Abstract
A fluid ejecting apparatus includes a drive element that performs a driving operation when a drive waveform is applied thereto and causes a nozzle to eject fluid. A drive signal generating unit generates a first drive signal having a first drive waveform at a front section of a predetermined period and a second drive waveform at a rear section thereof. A second drive signal has a third drive waveform at a front section of the predetermined period and a fourth drive waveform at a rear section thereof. A control unit applies the first drive waveform to the drive element, which then performs a first operation, applies the fourth drive waveform to the drive element, which then performs a second operation, and applies the second drive waveform to the drive element after applying the third drive waveform thereto, so that the drive element performs a third operation.
