Abstract
A converter applique that fits onto and retrofits existing low priced plain paper electrostatic copiers is discussed herein. The applique of the present invention contains all of the additional elements needed to provide the full functionality of a plain paper facsimile transceiver. Additionally, the applique of the present invention removably mounts on a plain paper copier and converts it to serve as a facsimile transceiver while preserving the functionality of the copier even when the applique is in place on the copier. Further the applique of the present invention makes no electrical contact with the internal circuits of the copier, and only makes mechanical contact to the non-movable portions of the outer case of the copier where it is positioned precisely to align the laser beam in the applique with the photosensitive drum within the copier.
