Abstract
A liquid ejecting apparatus includes a correction section maintains a predetermined voltage range in which a displacement is greater than a predetermined ratio as a drive voltage range from a relationship between each voltage and the displacement when a reference waveform having a process that changes the voltage from a first voltage to a second voltage having a voltage difference and a process that changes the voltage from the second voltage to the first voltage is supplied by making the voltage difference between the first voltage and the second voltage constant and changing the first voltage and the second voltage, and wherein the correction section changes the drive waveform into a drive waveform having a minimum voltage and a maximum voltage defined within the drive voltage range.
