Abstract:
1. A liquid ejecting apparatus, comprising: a plurality of nozzles that eject a liquid; a sensor that detects a defective nozzle in which defective ejection occurs when the liquid is to be ejected; a recovery mechanism that recovers the defective nozzle to its normal state so as to enable the liquid to be normally ejected from the defective nozzle; a control unit that, when a defective nozzle is detected, compares a first method, in which the liquid is ejected after the defective nozzle is recovered to its normal state by the recovery mechanism, with a second method, in which the liquid is ejected without using the defective nozzle, while the defective nozzle is not recovered to its normal state, and controls the liquid to be ejected by using one of the first or the second method having a shorter processing time.
