Abstract:
A fluid ejection device that ejects fluid from an ejection port includes: a drive element that ejects fluid in accordance with a difference between voltages applied to a first terminal and a second terminal; a drive voltage waveform storing unit that stores a drive voltage waveform applied to the drive element; a plurality of power supplies each having a different voltage; and a drive voltage waveform applying unit that applies the drive voltage waveform to the drive element by switching among the plurality of power supplies connected to the first and second terminals of the drive element.
