Abstract:
1. A liquid ejecting apparatus comprising: a liquid ejecting head that includes a nozzle array formed of a plurality of nozzles, a pressure chamber array formed of a plurality of pressure chambers provided along the nozzle array, and a plurality of piezoelectric elements which generate a pressure variation of liquid in each pressure chamber; and a drive potential generator that generates a drive potential which drives the piezoelectric element, wherein the pressure chamber array includes one or more dummy pressure chambers in which ejection of the liquid is not performed, and the one or more dummy pressure chambers each include one of the piezoelectric elements, and wherein the drive potential generator continues to apply the drive potential to the piezoelectric element corresponding to the dummy pressure chamber, while the ejection of the liquid from a nozzle of at least a pressure chamber adjacent to the dummy pressure chamber is performed, wherein the drive potential includes a first waveform that is applied to the pressure chamber adjacent to the dummy pressure chamber when the liquid is ejected and a second waveform different from the first waveform that is applied to the dummy pressure chamber when the liquid is ejected from the pressure chamber adjacent to the dummy pressure chamber.
