ABSTRACT:
To remove an old photoresponsive or photoconductive selenium layer from a drum of a copy machine as preparation for the vacuum evaporation of a new photoresponsive layer thereonto, the drum is immersed in a hot fluid such as water, steam or liquid or vapor trichloroethylene or perchloroethylene. Due to the softening of the photoresponsive layer and the difference between the coefficients of thermal expansion of the photoresponsive layer and the drum material, the photoresponsive layer may be subsequently easily physically removed from the drum.
