Abstract
A liquid ejection apparatus includes an ejection head configured to include an ejection port surface in which ejection ports for ejecting liquid are arranged, a cap configured to be movable to a capping position where the ejection port surface is capped, and to an uncapped position where the ejection port surface is not capped, and a cleaning mechanism configured to be movable, independently of the cap, to a cleaning position where the ejection head is cleaned, and to a standby position where the ejection head is not cleaned. The cap at the uncapped position is positioned above the cleaning mechanism at the standby position.
Claims16
A liquid ejection apparatus comprising:
- a plurality of ejection heads, including a first ejection head and a second ejection head, configured to include ejection port surfaces in which ejection ports for ejecting liquid are arranged;
- a plurality of head holders, including a first head holder for the first ejection head and a second head holder for the second ejection head, each configured to move the ejection head between a recording position for recording by the ejection head and a retracted position above the recording position;
- a plurality of caps, including a first cap for the first ejection head and a second cap for the second ejection head, configured to be moved by a cap tray to a capping position where the respective ejection port surfaces are capped, and to an uncapped position where the respective ejection port surfaces are not capped;
- a plurality of first positioning portions provided on the cap tray and configured to position one side of each ejection head in a longitudinal direction of each ejection head at the capping position;
- a plurality of second positioning portions provided on the cap tray and configured to position another side of each ejection head in the longitudinal direction at the capping position;
- and
- a plurality of cleaning mechanisms configured to be moved by a cleaning tray, the cleaning tray being configured to move independently of the cap tray, to a cleaning position where the ejection heads are cleaned, and to a standby position where the ejection heads are not cleaned,
- wherein the cap tray at the uncapped position is positioned above the cleaning tray at the standby position, and
- wherein the first cap and the second cap are each arranged between the first positioning portion and the second positioning portion in the longitudinal direction.
