A nozzle guard (80) for an ink jet printer printhead with an array (14) of nozzles (10). The nozzle guard (80) has an array of apertures (84) individually corresponding to the nozzle array (14). The ink droplets are ejected through the apertures (84) and onto the media to be printed. A wiper blade (143) sweeps dust and residual ink (144) stuck to the exterior surface (142) of the nozzle guard (80) characterized in that the exterior surface has one or more recesses (146) encompassing a group or pod of the apertures (84) to prevent the wiper blade (143) from engaging the exterior surface (142) immediately adjacent any of the apertures (84) in the pod.

La présente invention concerne un capot (80) de buses destiné à une tête d'impression d'imprimante à jet d'encre pourvue d'un réseau (14) de buses (10). Ce capot (80) de buses possède un réseau d'orifices (84) qui correspondent individuellement au réseau (14) de buses. Les gouttelettes d'encre sont éjectées sur le support à imprimer à travers ces orifices (84). Un balai d'essuie-glace (143) balaye la poussière et l'encre (144) résiduelle engluées sur la surface (142) extérieure du capot (80) de buses. Cette surface extérieure possède une ou plusieurs parties en retrait (146) entourant un groupe ou une nacelle des orifices (84) de façon à empêcher le balai d'essuie-glace (143) d'entrer en contact avec la surface extérieure immédiatement contiguë des orifices (84) de cette nacelle.
