  • Patent number: 5267008
    Abstract: A composite friction feed roll includes one material which feeds fresh paper well and another material which reliably feeds paper which has passed through fusing and has oil on its imaged surface. Such a roll will feed deplex and fresh paper or inserts equally reliably. Suitable material combinations would be silicone rubber which handles fused copies with ease, but has limited life feeding fresh or virgin paper because it collects fibers from fresh paper, and isoprene which is long lived handling fresh paper, but is rapidly contaminated by fuser oil. In the steady state condition, silicone regions will be primarily active in feeding duplexed paper while the isoprene oil contaminated, while in the plain paper feeding case, isoprene regions will be primarily responsible for feeding while the silicone becomes paper debris contaminated.
