Abstract
A liquid ejecting apparatus includes a liquid chamber in communication with a nozzle, a volume changing unit configured to change a volume of the liquid chamber, an inflow passage through which the liquid flows into the liquid chamber, an outflow passage through which the liquid flows out of the liquid chamber, a passage resistance changing unit configured to change a passage resistance of the outflow passage, and a controller configured to control the volume changing unit to reduce the volume of the liquid chamber so as to cause the liquid to be ejected through the nozzle. In filling the liquid chamber with the liquid for ejection of the liquid through the nozzle, the controller controls the passage resistance changing unit to change the passage resistance of the outflow passage to an increased passage resistance and controls the volume changing unit to increase the volume of the liquid chamber.
