Abstract

Certain known vacuum document handlers for copiers have plural non-porous sheet transporting belts covering and moving over partially evacuated pneumatic grooves in a plenum surface overlying the copier platen. Smaller transverse grooves may then apply the partial vacuum from these main vacuum grooves out from under the belt edges to the areas between the belts to attract a sheet to the belts. E.g., U.K. Application No. 8800720 filed Jan. 13, 1988 by Peter Roy Watson.
