Abstract
A printhead cartridge has a generally box like shape, a recessed channel area on which a printhead is mounted, and an integrally formed wiper cleaning station. The wiper cleaning station includes a pair of spaced apart cleaning surfaces on right and left sidewalls for engaging a wiper, a pair of debris accumulation plateaus, and right and left recessed debris collectors which sandwich the recessed channel area and which are disposed below corresponding ones of the plateaus. The printhead cooperates with the right and left side walls to form right and left debris accumulation channels which extend into the right and left recessed debris collectors. A pair of spaced apart cutout areas are provided for allowing the wiper to disengage from the wiper cleaning station when the printhead stops and reverses its direction.
