RESIDUE REMOVAL FROM NOZZLE GUARD FOR INK JET PRINTHEAD

摘要

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 (82) characterized in that the exterior surface (142) has a recess (146) individually associated with each of the apertures (86) for preventing residual matter (144) carried by the wiper blade (143) from lodging within the aperture (84).
