Abstract (en)
[origin: EP1995196A2] A method is provided of operating a document feeding mechanism having a document feed path which extends through a nip defined between an advance roller (32) disposed on one side of a document feed path and a retard roller (36) disposed on an opposite side of the document feed path. The method comprises detecting a multi-feed condition in which a first document (60) and a second document (62) overlapping the first document have been fed through the nip from an upstream end of the document feed path to a downstream end of the document feed path, and controlling operation of the advance roller (32) and the retard roller (36) such that the second document (62) is driven backwards through the nip to allow the first document (60) to be fed through the nip by itself in a non-overlapping manner without any human intervention.
