Title:
液体吐出装置、液体吐出ユニット
Document Type and Number:
Japanese Patent JP7081239
Kind Code:
B2
Abstract:
A liquid discharge device includes a nozzle plate including nozzles to discharge liquid; individual liquid chambers communicating with nozzles; a common liquid chamber to supply the liquid to the individual liquid chambers; a circulation channel; a common circulation chamber; a pressure generator to apply pressure to the liquid; and circuitry to apply, to the pressure generator, a predetermined drive waveform in which an electric potential is changed, from a first potential to apply an initial pressure to the liquid, to a second potential, and the second potential is kept to a predetermined timing for liquid discharging. At the predetermined timing, a discharge speed difference, caused when the initial pressure is changed in a case where the predetermined drive waveform is applied with the initial pressure applied to the liquid, is a local minimum. The initial pressure is applied to the liquid in a state without the predetermined drive waveform.
