Abstract

This disclosure relates to a release agent management system for a roll fuser apparatus 10. The fuser apparatus 10 comprises a heated fuser roll 12 and a pressure roll 14. A sump 16 containing a quantity of release agent material 18, such as silicone oil, is provided so that the material can be conveyed by means of a metering roll 20 and a rubber-coated donor roll 22 to the surface of the fuser roll. The release agent is metered to the desired thickness by a blade 24. Pressure engagement of the donor roll with the metering roll and the fuser roll is effected by a pivotable arm 26. An adjustable set screw 28 controls the compression of the donor roll 22 between the metering roll 20 and the fuser roll 12. Rotation of the metering and donor rolls is accomplished via the rotation of the fuser roll, which is positively driven by means not shown. As can be seen, the roll centers are disposed in a triangular pattern in order to keep the relationship of the metering roll 20, blade 24 and fuser roll 12 in a fixed position. The thermal expansion is taken up by the rubber coating of the donor roll 22.
