Patent ID: 8322815

Claim:
A method of cleaning a fluid ejecting apparatus including an ejection head including a plurality of ejection nozzles for ejecting a fluid to a target and a common fluid chamber from which the fluid is supplied to the ejection nozzles, the method comprising: performing a preliminary discharge operation for discharging the fluid from the ejection nozzles before the fluid is ejected to the target; detecting a fluid ejection state of the ejection nozzles after the preliminary discharge operation is finished; determining a processing parameter at the time of cleaning of the ejection head on the basis of the detected result; and performing cleaning with respect to the ejection heads on the basis of the processing parameter, wherein, in the performing of the preliminary discharge operation, the fluid of the amount corresponding to at least the volume of the common fluid chamber is ejected, wherein the preliminary discharge operation is performed without detecting the fluid ejection state of the ejection nozzles and wherein the preliminary discharge operation is performed when a predetermined time from a precedent preliminary discharge operation is elapsed.
