Despite the convenience and speed of email and instant messaging, fax machines are still used every day in some industries. But, what is a fax machine? What is a fax machine used for? And, how does a fax machine work? Here’ we’ll answer these questions and explain how to use a fax machine. 

What is a Fax Machine?

A fax machine is also known as a facsimile machine. It scans, transmits, and reproduces documents remotely. The fax machine revolutionized document sharing by facilitating the near-instant transfer of physical documents over long distances. Essentially, a fax machine converts scanned images or text into electronic signals, transmitted via telephone lines, and reconstructed at the receiving end.

Understanding fax machines is key to appreciating the evolution of telecommunications.

A brief history of the fax machine shows us that fax machines have evolved significantly since the mid-20th century. Originally analog, modern fax machines now leverage digital technology for clarity and efficiency. Moreover, the idea of transmitting images over long distances dates back to before the 1960s when fax machines became widely used.

How Does a Fax Machine Work?

How fax machines work is by converting text from a printed document into digital data, which is then transmitted as audio tones over phone lines to another fax machine. The receiving fax machine decodes these tones back into text, recreating the original document. Despite being a technology over 150 years old, faxing remains surprisingly relevant today.

Various types exist, depending on where you find a fax machine, from standalone devices to multifunction printers. Despite differences, the essence remains: to convert information into electronic data for transmission.

While you might not be familiar with traditional fax machines, modern alternatives like online fax services, fax by email, or mobile fax apps have adapted this old technology for contemporary use. This enduring relevance highlights the staying power of fax communication. 

How to Use a Fax Machine

While the instructions may vary from machine to machine, the process is usually pretty straightforward and involves a series of steps. 

Using a fax machine requires a dedicated phone line, and both the sending and receiving fax machines must be compatible and properly configured.

Here’s how to send a fax using a fax machine

  1. Allocate desk space similar to that needed for a household printer.
  2. Plug the fax machine into a power outlet.
  3. Connect the telephone cable to the back of the fax machine.
  4. Install ink or toner in the machine.
  5. Load thermal paper into the paper tray.
  6. Press the power button to turn on the fax machine.
  7. Lift the fax machine’s handset to check for a dial tone; troubleshoot if no dial tone is heard.
  8. Place your document(s) in the feeder tray, following the indicated face-up or face-down orientation.
  9. Dial the recipient’s fax number using the fax machine’s keypad.
  10. Press the “Send” or “Fax” button to initiate the scanning and transmission process.
  11. Wait for a confirmation page to print out indicating successful transmission.
  12. Retrieve your documents from the output tray.
  13. Review the confirmation page for any error messages or ensure it states “completed.”

If you encounter any issues during setup or while sending a fax, refer to your fax machine’s user manual for specific troubleshooting steps.
