  • Patent number: 6091924
    Abstract: A fuser release agent management (RAM) system for applying release agent to a fusing apparatus is provided. The Ram system includes an application member for applying release agent to an external surface of a movable internally heated fusing member, and supply source for supplying release agent to the application member. Importantly, the RAM system includes a heating and release agent redistributing member mounted into contact with the external surface of the internally heated fusing member for additionally heating the external surface and release agent thereon, and for redistributing and smoothing out the release agent thereon, thereby eliminating an interdocument agent banding problem, and differential gloss ordinarily created by areas of unredistributed release agent thereon.

  • Patent number: 5819148
    Abstract: A heat and pressure fuser and RAM system therefor. The RAM system includes a metering roll, thin film and a metering blade supported for effecting intimate contact between the metering roll and the thin film. The thin film is supported for movement from a supply reel to a take-up reel for periodic movement of a new portion of the film into contact with the metering roll. In this manner, contamination in the area of contact between the metering roll and the thin film is minimized. Moreover, the thin film which has a high surface tension, minimizes blade wear.
