METHOD OF DRIVING LIQUID EJECTING APPARATUS

Abstract: a method of driving a liquid ejecting apparatus including a piezoelectric element, and a pressure chamber. the method includes: generating a plurality of pairs of first drive signals and second drive signals, the first drive signals include electrical potential-changing elements that change in electrical potential, and the second drive signals that include electrical potential-maintained elements that maintain fixed electrical potentials, and detecting, as a plurality of residual vibration signals for the plurality of pairs, variations in electromotive force of the piezoelectric element according to variations in residual pressure that is applied to liquid in the pressure chamber after every supplying the electrical potential-changing element and the electrical potential-maintained element to the piezoelectric element for the plurality of the pairs, and identifying a first deformation property of the piezoelectric element based on the plurality of residual vibration signals for the plurality of pairs.
