ABSTRACT:
An improved air stripping device for stripping copy sheets from the surface of an elastomeric fuser roll surface in which copies are fused under heat and pressure. The improved air stripping device utilizes the deformation in the elastomeric surface resulting from the pressure to strip the copy sheets without directly contacting the fuser roll surface. One or more apertures are formed in the tip portion of the stripping device which are connected to a source of air pressure. The tip portion can be either flat or curved and is positioned at an acute angle relative to tangential direction from which the copy sheet is stripped from the fuser roll surface which undergoes a rippled effect from the air pressure to facilitate the stripping of the copy sheets therefrom.
