Abstract
The present invention is directed to a shutter system for electrophotographic machines that effectively reduces the impact of ambient light on the photoreceptor, or image-bearing member. The shutter system of the present invention utilizes a shutter member that substantially covers the cartridge chamber when in a closed position. Preferably, the shutter member is disposed at the opening of the cartridge chamber. The shutter member is held in place by one or more support brackets and is biased to the closed position by one or more springs.
