A capping mechanism is disclosed for a pagewidth printhead assembly having a pagewidth printhead (51) and a plurality of nozzles located along the printhead for delivering ink onto print media as it is transported past the printhead. The capping mechanism comprises a capping member (82) having a length corresponding substantially to that of the printhead (51) and an actuating mechanism (90) arranged to effect linear transitioning of the capping member (82) from a non-capping first position (fig. 9B) to a second position (fig. 9C) at which the capping member is located in nozzle capping engagement with the printhead.

La présente invention concerne un mécanisme de recouvrement pour un ensemble tête d'impression de largeur de page comportant une tête d'impression de largeur de page (51) et une pluralité de buses positionnées le long de la tête d'impression pour distribuer de l'encre sur un support d'impression lorsqu'il est transporté devant la tête d'impression. Le mécanisme de recouvrement comprend un élément de recouvrement (82) ayant une longueur correspondant sensiblement à celle de la tête d'impression (51) et un mécanisme d'actionnement (90) agencé pour effectuer une transition linéaire de l'élément de recouvrement (82) d'une première position, dite de non-recouvrement (figure 9B), à une seconde position (figure 9C) dans laquelle l'élément de recouvrement vient en prise avec la tête d'impression de manière à recouvrir les buses.
