According to one embodiment, a liquid discharge apparatus includes a nozzle plate configured such that a plurality of nozzles are arranged, a liquid supply unit, an actuator, a driving circuit, and a low impedance circuit. The nozzles arranged in the nozzle plate discharge a liquid. The liquid supply unit communicates with the nozzles. The actuator is provided for each nozzle in the nozzle plate. The actuator includes a piezoelectric element. The driving circuit supplies a driving signal to the piezoelectric element of the actuator and drives the actuator to discharge a liquid from the nozzles. The low impedance circuit is connected to the piezoelectric element of the actuator while stress is applied to the nozzle plate due to external factors.
A liquid discharge apparatus, comprising:
An ink jet printer, comprising:
A method of operating a liquid discharge apparatus comprising a nozzle plate comprising a plurality of nozzles for discharging a liquid are arranged, a liquid supply unit which communicates with the nozzles, a plurality of actuators each of which is provided for a respective nozzle of the plurality of nozzles in the nozzle plate, each actuator comprising a piezoelectric element, the method comprising:
