Abstract:
A liquid discharge device includes a liquid discharge head including a plurality of liquid chambers respectively communicating with a plurality of nozzles and circulating liquid therethrough. Each liquid chamber is provided with a pressure generator for discharging the liquid from a corresponding nozzle. The liquid discharge device further includes a waveform data memory to store drive waveform data including discharge drive waveform data for discharging the liquid according to image data and micro-vibration drive waveform data for causing a micro vibration of a meniscus of the liquid discharge head. The liquid discharge device further includes circuitry configured to generate a drive waveform based on the drive waveform data; apply, to the pressure generator, a discharge drive waveform based on the discharge drive waveform data, in a printing area; and apply, to the pressure generator, a micro-vibration drive waveform based on the micro-vibration drive waveform data, in a non-print area.
