ABSTRACT:
A heat and pressure roll fusing apparatus for fixing toner images to copy substrates. The apparatus includes a release agent management system (RAM) for applying release agent such as functional silicone oil to a heated roll of the apparatus. The RAM comprises a donor roll, a metering roll and a metering blade which cooperate to convey silicone oil from a sump to the surface of the heated roll. The metering roll which is contacted by the metering blade is provided with a helical groove which acts to scrape the tip of the metering blade as the metering roll rotates and move paper related residue dislodged therefrom to the end of the metering roll where it is collected for subsequent disposal.
