The receiving fax machine interprets the tones and reconstructs the image, printing a paper copy. Early systems used direct conversions of image darkness to audio tone in a continuous or fax to pdf machine manner.

Since the 1980s, most machines modulate the transmitted audio frequencies using a digital representation of the page which is compressed to quickly transmit areas which are all-white or all-black. 1846 was able to reproduce graphic signs in laboratory experiments. He received British patent 9745 on May 27, 1843 for his “Electric Printing Telegraph. Bain’s design and demonstrated a telefax machine. Europe especially, since a widely noticed transmission of a wanted-person photograph from Paris to London in 1908, used until the wider distribution of the radiofax.

T Corporation “by a new process of transmitting pictures by electricity” sent 15 photographs by telephone from Cleveland to New York City, such photos suitable for newspaper reproduction. Previously, photographs had been sent over the radio using this process. New York to London on November 29, 1924 became the first photo picture reproduced by transoceanic radio facsimile. Commercial use of Ranger’s product began two years later.

Beginning in the late 1930s, the Finch Facsimile system was used to transmit a “radio newspaper” to private homes via commercial AM radio stations and ordinary radio receivers equipped with Finch’s printer, which used thermal paper. Sensing a new and potentially golden opportunity, competitors soon entered the field, but the printer and special paper were expensive luxuries, AM radio transmission was very slow and vulnerable to static, and the newspaper was too small. After more than ten years of repeated attempts by Finch and others to establish such a service as a viable business, the public, apparently quite content with its cheaper and much more substantial home-delivered daily newspapers, and with conventional spoken radio bulletins to provide any “hot” news, still showed only a passing curiosity about the new medium. Radio fax is still in limited use today for transmitting weather charts and information to ships at sea.

This model was superseded two years later with a unit that would truly set the standard for fax machines for years to come. Up until this point facsimile machines were very expensive and hard to operate. In 1966, Xerox released the Magnafax Telecopiers, a smaller, 46-pound facsimile machine. This unit was far easier to operate and could be connected to any standard telephone line.
