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 ).
