Abstract

A method and system for reducing contamination build-up within a fuser roll system are disclosed. The method and system includes a donor roll in rotational combination with a fuser roll. The donor roll can be configured to transfer a toner release agent to the fuser roll to reduce toner build-up on the surface of the fuser roll. A grounded static brush can be located proximate to the donor roll. The grounded static brush can be configured to inductively remove electrostatic discharge from the surface of the donor roll. The reduced electrostatic reduces contamination build-up on the fuser roll, and therefore increases the cycle life of the components of the fuser roll system.
