Abstract
A plurality of stripper fingers in a fuser assembly are provided to assist in preventing damage to the fuser roll caused by prior art fingers. In the present invention, skiis are positioned away back from the tip of the stripper finger. These skiis extend beyond the lower surface of the stripper finger and are enabled to lift the tip away from the fuser surface during a paper jam or hard stripping situation.

A fusing assembly useful in an electrophotographic marking apparatus comprising:
- a fuser structure and paper finger strippers configured to contact said structure with a spring force when urged against said structure,
- said structure selected from the group consisting of fuser rolls, fuser belts, and combinations thereof,
- said finger strippers comprising an elongated strip having at a first front end a stripping tip and behind said tip at least two bent elbow-shaped ski elements,
- said ski elements attached to and horizontally extending below said stripping tip, said elements configured to lift said stripping tip off the fuser structure when paper/substrates loads the said finger strippers.
