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 9):
A maintenance method for a liquid ejecting apparatus which 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, 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, and a pressure adjustment mechanism that adjusts a pressure in the liquid ejecting unit by opening and closing the liquid supply flow path between the pump chamber and the liquid ejecting unit, the method comprising:\n causing the pump mechanism to perform the suction driving operation until the amount of liquid accommodated in the pump chamber reaches a set value; causing the pressure adjustment mechanism to open the liquid supply flow path after the suction driving operation; and causing the pump mechanism to perform the discharge driving operation after the liquid supply flow path is opened such that the liquid is discharged from the nozzle.
