Abstract:
1. A liquid ejection apparatus, comprising: a liquid ejection head having an ejection face that has a plurality of ejection openings through which the liquid ejection head ejects liquid, an ejection space being defined so as to face the ejection face; a sealing mechanism configured to selectively establish (i) a sealing state in which the sealing mechanism seals the ejection space from an outside space and (ii) an unsealing state in which the sealing mechanism does not seal the ejection space from the outside space; a first opening and a second opening formed respectively at positions interposing at least a part of the ejection face therebetween in one direction, the first opening and the second opening each being for supplying air into the ejection space therethrough; a generating portion configured to generate humid air; a supply portion configured to supply the humid air generated by the generating portion into the ejection space in the sealing state via one of the first opening and the second opening; and a controller configured to control the supply portion such that a first period in which the humid air is supplied via the first opening and is not supplied via the second opening, and a second period in which the humid air is not supplied via the first opening and is supplied via the second opening do not overlap each other in a current humid-air supply processing.
