UNEXPOSED AREAS/EDGE ERASE LAMP
To prevent a black band from occurring across both the leading and trailing
edges, and along the front and rear edges, of the electrostatic latent image,
31 LEDs of Unexposed Areas/Edge Erase Lamp LA3 are turned ON before
development takes place, thereby reducing to a minimum the unnecessary
potential on the surface of the PC Drum.
Because of the light path involved, this copier has this edge erasing cycle
between drum charging and exposure.
