Abstract
A liquid ejecting apparatus includes an ejection unit that ejects a liquid by a piezoelectric element being driven, a drive signal generation unit that generates a drive signal for driving the piezoelectric element, a residual vibration detection unit that detects a residual vibration of the ejection unit after the drive signal is applied to the piezoelectric element, and an inspection control signal generation unit that generates an inspection control signal for instructing start of detection of the residual vibration by the residual vibration detection unit. The inspection control signal when a temperature of the ejection unit is a first temperature differs from the inspection control signal when the temperature of the ejection unit is a second temperature lower than the first temperature.
