Fax is a telecommunications technology that allows for the transmission of printed or handwritten documents over long distances via telephone lines. It converts the physical document into electronic signals that can be transmitted and reproduced at the receiving end.

Key aspects of fax technology:

  1. Document Transmission: Fax machines or fax software send scanned or digitally created documents from the sender’s location to the recipient’s fax machine or computer.
  2. Telephone Lines: Fax machines use standard telephone lines to transmit the document as analog signals.
  3. Physical Documents: Fax machines require physical documents to be scanned or fed into the machine for transmission.
  4. Hard Copies: At the receiving end, the fax machine prints a hard copy of the transmitted document.
  5. Security: Since fax transmissions travel over phone lines, they are generally considered secure and private, as long as the phone line is not compromised.
  6. Reliability: Fax technology has been widely used for decades and is known for its reliability in transmitting documents.
  7. Physical Fax Machines: Traditional fax machines are standalone devices that require paper, ink, and a phone line connection.

Fax technology enables the transmission of documents in their original format, allowing for signatures, annotations, and other handwritten or printed information to be accurately reproduced at the receiving end.

How Does Traditional Fax Work?

Traditional fax works by converting physical documents into electronic signals that can be transmitted over telephone lines to a receiving fax machine. Here is how it works:

  1. Document preparation: The document to be faxed is placed in the document feeder or on the glass surface of the fax machine.
  2. Dialing: The sender sets the recipient’s fax number on the fax machine and initiates the transmission.
  3. Scanning: The fax machine scans the document, converting it into a bitmap image.
  4. Encoding: The scanned image is encoded into a digital format using a fax modulation scheme, such as Group 3 or Group 4 compression.
  5. Transmission: The encoded digital data is sent over a telephone line to the receiving fax machine.
  6. Reception: The receiving fax machine decodes the transmitted data, reconstructing the image.
  7. Printing: The reconstructed image is printed on the receiving machine.

Traditional fax machines require a telephone line connection and physical documents to be scanned and transmitted. They are widely used in offices and industries where physical signatures or paper documents are necessary.

Suggestions: If you frequently need to send and receive documents, consider using efax services that allow you to send and receive faxes digitally without the need for a physical fax machine. Efax offers convenience, cost-saving, and accessibility compared to traditional fax machines.
