Abstract
A method of curing a protective overcoat layer on the outermost portion of an organic photoconductor drum using dual curing process is provided. The first curing step applies either ionizing irradiation, such as with an electron beam or by gamma rays or applies non-ionizing irradiation such as ultraviolet light to the overcoated photoconductor drum. A mask or shield is sized to be placed over the print area of the initially cured photoconductor drum, thereby exposing the outermost edges of the photoconductor drum. The outer edges of the masked photoconductor drum is then exposed to a second curing step using non-ionizing irradiation such as ultraviolet light.
