The Brother MFC 665CW driver helps Windows communicate with your all-in-one inkjet printer so documents and photos reach the print queue with the correct settings. When setting up the device on Windows 11, 10, 8, or 7, choose a package that matches your system and connection method; available functions can vary by driver.

Key Features

• Everyday printing controls: Adjust paper size, orientation, print quality, and color settings for documents, images, and other routine print jobs.
• USB and network setup: Configure printing through a USB connection or over a compatible local network, depending on the selected driver and installation options.
• Scanning support: A compatible scanner driver or full software package can let supported Windows applications receive scans from the MFC 665CW. A print-only driver may not include this function.
• Device-specific communication: Give Windows the information it needs to identify the printer and send jobs using the appropriate device settings.

How to Install

1. Check your Windows version. Open your PC’s system information to confirm the Windows edition and whether it uses a 32-bit or 64-bit system. Check the download’s compatibility details before choosing a driver, especially for newer Windows versions.
2. Download the appropriate package. Select a Brother MFC 665CW driver for your operating system. If you need scanning as well as printing, look for a compatible full software package or separate scanner driver.
3. Prepare the connection. Turn on the printer. For network installation, make sure the printer and computer are on the same local network. For USB installation, follow the installer’s instructions about when to connect the cable.
4. Run the installer. Open the downloaded file, approve any Windows permission prompt, and follow the setup instructions. Choose the correct connection type and select your printer when it appears.
5. Verify operation. Restart the computer if requested, then print a test page from Windows printer settings. If you installed scanning software, try a simple scan too.

If the printer is not detected, check its connection and network status before reinstalling. For this older model, confirm that the available package explicitly supports your Windows version rather than assuming every legacy installer will work.

Common Issues and Fixes

• Install fails or stalls: Disconnect the USB cable until the Brother installer prompts you, run the setup as administrator, and temporarily disable antivirus. Remove any older Brother MFC-665CW entries in Devices and Printers before retrying.
• Device not detected: For USB, try a different port/cable and avoid hubs. For wireless, connect the MFC-665CW to a 2.4 GHz network, confirm the SSID/password on the printer panel, and assign a static IP if the router changes addresses.
• Driver/version conflicts: Uninstall existing Brother software and the Windows inbox driver, restart, then install the full Brother package for your Windows version. In Printer Server Properties, delete stale MFC-665CW ports before reinstalling.
