Brother MFC-670CD Remote Setup Port (COM4) Driver

The Brother MFC-670CD Remote Setup Port (COM4) driver helps Windows recognize the communication interface used by Brother’s Remote Setup software to access compatible device settings. It is intended for users setting up an MFC-670CD or troubleshooting a missing remote setup connection, rather than adding camera or imaging features.

Key Features

• Remote setup communication: Supports the connection between the device’s remote setup interface and compatible Brother configuration software.
• Windows device recognition: Helps Windows identify the remote setup port correctly instead of leaving it listed as an unknown device.
• Legacy Windows support: Listed operating systems include Windows 10, 8.1, 7, Vista, and XP; check the individual package for your Windows version and architecture.
• Connection troubleshooting: Reinstalling the appropriate driver may help resolve driver-related recognition errors. The COM4 label identifies the assigned port, which can differ between computers.

How to Install Brother MFC-670CD Remote Setup Port (COM4) Driver

1. Check your system. Confirm your Windows version and whether it is 32-bit or 64-bit. If you are comparing Windows 10/11 options, note that Windows 11 is not included in the listed supported systems; do not assume compatibility.
2. Select the correct package. Before starting your Brother MFC-670CD Remote Setup Port (COM4) driver download for Windows, verify that the package explicitly supports your device and operating system. Choose the latest version compatible with your setup.
3. Download safely. Use a trusted source for a free download, and review any included installation instructions. Avoid unrelated driver bundles or packages that do not identify the supported model.
4. Install the driver. Close Brother utilities, extract the downloaded files if necessary, and run the installer. Follow its prompts, including any instructions about when to connect or disconnect the device.
5. Verify the connection. Restart Windows if requested, then check Device Manager for warning icons. Open the compatible Brother Remote Setup utility and confirm that it can communicate with the device. If a different COM number appears, check the utility’s connection settings.

Keep the driver updated when a compatible update addresses a connection issue or improves support for your system. Before replacing a working installation, review the package’s compatibility information and keep a copy of the previous installer in case you need to restore it.

Common Issues and Fixes

• Install fails or stalls: Disconnect the USB cable, run the Brother MFC-670CD installer as administrator, then reconnect the printer only when prompted. Remove any old Brother MFC-670CD entries under Device Manager > Ports (COM & LPT) before retrying.
• COM4 port not detected: Confirm the printer is powered on and USB-connected. In Device Manager, enable “Show hidden devices” and check Ports for the Remote Setup Port. If Windows assigns another COM number, reassign it to COM4 or update the port selection in Brother Remote Setup.
• Version conflicts: Uninstall older Brother MFC-670CD software and leftover Remote Setup Port drivers, restart Windows, then install the latest full driver package for your Windows version. Avoid installing a new port driver over an existing one.
