Abstract:
1. A liquid ejecting apparatus comprising: unit ejection portions that includes a pressure chamber filled with liquid, nozzles which communicate with the pressure chamber, and a pressure generating element that varies the pressure within the pressure chamber, and ejects liquid within the pressure chamber from nozzle according to fluctuations of the pressure within the pressure chamber; a minute vibration control unit that controls the unit ejection portions so that minute vibrations having variable intensity are applied to the pressure chamber, wherein the minute vibrations do not cause the liquid in the pressure chambers to be ejected; and a flushing control unit that causes the respective unit ejection portions to execute a flushing operation so that an ejection quantity of liquid by the flushing operation of the pressure chamber, to which the minute vibrations of a first intensity is given, exceeds an ejection quantity of liquid by the flushing operation of the pressure chamber to which the minute vibration of a second intensity lower than the first intensity is given.
