Fax varied text

faqs sometimes called tellico p or telefax is the telephonic transmission of scanned printed material normally to a telephone number connected to a printer or other output device the original document is scanned with a fax machine which processes the contents as a single fixed graphic image converting it into a bitmap and then transmitting it through the telephone system in the form of audio frequency tones 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 analog 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 history wire transmission Scottish inventor Alexander bein worked on chemical mechanical fax type devices and in 1846 was able to reproduce graphic signs in laboratory experiments he received Peyton 9700 and 45 on May 27 1843 for his electric printing Telegraph Frederick bakewell made several improvements on Baines design and demonstrated a tele fax machine the pan telegraph was invented by the Italian physicist Giovanni casely he introduced the first commercial tele fax service between Paris and Leon in 1865 some 11 years before the invention of the telephone in 1881 English inventor shelford Bidwell constructed the scanning photo Telegraph that was the first tele fax machine to scan any two-dimensional original not requiring manual plotting or drawing around 1900 German physicist Arthur corn invented the bill Telegraph widespread in continental Europe especially since a widely noticed transmission of a wanted person photograph from Paris to London 19 08 used until the wider distribution of the radio facts its main competitors were the Berliner graphi by Edwin first then since the 1930s the hell schreiber invented in 1929 by german inventor rudolf hell a pioneer in mechanical image scanning and transmission the 1888 invention of the Telegraph by elisha gray marked a further development in fax technology allowing users to send signatures over long distances thus allowing the verification of identification or ownership over long distances on May nineteen nineteen twenty-four scientists of the AT&T corporation by a new process of transmitting pictures by electricity sent fifteen 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 the Western Union desk fax fax machine announced in 1948 was a compact machine that fits comfortably on a desktop using special spark printer paper wireless transmission as a designer for the radio corporation of america in 1924 richard h ranger invented the wireless photo radiogram or transoceanic radio facsimile the forerunner of today's fax machines a photograph of President Calvin Coolidge sent from New York to London on November 29th 1924 became the first photo picture reproduced by transoceanic radio facsimile commercial use of Rangers product began two years later also in 1924 Herbert he Ives of AT&T corporation transmitted and reconstructed the first color facsimile using color separations around nineteen fifty two or so Finch facsimile a highly developed machine was described in detail in a book it was never manufactured in quantity by the late 1940s radio fax receivers were sufficiently miniaturized to be fitted beneath the dashboard of western union's Teleca telegram delivery vehicles in the 1960s the United States Army transmitted the first photograph via satellite facsimile to Puerto Rico from the deal test site using the courier satellite radio fax is still in limited use today for transmitting weather charts and information to ships at sea telephone transmission in 1964 Xerox Corporation introduced what many consider to be the first commercialized version of the modern fax machine under the name or long-distance sir ography 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 magna facts tellico pia a smaller 46 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 Dakin which built on digital data compression technology originally developed at Lockheed for satellite communication by the late 1970s many companies around the world entered the fax market very shortly after a new wave of more compact faster inefficient fax machines would hit the market Xerox continued to refine the fax machine for years after their groundbreaking 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 facts technologies included their Ethernet enabled fax services on their 8000 workstations in the early 1980s prior to the introduction of the ubiquitous fax machine one of the first being the exxon q WIP in the mid-1970s facsimile machines worked by optical scanning of a document or drawing spinning on a drum the reflected light varying an intensity according to the light and dark areas of the document was focused on a photo cell so that the current in a circuit varied with the amount of light this current was used to control a tone generator the current determining the frequency of the tone produced this audio tone was then transmitted using an acoustic coupler attached to the microphone of a common telephone handset at the receiving end a handset speaker was attached to an acoustic coupler and a demodulator converted the varying turn into a variable current that controlled the mechanical movement of a pen or pencil to reproduce the image on a blank sheet of paper on an identical drum rotating at the same rate computer facsimile interface in 1985 dr. Hank Magnus key founder of gamma link produced the first computer fax board called gamma fax fax in the 21st century although businesses usually maintain some kind of facts capability the technology has faced increasing competition from internet-based alternatives in some countries because electronic signatures on contracts are not yet recognized by law while faxed contracts with copies of signatures are fax machines enjoy continuing support in business in Japan faxes are still used extensively for cultural and grapheme ich reasons and are available for sending to both domestic and international recipients from over 81 percent of all convenience stores nationwide convenience store fax machines commonly print the slightly resized content of the sand fax in the electronic confirmation slip in a4 paper size in many corporate environments freestanding fax machines have been replaced by fax servers and other computerized systems capable of receiving and storing incoming faxes electronically and then routing them to users on paper or via an email 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 email providers allowing users to send and receive faxes using their existing email 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 ISDN eliminating the need for a standalone fax machine these solutions are often ideally suited for users who only very occasionally need to use fax services there are 17 million fax machines in the US one every four point four seven square miles
