Liquid discharge apparatus and control method of liquid discharge apparatus
Abstract:
A liquid discharge apparatus includes a piezoelectric element in which a drive signal is applied and which is displaced to eject a liquid; a zeroth wire of a zeroth potential; a first wire of a first potential that is higher than the zeroth potential; a second wire of a second potential that is higher than the first potential; and a connection path selecting section that electrically connects one end of the piezoelectric element to the zeroth wire, the first wire, or the second wire in response to a voltage of a source drive signal that controls the voltage of the drive signal and a hold voltage of the piezoelectric element. Here, a first potential difference from the zeroth potential to the first potential is different from a second potential difference from the first potential to the second potential.
