The Brother MFC 640CW driver allows Windows to communicate with your multifunction printer, helping applications send print jobs and use the device’s available settings. Choosing the correct Brother software package can also enable scanning features, depending on the components included and your operating system.

Key Features

• Print controls: Access options such as paper size, media type, print quality, and color settings to suit everyday documents or images.
• Scanning support: A compatible scanner driver lets supported Windows applications receive scans from the device’s flatbed or document feeder.
• Connection setup: Configure communication over USB or a supported network connection, depending on the driver package and your setup.
• Device recognition: Help Windows identify the Brother MFC 640CW correctly rather than relying on a generic printer entry that may offer fewer options.

How to Install

1. Check your Windows version. Identify whether your computer uses Windows 11, 10, 8, or 7, and check its system type where applicable. This is an older printer, so confirm that the download explicitly supports your operating system; a legacy package may not work on newer Windows versions.
2. Select the appropriate package. Choose a printer driver for printing only, or a compatible full software package if you also need scanning tools. Review any listed connection requirements before downloading.
3. Prepare the printer. Turn it on and clear any errors shown on its display. For a network installation, connect the printer and computer to the same local network. For USB installation, follow the installer’s instructions about when to attach the cable.
4. Run the installer. Open the downloaded file, approve the Windows permission prompt if requested, and follow the setup instructions. Select the correct connection method and printer when prompted.
5. Verify operation. Restart Windows if required, then print a test page from the printer settings. If you installed scanning support, try a scan in a compatible application as well.

If no compatible package is listed for your Windows version, check Brother’s compatibility guidance before attempting to install an older driver.

Common Issues and Fixes

• Install fails or stalls: Run the Brother setup as administrator, temporarily disable antivirus, and use the full driver package rather than a bare INF. Remove any partial Brother MFC 640CW entries in Devices and Printers, reboot, then reinstall.
• Device not detected: Power-cycle the MFC 640CW, connect USB directly to the PC (not a hub), and try another port. For Ethernet, confirm the printer’s IP and add it by TCP/IP port instead of relying on auto-discovery.
• Version/driver conflicts: Uninstall older Brother MFC 640CW printer/scanner drivers and Brother software first, restart, and match the package to your Windows version and 32/64-bit architecture. Avoid mixing legacy WIA/TWAIN scanner drivers with a newer full package.
