1. A liquid ejecting apparatus, comprising:
- a liquid supply path which is designed to supply a liquid from a liquid supply source to a liquid ejecting unit which ejects the liquid from a nozzle;
a pressure-regulating mechanism provided in the liquid supply path, the pressure-regulating mechanism includinga liquid inflow part into which the liquid supplied from the liquid supply source flows;
a liquid accommodation part which is designed to accommodate the liquid;
a communication path through which the liquid inflow part and the liquid accommodation part communicate, andan on-off valve which enters an open state in which the liquid inflow part and the liquid accommodation part communicate from a closed state in which the liquid inflow part and the liquid accommodation part in the communication path do not communicate; and
a pressurizing mechanism which is designed to pressurize the liquid supplied to the pressure-regulating mechanism,wherein the liquid ejecting unit includes an actuator which is driven when ejecting the liquid from the nozzle, andthe actuator of the liquid ejecting unit is driven by a controller in a process which puts the on-off valve in the closed state from the open state.

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.

11. A maintenance method of a liquid ejecting apparatus comprising the steps of:
-
providing the liquid ejecting apparatus having; a liquid ejecting unit which ejects a liquid from a nozzle, the liquid ejecting unit including an actuator which is driven when ejecting the liquid from the nozzle; a liquid supply path which is designed to supply the liquid from a liquid supply source to the liquid ejecting unit; a pressure-regulating mechanism provided in the liquid supply path, the pressure-regulating mechanism including a liquid inflow part into which the liquid supplied from the liquid supply source flows; a liquid accommodation part which is designed to accommodate the liquid; a communication path through which the liquid inflow part and the liquid accommodation part communicate, and an on-off valve which enters an open state in which the liquid inflow part and the liquid accommodation part communicate from a closed state in which the liquid inflow part and the liquid accommodation part in the communication path do not communicate; and a pressurizing mechanism which is designed to pressurize the liquid supplied to the pressure-regulating mechanism; putting the on-off valve in the open state in a state in which the liquid is pressurized by the pressurizing mechanism, and driving the actuator of the liquid ejecting unit in a process which puts the on-off valve in the closed state from the open state. - View Dependent Claims (12)
