Abstract:
A liquid ejecting apparatus includes a liquid ejecting unit provided with a nozzle from which liquid is ejected, a liquid supply flow path connected to a liquid supply source and the liquid ejecting unit, and a pump mechanism that includes a pump chamber provided in the liquid supply flow path and that repeats a suction driving operation and a discharge driving operation such that the liquid flows toward the liquid ejecting unit from the liquid supply source. Before maintenance of the liquid ejecting unit is performed by discharging liquid from the nozzle, the pump mechanism performs the suction driving operation until the amount of liquid accommodated in the pump chamber reaches a set value, which is set in advance.

Claim (Index 4):
The liquid ejecting apparatus according to  claim 3 ,\n wherein the pressure adjustment mechanism includes\n a liquid inflow portion that is disposed in the liquid supply flow path, \n a liquid outflow portion that is disposed in the liquid supply flow path between the liquid inflow portion and the liquid ejecting unit, \n a diaphragm that constitutes a portion of a wall surface of the liquid outflow portion, and \n an on-off valve that opens and closes the liquid supply flow path between the liquid inflow portion and the liquid outflow portion, and \n wherein, the on-off valve opens the liquid supply flow path when a pressure applied to a first surface of the diaphragm is lower than a pressure applied to a second surface and a difference between the pressure applied to the first surface and the pressure applied to the second surface is equal to or greater than a predetermined value, the first surface being a surface of the diaphragm that is close to the inside of the liquid outflow portion and the second surface being a surface opposite to the first surface.
