ABSTRACT:
A sheet handler for successively transporting sheet-like material units to and from processing stations in image processing devices such as printers, copiers, and scanners. The sheet handler includes an idler and driven cross-roller set. The rollers are preloaded so that a normal force exists between the rollers at the nip. The nip is positioned in a path for receiving the sheet like material units and to urge such units along the path and into alignment along a registration edge. Apparatus for adjusting the preloaded force are provided to thereby adjust the normal force on sheet-like material passing through the nip.
