Abstract

A xerographic copying machine 10 having a photoreceptor 12 mounted for movement around a closed path and a transfer corona generating device 14 has an improved paper feeding and registration system 16 for feeding copy sheets from a stack 18 to the photoreceptor for the transfer step. The system 16 includes a registration belt 20 mounted for movement around a closed path, the belt having two registration fingers 22 mounted thereon. A copy sheet fed from the stack 18 by a feed roller 24 is directed by gravity to the bottom of a paper guide 26. Because the photoreceptor 12 and the registration belt 20 are synchronized in their movement, at the proper time the registration fingers 22 riding in slots 28 lift the copy sheet upward by the trailing edge to the transfer corona generating device 14.
