Abstract
A liquid droplet ejecting device that includes multiple pressure chambers communicating with multiple nozzles, to contain liquid; a vibration plate, to constitute elastic walls of the pressure chambers, disposed extending along the pressure chambers; multiple pressure generating elements disposed facing the multiple chambers respectively via the vibration plate; a drive waveform generator to generate drive waveform data that indicates a shape of a drive waveform for driving the multiple pressure generating elements; a residual vibration detector to detect a residual vibration waveform occurring within the pressure chamber after the pressure generating elements are driven; and a controller to determine the necessity of liquid-state recovery ejection for discharging thickened liquid, based on the detected residual vibration, and to causes the liquid-state recovery ejection to be performed upon determining that liquid-state recovery ejection is needed.
