Abstract

A two-stage document singulating apparatus includes first and second singulators disposed along a document feed path. The first singulator acts to separate individual documents from a stack which are subject to a stack advance mechanism force. The second singulator separates multifeeds that pass through the first singulator and which are no longer subject to the stack advance mechanism force.
