ABSTRACT:
A printhead wiper for ink-jet printers molded from an elastomer and including a wiping beam having a wiping edge formed at one end of the beam. The other end of the beam is integral with a base. A hole through the beam near the base decreases beam stiffness. A higher durometer elastomer may thus be used without applying excessive wiping force to the printhead. In another embodiment the wiper includes a pair of wiping blades each of which have wiping edges for wiping a printhead traveling thereby. The first wipe removes pooled ink and debris and spreads viscous ink while the second wipe further the spread ink before it can retract to its former drop or pooled configuration.
