Liquid droplet discharge device, liquid droplet discharge method, and non-transitory storage medium storing program

摘要

A liquid droplet discharge device includes pressure chambers in communication with nozzles, wherein the pressure chambers are for storing ink; an oscillation plate that is disposed over the pressure chambers, so that an elastic wall of each of the pressure chambers is formed; pressure generating elements that are disposed to face the pressure chambers through the oscillation plate; a drive waveform generator for generating, for each of the nozzles, a drive waveform by using drive waveform data that indicates a shape of the drive waveform for driving the corresponding pressure generating element; a residual oscillation detector for detecting residual oscillation that is generated in each of the pressure chambers after driving the pressure generating elements; and a controller for correcting, during printing, the drive waveform data for each of the nozzles, based on a detection result by the residual oscillation detector.
