Brother MFC-640CW USB Printer Driver

The Brother MFC-640CW USB Printer driver enables Windows to communicate with your Brother multifunction printer over a USB connection. It is needed when setting up the device on a computer, restoring printing after a system change, or troubleshooting a printer that Windows does not recognize.

Key Features

• USB printing support: Allows Windows applications to send print jobs to the connected Brother MFC-640CW.
• Print preferences: Provides access to settings such as paper size, orientation, and print quality, depending on the driver package.
• Windows compatibility: Choose a package intended for Windows 10, 8.1, 7, Vista, or XP, matching your system’s architecture where applicable.
• Multifunction setup options: Some packages may include additional Brother utilities or scanner support. Check the package description, as a printer-only driver may not enable every function.

How to Install Brother MFC-640CW USB Printer Driver

1. Check your Windows version. Confirm your operating system and whether it is 32-bit or 64-bit in your system information. For Windows 10/11 systems, check compatibility carefully: Windows 10 is listed for this device, but Windows 11 support is not confirmed here.
2. Select the appropriate package. Before starting your Brother MFC-640CW USB Printer driver download for Windows, verify the model name, supported operating system, and included components. Choose the latest version compatible with your setup, rather than assuming the newest package supports every Windows release.
3. Download and prepare. Obtain the driver as a free download from a trusted source, preferably Brother’s official support resources. Turn on the printer, but leave the USB cable disconnected if the installer instructs you to connect it later.
4. Install the driver. Run the downloaded installer, approve any required administrator prompt, and follow the on-screen instructions. Connect the USB cable when requested. If no installer is included, follow the package’s manual installation instructions.
5. Verify operation. Restart Windows if prompted, then open your printer settings and print a test page. If printing fails, check the USB connection and confirm that the correct printer is selected.

Keep your driver updated when a compatible update addresses a printing problem or supports a change to your system. Check the release notes before replacing a working driver, and avoid installing packages intended for a different Brother model or Windows version.

Common Issues and Fixes

• Install fails or stalls: Run the Brother MFC-640CW setup as administrator, temporarily disable antivirus, and remove any previous Brother printer software before retrying. If needed, use Windows compatibility mode for older setup packages.
• Device not detected over USB: Power on the MFC-640CW, connect it directly to the PC instead of a hub, try another USB port/cable, then check Device Manager for unknown USB devices and reinstall the driver.
• Driver/version conflicts: Uninstall old MFC-640CW or generic Brother printer entries in Programs and Features and Print Management, delete stale printer ports, reboot, then install the current full driver package.
