Abstract
The charging roller (42) and push plates (44) are spring mounted to the lid (36) of the printer. When the lid is closed, the plates push plungers (11) down to rotate crank arms (23), which open a shutter (7) in electrophotographic cartridge (1). This holds the cartridge in place and provides both a resilient, protective cushion for the cartridge and a pop-up action to the lid.
