AIR-BEARING PHOTORECEPTOR BACKER BAR FOR ELIMINATING TRANSFER STREAKS

摘要

PROBLEM TO BE SOLVED: To provide an apparatus for eliminating transfer streaks in a printing system comprising a hollow transfer backer bar including sealed ends.SOLUTION: A transfer backer bar 200 includes a plurality of holes 210, and the holes are spaced along a photoreceptor supporting surface of the transfer backer bar. Air pressure can be applied within a hollow transfer backer bar thereby creating an air flow outward through the holes. The air flow contacts the underside of a photoreceptor and floats the photoreceptor on a cushion of air flow during transfer of an image to paper.
