Patent ID: 7878619

Claim:
A maintenance method of a fluid ejecting apparatus having an ejection head that is movable in a predetermined direction and ejects fluid onto a medium; a cap member that faces an ejection region of the ejection head, a portion facing the ejection region being tiltable with respect to the ejection head, and that comes into contact with an ejection surface of the ejection head for ejecting fluid so as to cover the ejection surface; and a potential difference detection unit that detects a potential difference between the cap member and the ejection head, the maintenance method comprising: when a capped state, in which a space including the election surface is covered by the cap member, is to be terminated, terminating the capped state from a part of the cap member by tilting the facing portion of the cap member with respect to the ejection head; after termination of the capped state, ejecting fluid from a first portion of the ejection region toward a predetermined region of the facing portion and detecting the potential difference resulting from the ejection of the fluid from the ejection head; after ejection of the fluid from the first portion, moving the ejection head in the predetermined direction and positioning a second portion of the ejection region provided behind the first portion of the ejection region in the predetermined direction at a position overlapping the predetermined region in a plan view; after movement of the ejection head, ejecting fluid from the second portion toward the predetermined region; and detecting the potential difference resulting from the ejection of the fluid from the ejection head.
