  • Patent number: 5278617
    Abstract: A release agent management system incorporated in an electrophotograpic printing machine having a heat and pressure fuser assembly with stripper fingers to aid in the removal of fused copies from the fuser roll. The fuser assembly includes a heated fuser roll, a pressure roll, a sump containing a quantity of release agent, a metering roll and a donor roll. The metering roll is immersed in a quantity of release agent and is in contact with the donor roll. The donor roll acts as the transport to transfer release agent from the metering roll to the heated fuser roll. The surface of the donor roll is provided with cutout grooved areas corresponding to the location of the stripper fingers on the fuser roll. These grooves result in a lesser amount of release agent being applied to the fuser roll in the area adjacent the stripper fingers.
