Cleaning apparatus for roll fuser
First Claim
1. Fuser apparatus for fixing toner images to substrate material, said apparatus comprising:
- a pair of nip-forming members between which said substrate material moves with said toner images contacting a heated one of said nip-forming members;
means for elevating the surface temperature of said heated member to thereby render said toner images tacky;
cleaning means for removing contaminants from the surface of said heated member;
a combination mixing and tacky material supply member supported for contact with said cleaning means to thereby effect thorough mixing of contaminants with tacky material, said tacky material comprising a polymeric material which is tacky at the operating temperature of said fuser apparatus; and
a smoothing member operatively engaging said combination mixing and supply member for maintaining a substantially uniform surface on said mixing and supply member;
said smoothing member comprising an adhesive surface.

Abstract
A contact fuser assembly for use in electrostatic reproducing apparatus, said assembly including a heated fuser roll structure cooperating with a backup roll to form a nip through which copy sheets or substrate material having toner images thereon move with the toner images contacting the heated fuser roll structure. The fuser assembly is characterized by the provision of a cleaning arrangement comprising a roll having a tacky surface which is adapted to contact the fuser roll structure to thereby remove toner and other contaminants therefrom with subsequent embedding of the contaminants in the tacky surface. The cleaning arrangement is further characterized by the provision of means for maintaining the effectiveness of the cleaning arrangement.
