Patent ID: 8905506

Claim:
A liquid ejecting apparatus comprising: a liquid ejecting head that includes a nozzle group in which a plurality of nozzles are arranged and a pressure generation unit causing a change in pressure inside a pressure chamber communicating with the nozzle and that causes the pressure generation unit to eject a liquid from the nozzles; a driving waveform generation unit that generates a driving waveform used to drive the pressure generation unit; a control unit that controls ejection of the liquid by the liquid ejecting head; and a counting unit that counts a cumulative number of times the driving waveform is applied, wherein the driving waveform generation unit generates a non-ejection driving waveform, wherein a driving parameter of the non-ejection driving waveform includes at least one of a driving voltage, a potential change ratio per unit time, a hold time in which a potential is constantly held, and the number of times a pulse is continuously applied, and wherein the control unit drives the pressure generation unit using the non-ejection driving waveform set in accordance with the cumulative number of times the driving waveform is applied.
