has been discharged from the discharge port.
