Abstract:
In a filling operation of filling liquid in a liquid supply flow path which includes a filter having holes by causing a pressure on a downstream side in the liquid supply flow path to be lower than a pressure on an upstream side, and a maximum pressure difference which occurs between an upstream side of the filter and a downstream side of the filter is larger than a pressure difference for destroying a gas-liquid interface formed in the hole in a case where the upstream side of the filter is the liquid, and the downstream side of the filter is gas, and is smaller than a pressure difference for destroying the gas-liquid interface formed in the hole, in a case where the upstream side of the filter is the gas, and the downstream side of the filter is the liquid.

Claim (Index 1):
A liquid ejecting apparatus comprising:\n a liquid ejecting unit which includes a nozzle opening which ejects liquid; a liquid supply flow path through which the liquid can be supplied to the nozzle opening of the liquid ejecting unit from a liquid supply source; and a filter portion which includes a filter which is provided with a plurality of holes through which a fluid can pass, the filter collecting foreign substances, and the filter portion configuring a part of the liquid supply flow path, wherein, in the liquid supply flow path, in a case in which the liquid supply source side is set to an upstream side, and the nozzle opening side is set to a downstream side, a maximum pressure difference which occurs between an upstream side filter chamber as an upstream side of the filter and a downstream side filter chamber as a downstream side of the filter, in the filter portion, is larger than a pressure difference for destroying a gas-liquid interface which is formed in the hole in a case in which the upstream side of the filter is the liquid, and the downstream side of the filter is gas, and is smaller than a pressure difference for destroying the gas-liquid interface which is formed in the hole in a case in which the upstream side of the filter is the gas, and the downstream side of the filter is the liquid, in a filling operation in which the liquid supply flow path in a state of not being filled with the liquid is filled with the liquid in the liquid supply source, by causing a pressure to be operated so as to make a pressure on the downstream side lower than a pressure on the upstream side.
