Abstract
In an electrophotographic marking system a guard is provided to prevent fingerprint smears or markings on a platen glass. When fingerprint images are made, oil and other debris from the fingers mark the platen and cause subsequent images to reproduce these markings. This guard protects the platen from said marks via a convenient and economical expedient.
