Abstract:

An electrophotographic printing machine for reproducing an original document with a copy thereof having additional indicia thereon. A means such as a movable occluder bar is used to mask a region of photoconductive member from the illuminating means to prevent discharge at that region. Then a means to discharge selectively the masked region reocrds a latent image corresponding to the additional indicia.
