Abstract
A method for driving a liquid ejecting apparatus includes storing initial information on a residual vibration that occurs in the pressure chamber when the inspection signal is supplied at a first timing to the pressure generating element, storing determination target information on a residual vibration that occurs in the pressure chamber when the inspection signal is supplied at a second timing later than the first timing to the pressure generating element, and determining a property change in the pressure generating element based on the initial information, the determination target information, and correspondence information on, for each viscosity of the liquid in the pressure chamber, a correspondence between an amplitude of the residual vibration and a displacement amount of the pressure generating element.
