Whats a G3 fax machine?
Most fax machines in use today are of the G3 type, and transmit data at speeds of up to 9,600 kbps. Although scanning, encoding, and compression techniques are performed digitally, the actual transmission is still performed by what is essentially a built-in analog modem. In 1991, error correction, improved data compression, and the higher speed of 14.4 kbps were added to G3. Fax modems for use with personal computers often feature the higher speed of 14.4 kbps, but the speed automatically falls back to 9,600 kbps when the receiving device does not support the higher speed. Two fax resolutions are usually provided, the standard 200 x 100 dpi mode, and a 200 x 200 fine mode.
