Abstract

As shown in the drawing, document handling system 10 includes a vacuum manifold 12 with an aperture plate 14 for applying a vacuum to the backside of an apertured vacuum document belt 16. Belt 16 is entrained about a pair of opposed spaced rollers 18 and 20. Vacuum is provided by blower 22. Document belt 16 and plate 14 are mounted so that document 24 may be transported to transparent platen 26 of the electrophotographic printing machine. Belt 16 has a plurality of narrow elongated grooves.

As shown in the drawing, document handling system 10 includes a vacuum manifold 12 with an aperture plate 14 for applying a vacuum to the backside of an apertured vacuum document belt 16. Belt 16 is entrained about a pair of opposed spaced rollers 18 and 20. Vacuum is provided by blower 22. Document belt 16 and plate 14 are mounted so that document 24 may be transported to transparent platen 26 of the electrophotographic printing machine. Belt 16 has a plurality of narrow elongated grooves. Plate 16 includes a plurality of facetted reflectors, i.e., Fresnel reflectors. Belt 16 is transparent. This greatly increases the amount of light reaching the lens of the printing machine optical system and causes the areas to be super reflective. In this way, any images of the holes in belt 16 are washed out.

Holes are located in the bottom of the grooves.
