Abstract

An actuator drive circuit of a liquid discharge apparatus includes a discharge waveform generating circuit, a sleep waveform generating circuit, and a wake waveform generating circuit. The discharge waveform generating circuit is configured to generate a plurality of drive waveforms to be applied to actuators of the liquid discharge apparatus for liquid discharge. The drive waveforms correspond to gradation values of gradation scale data. The sleep waveform generating circuit is configured to generate a sleep waveform to be applied to the actuators. The sleep waveform causes a voltage of the actuators to transition to a first voltage without liquid discharge. The wake waveform generating circuit is configured to generate a wake waveform to be applied to the actuators. The wake waveform causes the voltage of the actuators to transition to a second voltage higher than the first voltage without liquid discharge.
