Facsimile technology and xerography

Although Arthur Korn, the German inventor transmitted first pictures electronically in 1902, the first functioning fax machine that adapted telephone circuits for picture transmission using telephotography debuted in 1924: A photography transparency was scanned into electrical signals that indicated the shades of the image. This data was transmitted by telephone onto a receiving sheet of photographic negative film and then developed in a darkroom.

There is a huge difference between the world's first telegraph maschine and a modern fax mashine, isn't there?There is a huge difference between the world's first telegraph maschine and a modern fax mashine, isn't there?

In 1949, a xerographic copier was introduced to allow an exact replication of an image to be made. Chemical innovations in facsimile technology include new toners and inks, advanced paper technology, and organic photoreceptor technology in the 1970s.

Due to high voltage, most photocopiers, especially the older types, emit toxic ozone (O3) gas during operation. Ozone may also be produced in a natural way, for instance when a lightning flashes or the sun shines.
