Abstract

This disclosure relates to a release agent management system for a roll fuser apparatus generally indicated by reference character 10. The apparatus comprises a fuser roll 12 to which silicone oil 14 is applied in order to counteract toner offset to the fuser roll. The fuser roll cooperates with a softer pressure roll 16 to fuse toner images 18 to a copy substrate such as plain paper 20.

This disclosure relates to a release agent management system for a roll fuser apparatus generally indicated by reference character 10. The apparatus comprises a fuser roll 12 to which silicone oil 14 is applied in order to counteract toner offset to the fuser roll. The fuser roll cooperates with a softer pressure roll 16 to fuse toner images 18 to a copy substrate such as plain paper 20.

The silicone oil which is contained in a sump 22 is applied to the surface of the fuser roll by.means of a rotating brush 24 which is adapted to be rotated in the opposite direction to that of the fuser roll. The brush engages one end of a wick 26 while the other end of the wick is immersed in the silicone oil. Thus, the brush picks up silicone oil from the wick and conveys it to the fuser roll surface. Since the brush rotates counter to the fuser roll the brush bristles strip the lead edge of the copy and deflect it down and away from the fuser roll. The brush fibers undergo a snapping or flicking action as they move out of the nip formed between them and the fuser roll. It is this action which yields the stripping action. The oil application rate is controlled by the brush fiber density and the velocity of the roll.
