Abstract
A fluid ejection device configured to eject fluid from an ejection port includes a driving element that pressurizes the fluid and causes it to be ejected from the ejection port by being driven according to a voltage applied thereto. A driving voltage waveform selecting unit selects a driving voltage waveform to be applied to the driving element from among a plurality of types of the stored driving voltage waveforms. Power sources set the voltage to be outputted. A power source voltage determining unit determines voltages to be set to the power sources on the basis of the selected driving voltage waveform. A driving voltage waveform applying unit applies the selected driving voltage waveform to the driving element by setting the determined voltages to the power sources and connecting the power sources to the driving element while switching the same.
