Abstract

A printhead maintenance facility for an inkjet printhead, having a wiper member for contacting a nozzle face on the inkjet printhead, the wiper member having a resilient blade with the distal edge configured to flex upon contact with the nozzle face, a doctor blade and, a maintenance drive configured to wipe the wiper member over the nozzle face and then past the doctor blade. The resilient blade flexes to pass the doctor blade and, upon disengagement of the resilient blade and the doctor blade, the resilient blade springs back to its quiescent shape thereby projecting contaminants from its surface.
