ABSTRACT:
A media separator, that cooperates with a media pick to form a nip in a feed path of a media handling apparatus, supports a separation pad that includes first and second friction regions for movement relative to the media separator, against a bias force, in a feed direction of a sheet of media through the nip. The first and second friction regions selectively engage the sheet of media passing through the nip with a retard/separation force determined by the bias force, to retard and control a feeding operation of the sheet of media through the nip, and to feed plural sheets of media through the nip one at a time.
