Abstract:
1. A manufacturing method of a liquid ejecting apparatus which includes, a piezoelectric element that has a piezoelectric layer made of non-lead complex oxide and an electrode provided at the piezoelectric layer and a drive section that supplies a drive waveform driving the piezoelectric element to the piezoelectric element, the method comprising: setting, as a drive voltage range for the drive waveform, a predetermined voltage range in which a displacement associated with the liquid ejecting apparatus is greater than a predetermined ratio, wherein setting the predetermined voltage range includes determining the predetermined voltage range from a relationship between first and second voltages, having a voltage difference, and the displacement by: changing a reference waveform from the first voltage to the second voltage, changing the first voltage and the second voltage while maintaining the same voltage difference between the first voltage and the second voltage, changing the reference waveform from the changed first voltage to the changed second voltage, and determining the predetermined range according to the relationship between the first and second voltages and the displacement; and setting the drive waveform which the drive section supplies to the piezoelectric element as a drive waveform defined in a minimum voltage and a maximum voltage defined within a drive piezoelectric range.
