The Brother FAX 4100 driver allows Windows to communicate with your Brother printer and send documents to its print queue. Installing a suitable driver helps you access printing preferences and resolve problems caused by a missing or incorrectly configured printer connection.

Key Features

• Windows printing support: Provides the software connection needed to send print jobs from compatible applications to the Brother FAX 4100.
• Print preference controls: Offers access to available settings such as paper size, orientation, and copy count, depending on the driver installed.
• Printer identification: Helps Windows recognize the device as the correct printer rather than leaving it listed as an unknown device.
• Print queue integration: Works with Windows printer management tools so you can view pending documents and cancel unwanted jobs.

How to Install

1. Check your Windows version. Before choosing a download, confirm whether you use Windows 11, 10, 8, or 7, along with your system architecture. Driver availability and installation methods can differ, particularly for older hardware.

1. Select a compatible driver. Review the package details to make sure they cover the Brother FAX 4100 and your operating system. If a dedicated package is unavailable, check Brother’s guidance for a supported Windows built-in driver or another recommended installation method. Do not assume an older installer will work on a newer system.

1. Prepare the printer. Turn on the device, load paper, and check for any error messages. For a local connection, follow the driver instructions on when to attach the printer cable; some installers require you to wait until prompted.

1. Install and configure. Extract the downloaded files if necessary, then run the setup program and follow its prompts. If you are using a built-in driver, open Windows printer settings, choose the option to add a printer, and select the appropriate driver and connection port.

1. Print a test page. Once installation is complete, open the printer’s properties and send a Windows test page. If nothing prints, check the cable, selected port, and print queue before reinstalling. Set the Brother FAX 4100 as your default printer if it will handle most of your documents.

A printer driver enables computer printing; it does not automatically add PC faxing or other functions that the selected driver and connection do not support.

Common Issues and Fixes

• Install fails or rolls back: The FAX-4100 uses a legacy Brother driver. Run the installer as Administrator, try Windows Compatibility Mode for the listed OS, and connect/power on the fax only when prompted. If setup still fails, extract the package and add the driver manually via Devices and Printers.
• Device not detected: Connect the FAX-4100 directly to a USB port, not a hub/dock. Try a known-good cable, power-cycle the fax, and check Device Manager for unknown devices. Remove failed Brother entries, reboot, then reconnect.
• Version conflicts or duplicate fax entries: Uninstall older Brother FAX software and remove stale FAX-4100 entries in Print Management and Devices and Printers. Restart the print spooler, then install one matching 32/64-bit driver package.
