What is Fax?
Fax, short for facsimile, is a technology that transmits documents over telephone lines. It converts a document into an electronic signal, transmits it to a recipient’s fax machine, and then reconverts the signal back into a printed copy.
History of Fax
- 1843: Alexander Bain invents the first fax machine, using a clockwork mechanism to transmit images.
- 1924: The first commercial fax machine, the “Telautograph,” is introduced.
- 1964: The first digital fax machine, the “Xerox Telecopier,” is released.
- 1980s: The development of Group 3 fax standards leads to widespread adoption.
- 1990s: The Internet and email begin to replace fax as the primary method of document transmission.
How Fax Works
- Scanning: The document is scanned by the fax machine, converting it into a series of black and white dots.
- Encoding: The dots are encoded into a digital signal, using a standard fax protocol.
- Transmission: The digital signal is transmitted over telephone lines to the recipient’s fax machine.
- Decoding: The recipient’s fax machine decodes the signal and converts it back into a series of dots.
- Printing: The dots are printed onto paper, recreating the original document.
Types of Fax Machines
- Standalone Fax Machines: These are dedicated devices that only perform fax functions. They are typically found in offices and businesses.
- Multifunction Printers (MFPs): Many modern printers include built-in fax capabilities, allowing them to perform printing, scanning, copying, and faxing.
- Software-Based Faxing: This involves sending and receiving faxes through a computer program, using a modem or internet connection.
Advantages of Fax
- Reliability: Fax transmissions are generally reliable, even in areas with poor internet connectivity.
- Security: Fax transmissions are encrypted, making them more secure than email for sensitive documents.
- Legal Validity: Faxed documents are often considered legally binding, especially in certain industries.
- Wide Availability: Fax machines are still widely available, making it easy to send and receive faxes.
Disadvantages of Fax
- Slow Speed: Fax transmissions can be slow, especially for large documents.
- Cost: Fax machines and fax Services can be expensive.
- Limited Functionality: Fax machines are limited to sending and receiving documents, unlike email which allows for attachments, formatting, and other features.
- Environmental Impact: Fax machines use paper and ink, contributing to environmental waste.
Fax Protocols
- Group 3 Fax: The most common fax protocol, used by most modern fax machines.
- Group 4 Fax: A digital fax protocol that uses high-speed data connections, but it is not widely used.
Fax Numbers
A fax number is a unique telephone number assigned to a fax machine. It is used to identify the recipient of a fax transmission.
Sending a Fax
- Prepare the document: Ensure the document is clear and legible.
- Dial the fax number: Enter the recipient’s fax number on the fax machine.
- Place the document in the fax machine: Follow the instructions on the machine to load the document.
