Method for preserving a liquid-ejection head, and liquid-ejection apparatus |
摘要 |
A method for preserving a liquid-ejection head is disclosed. The method uses the liquid-ejection head having a first liquid-flowing passage that receives a supply of a first liquid and communicates with an ejection port; a second liquid-flowing passage that receives a supply of a second liquid that differs from the first liquid; a bubble generation area formed on the second liquid-flowing passage for heating the second liquid to generate a bubble in said second liquid; and a movable member positioned between the bubble generation area, having a free end on an ejection port's side of the first liquid-flowing passage and a supporting end on other side of the first liquid-flowing passage, where the free end of the movable member is displaced toward the first liquid-flowing passage by a pressure caused by a generation of the bubble when said second liquid is heated. The method includes a step of performing a replacement of one of the fist liquid and the second liquid with the other at least at a periphery of the ejection port or a periphery of the movable member. Thus the liquid-ejection head is able to perform an excellent recording whether it has not been used for a long time. <IMAGE> |
