A mobile device including: (a) an inkjet printhead; (b) a print media feed path for directing a print medium past the printhead in a feed direction during printing; (c) a capping mechanism including a capper moveable between: a capping position in which the capper is urged into a capping relationship with the printhead; and an uncapped position in which the printhead is able to print onto the print medium, wherein in the uncapped position the capper is displaced away from the printhead; (d) a force transfer mechanism connected to the capper and configured such that a force provided by an edge of the print medium as it moves relative to the feed path is transferred to the capper by the force transfer mechanism, thereby to at least commence movement of the capper from the capped position to the uncapped position prior to the print medium reaching the capper.
