ABSTRACT:
A skip stroke wiping method of cleaning an inkjet printhead in an inkjet printing mechanism cleans a printhead that has an orifice plate, and first and second outboard regions located along two opposing sides of the orifice plate. In a bidirectional wiping routine, the ink residue is first wiped in a first direction from the orifice plate onto the first outboard region without touching the second outboard region. In a second wiping step, ink residue is wiped in a second direction opposite to the first direction from the orifice plate onto the second outboard region without touching the first outboard region. Thus, regions of the printhead having ink residue are skipped over in the wiping strokes to avoid contaminating the nozzles with previously wiped residue.
