发明名称 Pump wetting in a liquid ejecting apparatus
摘要 A liquid ejecting apparatus includes: a head member having a nozzle and a liquid-ejecting unit; a main controlling part that drives the liquid-ejecting unit based on ejecting data; a capping member relatively movable between a position away from the head member and a position in contact with the head member; a suction way communicated with an inside of the capping member; and a built-in slide-rotator type of positive displacement pump provided in the suction way. Astate-quantity recognizing part recognizes a state quantity related to a dry state in an inside of the positive displacement pump. A judging part judges whether the inside of the positive displacement pump is dry, by comparing the state quantity with a standard state quantity. A preliminary-operation carrying-out part carries out a preliminary operation for wetting the inside of the positive displacement pump, when the inside of the positive displacement pump is dry. <IMAGE>
