ABSTRACT:
An improved apparatus for duplex scanning using a paper path shorter than the length of paper to be duplexed allows a smaller duplexing ADF footprint, without decreasing scan quality. The apparatus includes a friction drive system which allows rollers to rotate with an exit shaft when exit said shaft rotates in a first direction or with a passing media sheet when said exit shaft rotates in a second direction.
