LIQUID DISCHARGE DEVICE AND LIQUID DISCHARGE METHOD

To enable a head to discharge liquid stably.SOLUTION: A liquid discharge device according to one embodiment of the present invention comprises: a head that discharges liquid; an output part that outputs, to the head, driving waveform data including data on discharging/driving waveforms for discharging the liquid and data on vibrating/driving waveforms for vibrating the liquid in the head without discharging the liquid; and a changing part that makes second frequencies at which the vibrating/driving waveforms are outputted to the head different from first frequencies, in accordance with the first frequencies at which the driving waveforms are outputted to the head.SELECTED DRAWING: Figure 8 【課題】ヘッドからの液体吐出を安定化させること。【解決手段】本発明の一態様に係る液体吐出装置は、液体を吐出するヘッドと、前記液体を吐出させる吐出駆動波形のデータと前記液体を吐出させずに前記ヘッド内の前記液体を振動させる振動駆動波形のデータとを含む駆動波形のデータを前記ヘッドに出力する出力部と、前記ヘッドに前記駆動波形が出力される第１周波数に応じて、前記ヘッドに前記振動駆動波形が出力される第２周波数を前記第１周波数に対して異ならせる変更部と、を有する。【選択図】図８
