  • Patent number: 3989860
    Abstract: Disclosed is a method for repairing an electrostatographic photoreceptor comprised of a conductive substrate with a uniform layer of selenium on its surface. Scratches in the selenium layer of a depth less than its total thickness are filled with a photoconductive composite as repair material. When the combination of materials forming the composite are selected so as to provide discharge characteristics similar to those of selenium, the repaired photoreceptor will provide copies in which printout in the repaired areas is of the same quality as in the non-damaged areas.
