Abstract
An angular wiping system is provided for removing ink residue from an inkjet printhead installed in an inkjet printing mechanism. By canting a wiper blade in opposite directions as the blade moves through a bi-directional wiping stroke, a nozzle portion of the ink-ejecting orifice plate is wiped on both passes of the blade. A pair of non-ink-ejecting side cheeks of the orifice plate laying on opposite sides of the nozzle portion are each wiped once during the bi-directional wiping stroke, with one cheek being wiped while the blade travels in a first direction, and the other cheek being wiped when the blade travels in a direction opposite to the first direction. An inkjet printing mechanism having the angular wiping system and method of wiping using this system are also provided.
