Abstract
An electrophotographic typewriter comprises a housing on which are mounted an alphanumeric keyboard, a flat-plane display unit, a paper feed tray and a paper output tray. A paper feed path is routed through an electrographic print unit, located in the housing, and comprises a photoconductive drum surrounded by a charging unit, an optical print head, a developing unit, a transfer unit, an erasing unit and a cleaning unit arranged in sequence about the photoconductive drum. An electronics package processes the alphanumeric input data to generate the flat-plane display and the outputs to the optical print head. Hard paper copy is produced where the paper feed path passes between the photoconductive drum and the transfer unit.
