Abstract
A liquid ejecting apparatus includes a nozzle for ejecting liquid, a pressure chamber communicating with the nozzle, a first individual flow path communicating with the pressure chamber, a second individual flow path communicating with the pressure chamber, a pressure generating unit changing a pressure of the liquid in the pressure chamber, and a control unit for driving the pressure generating unit. In the liquid ejecting apparatus, the liquid is supplied into the pressure chamber via one of the first individual flow path and the second individual flow path, and at least a part of the liquid supplied into the pressure chamber is discharged via the other. The control unit introduces air into the pressure chamber via the nozzle by driving the pressure generating unit, during a period in which the liquid is not ejected from the nozzle.
