ABSTRACT:
Washers are used for a pressure roll in a fusing system of an electrophotographic system that improve the functionality and durability of the pressure roll. These washers are made up of a rigid ring section having flexible (less rigid) fingers projecting from the inner periphery of the ring. This provides a more uniform pressure to be exerted in the pressure roll and, consequently, a more uniform nip for better handling and fusing.
