Abstract
A liquid discharge apparatus includes: a first discharge section that has a first piezoelectric element and discharges liquid by driving the first piezoelectric element with a driving signal; a driving signal generation section that generates the driving signal; a first selection section that performs a selection operation of selecting whether or not to apply each voltage of a plurality of driving waveforms included in the driving signal to the first piezoelectric element, based on a print data signal; a residual vibration detection section that detects residual vibration of the first discharge section after a voltage of a first driving waveform among the plurality of driving waveforms is applied to the first piezoelectric element; and a control section that generates the print data signal, in which the control section stops the driving signal generation section when causing the residual vibration detection section to detect the residual vibration.
