Abstract:
A liquid ejecting apparatus includes a liquid inflow unit provided in the liquid supply path which supplies a liquid to a liquid ejecting unit and into which the liquid flows, a liquid accommodation unit having a diaphragm section, a communication path through which the liquid inflow part and the liquid accommodation part communicate, and a pressure-regulating mechanism having an on-off valve which opens and closes the communication path in response to displacement of the diaphragm portion, and a pressing mechanism which puts the on-off valve in an open state regardless of the pressure in the liquid inflow unit by pressing the diaphragm portion.

Claim (Index 8):
A method of controlling a liquid pressure in a liquid ejecting apparatus, the method comprising the steps of:\n providing the liquid ejecting apparatus having:\n a liquid ejecting head which ejects a liquid from a nozzle; \n a liquid supply path which is designed to supply the liquid to the liquid ejecting head; \n a pressure-regulating mechanism which is designed to regulate a pressure of the liquid supplied to the liquid ejecting head, the pressure-regulating mechanism including: \n an on-off valve which is provided in the liquid supply path and is configured to switch to an open state in which an upstream-side liquid supply path and a downstream-side liquid supply path communicate and switch to a closed state in which the upstream-side liquid supply path and the downstream-side liquid supply path do not communicate in a case where an upstream side of the on-off valve in the liquid supply path is the upstream-side liquid supply path and a downstream side of the on-off valve in the liquid supply path is the downstream-side liquid supply path; and \n a valve opening/closing mechanism which is designed to switch the on-off valve to the open state and the closed state; a pressurizing mechanism which is designed to pressurize the liquid in the upstream-side liquid supply path; a liquid discharge path which is designed to discharge the liquid from the liquid ejecting head, the liquid discharge path forming a liquid circulation path in cooperation with the liquid ejecting head and the liquid supply path; and driving of the opening/closing mechanism in a state where the liquid in the upstream-side liquid supply path is in a pressurized state by driving the pressurizing mechanism, and a pressure of the liquid supplied to the liquid ejecting head is regulated.
