ABSTRACT:
A heated pressure roll fuser system is provided with a wick assembly which comprises a Nomex layer of material, a wool layer of material and a porous wiper pad. The wiper pad engages a heated fuser roll. One face of one end of the Nomex layer contacts the wiper pad, and the same face at the other end of the Nomex layer engages an oil applicator roll which rotates in an oil reservoir laterally spaced from the fuser roll. The wool layer is on top of the Nomex layer and engages the other face thereof. Both the Nomex layer and the wool layer wick oil to the wiper pad where oil passes by gravity through the wiper pad to the fuser roll. The wicking action of the wool layer assures a continuous supply of oil at the fuser roll on long copy runs of a xerographic machine in which it is utilized. The Nomex layer protects the wool from scorching.
