Abstract
When a nozzle abnormality detecting mechanism detects an abnormality of the nozzle, in the maintenance process of causing the drive waveform to be applied plural times to the actuator corresponding to the nozzle that the detecting mechanism detects as being abnormal, and thereby causing the ejecting operation to be performed, at least a first-time drive waveform applied to the actuator is a flushing pulse which causes a meniscus in the nozzle not to be positively attracted from an initial position to the pressure chamber, but causes the meniscus to be extruded to the ejection side and thereby causes the liquid to be ejected from the nozzle.
