ABSTRACT:
A reproducing apparatus for producing a toner image on a supporting substrate including an image fuser or fixer device which elevates the temperature of the toner to a level at which it at least softens, and sheet delivery exit rolls adjacent to the toner fixing device for transporting a sheet to the output station. The sheet delivery roll in contact with the toner image side of the sheet is provided with a cleaning pad for cleaning the surface of the exit roll of toner and debris which is made from inflammable resiliently compressible flexible abrasive fibers. Typically the pad is impregnated with abrasive particles. In a preferred embodiment the cleaning pad is also impregnated with a toner release fluid and is mounted on top of the top transport roll and extends the length of the top transport roll and rests thereon by virtue of its own weight.
