Abstract
A liquid ejecting apparatus includes a liquid ejection head, a supply tank, a recovery tank, a supply flow path, a recovery flow path, a pressurizing mechanism pressurizing the inside of the supply tank, and a depressurizing mechanism depressurizing the inside of the recovery tank. A filling period, in which a filling process is performed to fill, with the liquid, a nozzle, the supply flow path, and the recovery flow path, includes a period that is after a meniscus is formed in the nozzle and before the liquid reaches the recovery flow path. In the period, the pressurizing and the depressurizing mechanisms are driven; and in the period, Pt_out>−|Pm| is satisfied, where Pm indicates a pressure at which the meniscus is broken and Pt_out indicates a pressure in the recovery tank.
