Abstract
A media transport unit includes an envelope transport structure that utilizes support fingers directly under the envelope. The support fingers are canted toward the center line of the paper path. The envelope flap passes over the support fingers at an angle that prevents the envelope flap from catching a support finger and potentially causing envelope wrinkling or a jam. The support fingers on either side of the area over which the envelope passes are canted away from the center line of the paper path to prevent the edges of full width media from catching the surface of a support finger.
