Abstract
A technique allows satisfactorily cleaning ejection heads with a cleaning liquid while protecting ink meniscus in nozzles. A printer includes an ejection head, a cleaning-liquid block, and a receptacle. The ejection head has an ink ejecting plane that includes nozzles as openings and ejects ink from the nozzles. The cleaning block has a head opposing plane that includes an ejection hole as an opening. The cleaning block ejects a cleaning liquid in an inclination direction inclined relative to the ink ejecting plane. The receptacle is located below the cleaning block and receives the cleaning liquid ejected from the ejection hole.
Claims9
A printer comprising:
- at least one ejection head that has a bottom surface comprising:
- an ink ejecting plane, which includes a nozzle as an opening and is configured to eject ink from the nozzle;
- and
- a raised plane that extends below the ink ejecting plane;
- a cleaning-liquid ejector that has a head opposing plane including an ejection hole, the ejection hole ejecting cleaning liquid in a direction inclined relative to the ink ejecting plane, wherein the cleaning liquid cleans the bottom surface of the ejection head;
- a suction part that sucks a liquid through a suction hole, wherein the suction hole is open in the head opposing plane;
- and
- a receptacle that is located below the cleaning-liquid ejector and that receives the cleaning liquid ejected from the ejection hole,
- wherein the head opposing plane of the cleaning-liquid ejector is located below and faces the ink ejecting plane when the cleaning liquid is ejected, and
- wherein the suction hole faces only the raised plane from below when the cleaning liquid is ejected.
