Abstract:
1. A liquid ejection apparatus comprising: a head having an ejection face on which a plurality of ejection openings through which liquid is ejected are formed; a wiper which wipes the ejection face; a supplier which supplies liquid to the head so that liquid is ejected from the ejection openings; a first movement mechanism which moves at least either one of the wiper and the head in a first direction which is perpendicular to the ejection face, so as to make the wiper and the head overlap each other with respect to the first direction; a second movement mechanism which moves at least either one of the wiper and the head, so as to make the wiper move along the ejection face while being in contact with the ejection face; and a controller which controls the supplier to make liquid ejected from the ejection openings, wherein: the controller controls the first movement mechanism to make at least either one of the wiper and the head move in the first direction, and thereafter controls the second movement mechanism to make the wiper perform a first wiping, in the first wiping, while liquid is ejected from the ejection openings, the wiper moves along the ejection face while being in contact with the ejection face; the controller controls the second movement mechanism so as to make the wiper further perform a second wiping after the first wiping; in the second wiping, the wiper moves along the ejection face while being in contact with the ejection face, after liquid is ejected from the ejection openings and while no liquid is being ejected from the ejection openings; and the controller controls the first movement mechanism in such a manner that an amount by which the wiper and the head overlap each other with respect to the first direction is larger before the first wiping than before the second wiping, when the wiper is not contact with the ejection face before the movement by means of the second movement mechanism.
