ABSTRACT:
An enhanced sheet stripping method and apparatus for stripping toner image carrying copy sheets from a surface of a moving heated fusing member forming a fusing nip. The apparatus includes (a) a moving assembly for moving a cut sheet towards the fusing nip; (b) a sheet curling device positioned upstream of the fusing nip relative to movement of the cut sheet for inducing a desired pre-curl in the cut sheet before the cut sheet enters the fusing nip; and (c) a sheet stripping device positioned downstream of the fusing nip for stripping the cut sheet from contact with the surface of the moving heated fusing member as the cut sheet exits the fusing nip. The method includes inducing a desired curl in the cut sheet before the cut sheet enters the fusing nip and enhanced stripping the cut sheet from contact with the surface of the fuser roll as the cut sheet exits the fusing nip.
