FLUID EJECTION APPARATUS
摘要:
A fluid ejection apparatus that ejects fluid from an ejection nozzle in an ejection head includes a fluid receiver that has a concave portion for accommodating the ejected fluid and defines a closed space around the ejection nozzle when the concave portion contacts the ejection head. Suction pumps suck the fluid in the concave portion through suction ports in the concave portion. A fluid suction unit sucks the fluid in the ejection head through the ejection nozzle by operating the suction pumps such that the concave portion contacts the ejection head. An air suction unit sucks the air and the fluid in the concave portion of the fluid receiver after completion of suction of the fluid in the ejection head, by allowing at least one suction pump to reverse the air flow in collaboration with the operation of at least one other suction pump.
