ABSTRACT:
An ink-jet head protection assembly of the present invention comprises an ink-jet head, a head cap that protects the ink-jet head and a support member supporting the head cap so that the head cap contacts an ejection face of the ink-jet head. In the head cap, a surface confronting the ejection face of the ink-jet head is formed with a protrusion contacting the ejection face. A contact surface of the protrusion to the ejection face surrounds, in plan view, an area in which ejection ports are formed. Gas is filled in a closed space defined by a surface of the head cap, the protrusion and the ejection face.
