Abstract:
An ejection apparatus includes an ejection head, and a recessed portion, a wiper, an installation unit, and a moving unit configured to move the blade and the ejection head relative to each other, wherein the wiper performs a wiping operation for wiping the ejection head to wipe the ejection port after wiping the recessed portion, and wherein in the wiping operation, a first wiping operation is performed in a state where the ejection port surface and the installation unit on which the wiper is installed are at a first distance in a direction perpendicular to the ejection port surface, and a second wiping operation is performed in a state where the ejection port surface and the installation unit on which the wiper is installed are at a second distance in the direction perpendicular to the ejection port surface, the second distance being larger than the first distance.
