ABSTRACT A feeding and transport system (13, 14) positively feeds discrete media elements (A) to be addressed (such as envelopes) past a number of print heads (16) in a positive manner to maintain consistent and proper alignment of the printed text on the media elements. First and second feed rollers (24, 30 or 138) feed the media elements (A) to a pair of pinch rollers, the operation of the first roller being interrupted once a media element reaches a predetermined position. A selector bar (33 or 132) with abrasive strips (34) or annular resilient rings (134) is associated with the second feed roller (30 or 138). The pinch rollers feed the media elements (A) onto endless transport belts (42), with transport wiper plates (62) disposed on top of the belts to hold the media elements in contact with the belts. The transport wipers comprise plates mounted by levers (69, 70) at opposite ends in such a way that an element may easily move under a plate, but is held tighter by the plate as it moves along it. At the end of the transport belts (42), an exit roller (118) holds the envelopes generally horizontal until they have almost completely cleared the belts, so that they do not smear previous envelope addresses.
