In CVT arrangements such as that taught in United States Patent No. ,4,380,389 to Kingsley, handling of larger documents with slippery surfaces generally requires that spring pressure between frictional support fingers and a CVT roll be increased in order to provide a non-slip transport of the document by the CVT roll. However, the increased pressure on the roll results in increased drag on the drive motor and velocity errors which cannot be tolerated in raster inpuffoutput scanning applications.
