ABSTRACT:
A limited drive force prefuser vacuum transport apparatus includes at least two sets of belts entrained around a vacuum plenum to provide a limited drive force on sheets being driven by the vacuum transport apparatus. One set of the belts is deliberately driven at a lower speed than the other of the at least two sets of belts in order to maintain the ability of limited slip of sheets on the vacuum belt transport, thus accommodating speed variations among components of a copier/printer including a photoreceptor, paper transport and fuser.
