Abstract

In xerographic copier/duplicators having automated feeding of the original document onto the platen, several methods for document transport are known. These include a white belt which either drags the document across the platen glass or sucks it against the moving vacuum belt. In such systems, the belt is worn as it is handled by drive rolls, it becomes soiled by contact with the back of documents and then transfers the soil onto the face of others. The belt also changes its frictional properties with use and is expensive to replace. Belts adapted for vacuum transports sometimes contain holes which are visible through thin documents and show prominently around the edges of small documents. The method of this disclosure will eliminate these shortcomings.
