Abstract
A liquid ejecting apparatus includes a common liquid chamber communicating with nozzles, a filter partitioning the common liquid chamber into an upstream chamber and a downstream chamber, an inlet and an outlet for the upstream chamber, a liquid storage section, a supply flow path, and a recovery flow path. A beam portion is provided inside the downstream chamber. A pressurization discharge operation for discharging the liquid from the nozzles by pressurizing the supply flow path and a circulation operation for circulating the liquid in a circulation path including the liquid storage section, the supply flow path, the common liquid chamber, and the recovery flow path, are performed. In a process of filling the circulation path with the liquid, the circulation operation is performed after the pressurization discharge operation is performed.
