Online faxing has become the leading approach for sending faxes, yet traditional fax machines linked to landlines continue to be prevalent in industries such as finance, healthcare, and legal services.

These machines are still important despite the fact that they are being phased out, and online fax services, like https://comfax.com/, are increasingly popular due to their convenience. This article delves into the history, mechanics, and functionality of fax machines, offering a comprehensive perspective on their evolution.

The evolution of fax technology

The fax machine’s origins trace back to the mid-19th century, with Alexander Bain’s 1843 patent marking its inception. Early fax machines used telegraph lines but gained popularity in the 1960s when Xerox introduced machines transmitting over phone lines, revolutionizing the process. Modern fax machines retain the core principles of scanning, encoding, and transmitting, but are now more efficient and secure.

The scanning process

So, how do modern fax machines function? While they may seem complex, there is a simplicity in their operation. A fax machine scans a document and converts the scanned images or text into a bitmap, a series of tiny dots that can be black or white, representing the original image in a format suitable for transmission over phone lines.

This process might remind you of art lessons where images were created with dots varying in intensity and spacing. A bitmap operates on the same principle.

The scanning mechanism of a fax machine uses a Charge-Coupled Device (CCD), a series of light-sensitive sensors that convert the light and dark areas of a document into electronic signals. These signals are then translated into binary data — ones and zeros — corresponding to the black and white dots of the bitmap.

The receiving process

A fax machine converts scanned documents into binary data, which a modem transmits over a phone line as audible tones. At the receiving end, another modem converts these tones back into binary data, and the fax machine prints the reconstructed document. This process involves transmitting binary code through phone line tones.

How to use a fax machine

Sending a fax with a fax machine involves loading a legible document into the feeder, entering the recipient’s fax number accurately, adjusting settings if necessary, and pressing ‘Send.’ The machine then scans and transmits the document. A confirmation page will indicate success or failure of the transmission.

How to receive a fax

Receiving a fax involves ensuring your machine is powered, connected, and has enough paper and ink. Most modern machines automatically receive faxes, but older models may require pressing ‘Receive’ after hearing the fax tone. The machine converts the tones into data and prints the document, often providing a confirmation page to verify receipt.

What is online faxing?

Traditional fax machines have transformed into a more efficient, eco-friendly, and cost-effective method known as online faxing or internet faxing, available through platforms like comfax.com. Modern app design has revolutionized and simplified the faxing process, removing the need for bulky machines and dedicated phone lines.

If your recipient still uses a traditional fax machine, you can seamlessly send a fax to it through online faxing. This method leverages the internet instead of landlines, enabling users to send and receive faxes directly from computers, smartphones, or tablets.

Simply attach or scan a document using your smartphone, upload it to the app with the recipient’s fax number, and send. This process is quick, straightforward, and eliminates the need for ink, paper, or waiting in line.

Chances are you already have everything you need to send an online fax right now: an internet connection, a smartphone or web browser, and a subscription to an online fax service.
