A fax modem is a device that sends documents to a fax machine or another modem. It can be connected to a computer in three ways: through the motherboard, an external USB fax modem, or a parallel port. There is a special type of fax modem called a fax modem card, which is about the size of a credit card. This type of card is part of the PCMCIA family, also known as PC cards.

What Does Fax Modem Mean?

A fax modem is an electronic document transmission and reception device that can be attached to a personal computer. Apart from sending documents to fax machines or other fax modems, a fax modem is similar to a conventional modem. Certain fax modems can function as ordinary modems, though not all do. Fax modems can be either internal or external, just like conventional modems. Internal fax modems are also known as fax boards. Both the documents you receive and those sent with a fax modem are saved as files on your disk and must already be in an electronic format, i.e., a disk file. You need an optical scanner to convert photos on paper into fax documents.

The communications software included with fax modems is comparable to that of ordinary modems. Many features that standalone fax machines do not have are made possible by this software for the fax modem. For instance, you can simultaneously broadcast a fax document to multiple locations. Furthermore, fax modems offer several advantages over fax machines:

• Cost: Fax modems are less costly. Because there are no moving parts, they also require less maintenance. However, there is no cost benefit if you also need to buy an optical scanner in addition to the fax modem.
• Convenience: If the documents you wish to communicate are already in electronic format, fax modems are more practical. Printing the document is the first step in using a fax machine. You can mail it straight with a fax modem.
• Speed: Most fax machines do not support high data transmission rates of 9,600 bps; however, fax modems can nearly always send documents at this maximum speed.
• Picture quality: Because fax modem documents are sent in electronic format, their image quality is typically higher.

Whether you’re looking for the best fax modem or a specific fax modem driver, choosing the right one depends on your needs and how you plan to connect it to your computer.

Origin of Fax Modem

The term “modem” is a portmanteau of “modulator” and “demodulator.” Essentially, a modem is a device that converts digital signals from a computer into analogue signals suitable for transmission over telephone lines and vice versa. The fax modem, a specific type of modem, was designed to transmit facsimile (fax) data over standard telephone lines.

The concept of fax (short for facsimile) transmission dates back to the 19th century, with early experiments in telegraphy and imaging technologies. However, it wasn’t until the late 20th century that fax machines became commercially viable. The first fax modem, which allowed computers to transmit facsimile data over telephone lines, emerged in the 1970s, marking a significant milestone in the evolution of communication technology.

How to install a Fax Modem

To install a fax modem, follow these general steps, which vary slightly depending on whether you are installing an internal, external, or USB modem:

1. Installing an External USB Fax Modem

1. Connect the modem: Plug the modem into a power outlet if it has an external power supply. Connect the telephone cord to the modem and a phone jack.
2. Connect to the computer: Insert the USB cable from the modem into an empty USB port on your computer.
3. Install the driver: Upon connecting, your computer should detect the new hardware. If prompted, insert the installation disc that came with the modem or download the driver from the manufacturer’s website. Follow the on-screen instructions to complete the installation​.

2. Installing an Internal PCI Fax Modem

1. Prepare the computer: Turn off the computer and unplug it. Open the case and locate an empty PCI slot on the motherboard.
2. Install the modem: Insert the PCI modem card into the slot, ensuring it is securely in place. Close the case and reconnect the power.
3. Driver installation: Power on the computer and install the necessary drivers using the installation disc or downloaded software. Follow the setup prompts to complete the process​.

3. Configuring the Modem in Windows

After installing the hardware, you can set up your modem using Windows Fax and Scan:

1. Go to “Start” > “All Programs” > “Windows Fax and Scan.”
2. Click “New Fax” and choose “Connect to a fax modem.”
3. Follow the prompts to set up and test your modem connection

Types of Fax Modems

A fax modem, short for facsimile modem, is a device used to transmit and receive fax documents over a telephone line. It essentially serves as the intermediary between a computer or fax machine and the telephone network, converting digital data into analog signals that can be transmitted over standard phone lines, and vice versa.

There are primarily two types of fax modems:

• Internal Fax Modems: These are installed inside a computer or fax machine. They typically connect to the computer’s motherboard via an expansion slot or internally via USB. Internal fax modems were more common in older computers but have become less prevalent with the advent of external USB modems and the integration of fax functionality into multifunction printers.
• External Fax Modems: These are standalone devices that connect to a computer or fax machine via a cable, often USB or Ethernet. External fax modems are generally more versatile as they can be easily moved between different computers or devices. They also tend to be easier to install and troubleshoot.

Fax modem for Windows 10

For Windows 10 users, the built-in software “Windows Fax and Scan” is commonly used to manage fax activities. This software allows you to send and receive faxes directly from your computer. To use it, you need a fax modem connected to a physical phone line, as VoIP lines are generally incompatible for fax transmissions​.

Setting up a fax modem on Windows 10 typically involves installing the necessary drivers, connecting the device to a phone line, and configuring the fax settings in Windows Fax and Scan. This setup allows you to send and receive faxes just like with a traditional fax machine​.
