ABSTRACT:
A xerographic machine and a method for xerographically producing hard copy by direct reflecting illuminative scanning of a hard copy and/or by code signal controlling an alpha-numeric character defining light beam exposing a selenium or cadmium sulfide coated xerographic surface. The light beam generator may comprise a laser or the like which is deflection and/or brightness controlled by signals generated by selectively operating the keys of a keyboard, wherein such signals are reproduced from an electronic memory and/or are received by shortwave or wire, such as in facsimile transmission. The machine is capable of producing copy from composite printed and electronic information, a combination of electronic data sources, keyboard operated means, one or more memories, direct transmitted reception or any combination thereof. In a particular form, the machine is adjacent to or part of a television terminal and may be programmed to automatically receive and xerographically print data transmitted to the terminal on telephone lines or by short wave and to automatically transmit digital or facsimile data.
