Abstract
A liquid ejecting apparatus includes a liquid ejecting head with a plurality of nozzles that eject a liquid to a medium; the liquid ejecting head has actuators (piezoelectric devices), each of which causes an ejection operation for ejecting the liquid from one of the nozzles and a protrusion operation for keeping the liquid protruded from a nozzle plane in which the nozzles are disposed. The liquid ejecting apparatus also includes a controller that identifies non-used nozzles from which not to eject the liquid to the medium to have the protrusion operation performed for the nozzles and also identifies nozzles from which to eject the liquid to have the ejection operation performed for the nozzles.
