Abstract
A capping mechanism is disclosed for a pagewidth printhead having a plurality of nozzles located along the printhead and arranged to deliver ink onto print media which, in use, is transported past the printhead. The capping mechanism incorporates a capping member which has a length corresponding substantially to that of the printhead and which is configured to contact the printhead in nozzle capping engagement, and a pivotal carrier supporting the capping member. An actuating mechanism is provided and arranged to effect pivotal movement of the carrier back and forth between a first position at which the capping member is located remotely with respect to the printhead and a second position at which the capping member is located in contact with the printhead. The capping member is pivotally mounted to the carrier and is arranged to pivot relative to the carrier during back and forth transitional movement of the carrier between a transition position and the second position, where the transition position is located intermediate the first and second positions.
