The business took off, and its founders made a lot of money and received the credit they deserved for being daring visionaries.
Wire transmission[ edit ] Scottish inventor Alexander Bain worked on chemical mechanical fax type devices and in was able to reproduce graphic signs in laboratory experiments. The Pantelegraph was invented by the Italian physicist Giovanni Caselli.
He introduced the first commercial telefax service between Paris and Lyon insome 11 years before the invention of the telephone.
AroundGerman physicist Arthur Korn invented the Bildtelegraphwidespread in continental Europe especially, since a widely noticed transmission of a wanted-person photograph from Paris to London inused until the wider distribution of the radiofax.
Previously, photographs had been sent over the radio using this process. Radiofax Children read a wirelessly-transmitted newspaper in A photograph of President Calvin Coolidge sent from New York to London on November 29,became the first photo picture reproduced by transoceanic radio facsimile.
Also inHerbert E. 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. Also, it is also widely used within the medical field to transmit confidential patient information. This model was superseded two years later with a unit that would truly set the standard for fax machines for years to come.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. InXerox released the Magnafax Telecopiers, a smaller, pound facsimile machine. This unit was far easier to operate and could be connected to any standard telephone line.
This machine was capable of transmitting a letter-sized document in about six minutes.
The first sub-minute, digital fax machine was developed by Dacomwhich built on digital data compression technology originally developed at Lockheed for satellite communication. Very shortly after this, a new wave of more compact, faster and efficient fax machines would hit the market.
Xerox continued to refine the fax machine for years after their ground-breaking first machine. In later years it would be combined with copier equipment to create the hybrid machines we have today that copy, scan and fax. Some of the lesser known capabilities of the Xerox fax technologies included their Ethernet enabled Fax Services on their workstations in the early s.
Prior to the introduction of the ubiquitous fax machine, one of the first being the Exxon Qwip  in the mids, facsimile machines worked by optical scanning of a document or drawing spinning on a drum. The reflected light, varying in intensity according to the light and dark areas of the document, was focused on a photocell so that the current in a circuit varied with the amount of light.
This current was used to control a tone generator a modulatorthe current determining the frequency of the tone produced. This audio tone was then transmitted using an acoustic coupler a speaker, in this case attached to the microphone of a common telephone handset.
Computer facsimile interface[ edit ] InHank Magnuskifounder of GammaLinkproduced the first computer fax board, called GammaFax. Such boards could provide voice telephony via Analog Expansion Bus.
In some countries, because electronic signatures on contracts are not yet recognized by lawwhile faxed contracts with copies of signatures are, fax machines enjoy continuing support in business. Convenience-store fax machines commonly print the slightly re-sized content of the sent fax in the electronic confirmation-slip, in A4 paper size.
Such systems have the advantage of reducing costs by eliminating unnecessary printouts and reducing the number of inbound analog phone lines needed by an office. The once ubiquitous fax machine has also begun to disappear from the small office and home office environments.
Remotely hosted fax-server services are widely available from VoIP and e-mail providers allowing users to send and receive faxes using their existing e-mail accounts without the need for any hardware or dedicated fax lines. Personal computers have also long been able to handle incoming and outgoing faxes using analog modems or ISDNeliminating the need for a stand-alone fax machine.
These solutions are often ideally suited for users who only very occasionally need to use fax services.
In July the United Kingdom's National Health Service was said to be the world's largest purchaser of fax machines because the digital revolution has largely bypassed it. Since the Carterphone decisionmost fax machines have been designed to connect to standard PSTN lines and telephone numbers.
Analog[ edit ] Group 1 and 2 faxes are sent in the same manner as a frame of analog televisionwith each scanned line transmitted as a continuous analog signal. Horizontal resolution depended upon the quality of the scanner, transmission line, and the printer. Analog fax machines are obsolete and no longer manufactured.
Group 1 faxes take six minutes to transmit a single page, with a vertical resolution of 96 scan lines per inch. Group 1 fax machines are obsolete and no longer manufactured. Group 2 faxes take three minutes to transmit a single page, with a vertical resolution of 96 scan lines per inch.
Group 2 fax machines are almost obsolete, and are no longer manufactured.Fax (short for facsimile), sometimes called telecopying or telefax (the latter short for telefacsimile), is the telephonic transmission of scanned printed material (both text and images), normally to a telephone number connected to a printer or other output ashio-midori.com original document is scanned with a fax machine (or a telecopier), which processes the contents (text or images) as a single.
