What It Is
The fax machine is a device that allows for the transmission of hard-copy documents from one point to another over a communication line. These documents include things like reports, illustrations, written letters and photographs.
How It Works
The transmitting fax first scans the document, turning it into a series of electrical impulses. This information is then sent via phone, cable or other communications system to a receiving fax machine, which decodes the information and prints it out.
The first fax patent was awarded in Britain in 1843 to Alexander Bain for his device that used two pens, two pendulums and wire that could image on an electrically conductive surface. The technology evolved for more than a century, until the late 1980s, when the number of fax machines jumped from 300,000 to four million.
Smaller, faster fax machines became as popular in businesses as their copy machines. Prior to extensive e-mail use, fax machines where the best way to transmit information in seconds or minutes, eliminating the need for overnight or courier services.
There are now many services that allow you to send faxes via the Internet. Documents are forwarded to your e-mail rather than a fax machine. Many businesses have eliminated their fax machines and are using the Internet for faxing.
