Claim Text:
1. A liquid ejecting apparatus, comprising: a liquid ejecting head that includes pressure chambers communicating with nozzles, and actuators causing a pressure variation of liquid in the pressure chamber to occur, the liquid ejecting head being able to eject the liquid from the nozzle through an action of the actuator; and a detecting mechanism that detects an abnormality of the nozzle in liquid ejection, wherein the liquid ejecting apparatus drives the actuator with a drive waveform to perform a maintenance process, wherein 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 maintenance drive waveform 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, and wherein a flushing pulse which causes a meniscus in the nozzle to be positively attracted from an initial position to the pressure chamber is to be applied to the actuator after the maintenance drive waveform.
