Abstract
A liquid ejecting apparatus includes: a liquid ejecting section in which a nozzle capable of ejecting liquid is provided; a supply flow path that supplies the liquid to the nozzle; a pressurizing mechanism that discharges the liquid from the nozzle by pressurizing the liquid inside the supply flow path; and a pressure reducing mechanism that discharges the liquid from the nozzle by reducing a pressure of a space communicating with a side opposite to a side of the supply flow path of the nozzle. In a maintenance operation discharging the liquid from the nozzle by driving at least one of the pressurizing mechanism and the pressure reducing mechanism, the last discharging operation of the maintenance operation is performed by driving the pressurizing mechanism from a state where the negative pressure is caused to act on the inside of the nozzle by driving the pressure reducing mechanism.
