Brother MFC-9970CDW Remote Setup Port (COM3) Driver

The Brother MFC-9970CDW Remote Setup Port (COM3) driver helps Windows recognize the communication interface used by Brother’s Remote Setup software to configure the multifunction printer. It is relevant if you need remote configuration features or Windows shows a missing driver for this port; despite its Camera category listing, this entry is not a webcam driver.

Key Features

• Remote setup communication: Supports the connection between compatible Brother configuration software and the MFC-9970CDW’s remote setup interface.
• Device recognition: Helps Windows identify the Remote Setup Port rather than leave it listed as an unknown or improperly configured device.
• Legacy Windows support: Listed operating systems include Windows 10, 8.1, 7, Vista, and XP. Select a package that explicitly supports your Windows version and architecture.
• Configuration support: Works alongside the appropriate Brother software; this port driver alone does not replace the complete printing and scanning software package.

How to Install Brother MFC-9970CDW Remote Setup Port (COM3) Driver

1. Check your Windows version. Confirm whether your system is 32-bit or 64-bit. For Windows 10/11 systems, check compatibility carefully: Windows 10 is listed here, but Windows 11 support is not confirmed.
2. Choose the correct package. When selecting a Brother MFC-9970CDW Remote Setup Port (COM3) driver download for Windows, match the printer model, operating system, and architecture. Prefer an official Brother package offered as a free download.
3. Prepare the device. Turn on the printer and close any open Brother configuration tools. Follow the package instructions about when to connect the USB cable, if applicable.
4. Run the installer. Extract the downloaded archive if necessary, then install the software using the included setup program. Approve administrator permissions when prompted and restart Windows if requested.
5. Verify the installation. Open Device Manager and check that the remote setup interface has no warning icon. Test the compatible Remote Setup utility. Windows may assign a COM number other than COM3, so a different number alone does not indicate a problem.

Keep the driver updated by checking for the latest version compatible with your operating system, especially after a Windows update or if remote configuration stops working. Use verified Brother packages, review their compatibility notes, and avoid replacing a working driver with an unrelated printer or camera driver.

Common Issues and Fixes

• Install fails or stalls: Disconnect the MFC-9970CDW, uninstall older Brother MFL-Pro/Remote Setup software and drivers, reboot, then run the correct full driver package as administrator. Reconnect only when the installer prompts.
• Device/COM port not detected: In Device Manager, check Ports for “Brother MFC-9970CDW Remote Setup Port (COM3).” If missing, reinstall the full driver; if COM3 is in use, assign a free COM port and select it in Remote Setup.
• Version conflicts: Mixed old Remote Setup utility/driver versions can prevent connection. Remove all Brother MFC-9970CDW software, install the matching full package from Brother support, and reboot before opening Remote Setup.
