Abstract
According to one embodiment, a liquid ejection device includes a nozzle plate, an actuator, a liquid supply unit, a waveform generation circuit, a waveform allocation circuit, and a drive signal output circuit. A plurality of nozzles for ejecting liquid is arranged in the nozzle plate. The actuator is provided in each of the nozzles. The waveform generation circuit generates plural kinds of drive waveforms with different generation start timings. The waveform allocation circuit can set the drive waveform among plural kinds of drive waveforms and the actuator of the nozzle to be allocated. The drive signal output circuit drives the actuator with the allocated drive waveform.
