Abstract
A multibin, cut-sheet xerographic copier capable of operating in a simplex or a duplex mode, wherein sheets are fed from a selected sheet stack, one at a time, to the copier's transfer station, by a sheet feeding structure which includes a resilient combing wheel. The combing wheel is of a unique resilient construction, such that it exhibits a spring rate and damping factor which minimizes acoustical noise and enhances reliable, repeatable shingling of the top sheet of a stack to a closable sheet drive nip.
