A capping mechanism (21) for a printhead having a capping member (29) which has a length corresponding substantially to the length of the printhead and which is configured to contact the printhead in nozzle capping engagement, and a pivotal carrier (30) supporting the capping member. An actuating mechanism (31) 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, wherein the transition position is located intermediate the first and second position.

La présente invention concerne un mécanisme de recouvrement (21) pour une tête d'impression comportant un élément de recouvrement (29), dont la longueur correspond sensiblement à la longueur de la tête d'impression et qui est configuré pour entrer en contact avec la tête d'impression en venant en prise avec celle-ci de manière à recouvrir les buses, et un support pivotant (30) supportant l'élément de recouvrement. Un mécanisme d'actionnement (31) est prévu et agencé pour effectuer un mouvement pivotant du support d'avant en arrière entre une première position, dans laquelle l'élément de recouvrement est éloigné de la tête d'impression, et une deuxième position, dans laquelle l'élément de recouvrement est en contact avec la tête d'impression. L'élément de recouvrement est monté de façon pivotante sur le support et est agencé pour pivoter par rapport au support au cours d'un mouvement de transition d'avant en arrière du support entre une position de transition et la deuxième position, la position de transition étant située entre les première et deuxième positions.
