Abstract

A method of cleaning and coating a used organic photoconductive drum is disclosed. Using this method remanufacturers can reliably reuse certain used organic photoconductive drums which could not be reused without this method. The method comprises providing a used organic photoconductive drum, cleaning the surface of the used organic photoconductive drum, applying a new surface layer comprising a non-volatile non-polar dielectric fluid such as a silicone oil with a viscosity of less than 200 cSt at 40 degrees Celsius. The resulting liquid surface on the used organic photoconductive drum provides wear resistance, and improved electrical characteristics allowing the used organic photoconductive drum to be used at least a second time.
