Abstract
A method of controlling a liquid ejecting apparatus that includes a liquid ejecting head having nozzles configured to eject a liquid, pressure chambers communicating with the nozzles, and drive elements configured to change the volume in the pressure chambers, and a drive-waveform generating circuit configured to generate a drive waveform for driving the drive elements to vibrate the liquid in the nozzles is provided. The method includes detecting a power-off operation for issuing an instruction for turning off an electric power of the liquid ejecting apparatus and vibrating the liquid by driving piezoelectric elements by the drive waveform in response to detecting the power-off operation by the detecting.
