  • Patent number: 5247591
    Abstract: The present invention includes an open-ended set of cover sheet forms that may be readily interpreted by the fax server system. In this system a first standardized cover sheet is designed to accept hand printed characters. This first cover sheet is then transmitted to a special fax server as part of this invention to create an alternative, fully detached cover sheet for automatic transmission to its specific recipient. Labor is minimized by allowing the sender to hand print a minimal amount of highly constrained telephone numbers, or the initials of the recipient onto a draft cover sheet when a mailing list has been previously stored in the memory associated with the special fax server.

  • Patent number: 5097350
    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.
