Full Form of FAX :
FAX Full Form is FACSimile. It is also called as Telefax or Telecopying. FAX represents the scanned-printed copy of an image or text sent using the telephone number. Here, the telephone number is linked to the output FAX device. In simple terms, FAX machine can receive or send texts or images over a specific telephone line. FAX machine works by digitizing the images or texts. This means it divides the text or image into small grids of dots. It then transfers the images through bit maps. These bit maps are then transmitted as audio-frequency tones through the telephone lines.
The receiver’s FAX machine then interprets these bitmaps reconstructs the image or text and prints it on a paper. In order to send the FAX message, the sender should know the FAX number of the receiver. FAX machines were used as the preferred mode of official communication till the 1990’s.Of late, FAX technology has faced huge competition from the Internet tools and systems like E-mail, Text Messaging etc. However, in countries where electronic signatures are still not approved, FAX machines still have a demand.
FAX Full Form – Additional Information
Facsimile, also known as telefax or telecopying, or telefacsimile, is basically a mode of telephonic transmission, which transmits scanned material (in text as well as images format) to a telephone number, which is connected to an output device such as a printer. The original printed material is scanned with the help of an instrument called the fax machine, which is also known as telecopier. This machine undertakes processing of the contents of the both text and images printed material in the form of a single graphic image and conversion into a bitmap.
This bitmap is then transmitted via the telephone system as audio frequency tones. The fax machine on the other end that receives the transmission causes interpretation of the tone and reconstruction of the image obtained and makes a copy of it. In the early times, many fax machines were able to cause modulation of audio frequencies with the help of digital representation. FAX is an important invention contributed by mankind and is, therefore, has many important aspects that must be known. It is regarded as one of the key inventions that had expedited transmission of information among people and organizations. So here are five points about FAX that everyone must know about:
Wireless transmission and FAX
Under this head, we shall explore the history behind wireless transmission and production of facsimile by the same. Richard Ranger, who was working in the capacity of a designer in the Radio Corporation of America (abbreviated as RCA), invented the first wireless photoradiogram, also known as transoceanic radio facsimile, in the year 1924. This invention pioneered modern day fax machines. The first facsimile produced by this invention was that of a picture of the then President Calvin Coolidge. The invention was however put to commercial use only after two years later.
In the same year (1924), Herbert Ives, who worked for AT&T Corporation, managed to successfully transmit and produce the first ever color facsimile with the help of color separations. In the late 1940s, there was successful miniaturization of these radio receivers and they eventually began to be used by the Western Union. In the 1960s, the army of the United States of America (Abbreviated as the USA) made the transmission of the first photograph by means of satellite facsimile from the Deal test Site to Puerto Rico. The satellite used was the Courier Satellite. Today, the use of radio fax is very limited. It is limitedly used for the transmission of weather charts and maritime information.
Telephone Transmission and FAX
Telephone transmission happened late. In the year 1964, the Xerox Corporation patented and introduced arguably the first ever commercialized version of the modern day fax machine. It introduced it under the name Long Distance Xerography (abbreviated as LDX). Then, following its introduction, many highly advanced fax machines emerged, which completely overshadowed the presence of LDX. For quite some time, these machines were very expensive and put to use only by large enterprises and government offices. These machines were cumbersome and difficult to operate. In the year 1966, the Xerox Corporation introduced a compact, easy to use a version of the fax machine under the name Magnafax Telecopier.
This machine had the capability to conduct transmission of the letter-sized document in six minutes. Eventually, Dacom when on to introduce the first sub-minute fax machine whose working mechanism was based on digital data compression technology. This technology was essentially developed for satellite communication at Lockheed. By the year 1970, many companies entered the market of fax machines, including Japanese companies, which paved the way for easy to use, more compact and efficient fax machines. There were modifications done to the fax machines and people had many options to choose from.
Fax in the post-modern era
Fax machines are facing stiff competition from latest inventions, which are essentially internet based alternatives such as e-mail services. There is still a prevalence of fax machines, though, as many large organizations still maintain them for official purposes. For example, several countries do not recognize electronic signatures on contracts but recognize fax contracts with signature copies. In Japan, fax machines are particularly in vogue and used extensively for business purposes, especially in convenience stores.
Latest developments have caused substitution of freestanding fax machines with fax servers that receive and store incoming faxes electronically and then route them to the concerned user by means of e-mail or printout. This is an advantageous alternative, as it reduces the cost of paper and number of analog phone lines.
Despite efforts made by fax manufacturers, these machines are dying out. New inventions are more capable and efficient in undertaking similar functions. The Internet, the toughest competitor, has accumulated greater recognition with time. It is time that advanced incorporations were made into the working mechanism of fax machines or the technology will become obsolete.
As mentioned above, The Internet has become a great alternative to fax machines. In order to remain in the market, internet fax has been introduced. It is basically an internet fax service, which facilitates users to transmit and receive faxes with the help of an e-mail account. The faxes can be received on personal computers and laptops. In this case, there is no need of fax machine, fax server, and any software. Such faxes are attached in the form of PDF or TIFF files and can be retrieved anytime whenever the user has access to the internet.
In order to use this service, there is no need of paper or a fax line. Thus, it is a convenient alternative to a typical fax machine. Apart from this, there are softwares available that allow users to perform the aforementioned actions. There are applications that can be downloaded in cell phones that offer services of a fax machine. Such applications utilize internal camera of the phone to scan fax material for the purposes of uploading or importing.
Printing process of fax machines
Early fax machines used to make use of thermal printers having rolls of thermal paper installed as a part of their printing technology. However, since the 1990s, there has been a major transition from the use of thermal papers to plain paper faxes such as inkjet printers, laser printers, and thermal transfer printers. The advantage of an inkjet printer is that it is affordable. There is a standard for faxing in a color known as ITU-T30e however; it is not universally supported.
