Patent ID: 7645022

Claim:
A mobile device including: (a) an inkjet printhead; (b) a print media feed path for directing print media past the printhead in a feed direction during printing; (c) a capping mechanism including a capper moveable between a capping position and an uncapped position, the capping mechanism being biased to the capping position in which the capper is urged into a capping relationship with the printhead; and in the uncapped position, the capper is displaced away from the printhead against the bias such that the printhead is able to print onto the print media; (d) a locking mechanism including actuation arms, configured to hold the capper in the uncapped position in response to the actuation arms sliding against the media as the media is printed by the inkjet printhead, and allow the capper to move to the capping position in response to disengagement of the actuation arms with a trailing edge of the media.
