Abstract:
A liquid ejecting apparatus includes a piezoelectric element, a nozzle that ejects a liquid in association with the driving of the piezoelectric element, a driving signal generation unit that generates a driving signal for driving a plurality of the piezoelectric elements, and a residual vibration detection unit that detects residual vibration generated by the driving of the piezoelectric element. The driving signal includes an ejection pulse for ejecting a liquid, a first vibration damping pulse that suppresses residual vibration generated by the ejection pulse, a second vibration damping pulse which is a pulse different from the first vibration damping pulse and suppresses residual vibration generated by the ejection pulse, and an inspection pulse for detecting the residual vibration signal.
