ABSTRACT:
A scuff separating device capable of feeding document sheets from the bottom of a stack includes a feed belt below and contacting the bottom of the stack. A retard roller rests on the belt and prevents double feeds. The retard roller and belt both have high coefficients of friction. A brake on the retard roller prevents rotation when more than one sheet is in the nip but permits rotation when one or no sheets are in the nip.
