Brother MFC-J3720 Remote Setup Port (COM4) Driver

The Brother MFC-J3720 Remote Setup Port (COM4) driver helps Windows recognize the USB-connected setup interface used by Brother software to communicate with your multifunction printer. It is intended for users setting up the MFC-J3720, restoring its remote configuration connection, or troubleshooting an unrecognized port in Device Manager.

Key Features

• Remote setup communication: Supports the connection between compatible Brother Remote Setup software and the printer’s configuration interface.
• USB interface recognition: Helps Windows identify the remote setup port correctly rather than leaving it listed as an unknown device.
• Legacy Windows support: Intended for supported installations of Windows 10, 8.1, 7, Vista, and XP, with package compatibility depending on the operating system and architecture.
• Configuration troubleshooting: Reinstalling the appropriate driver may help resolve missing-port or communication issues. This component is separate from the printer’s full printing and scanning software.

How to Install Brother MFC-J3720 Remote Setup Port (COM4) Driver

1. Check your Windows version. Confirm your operating system and whether it is 32-bit or 64-bit. For Windows 10/11 systems, note that Windows 10 is listed as supported here; Windows 11 compatibility must be verified separately with Brother.
2. Choose a compatible package. Before starting your Brother MFC-J3720 Remote Setup Port (COM4) driver download for Windows, check that the package explicitly supports your printer model and operating system. Select the latest version available for that combination.
3. Download and prepare the installer. Use a trusted Brother-provided package when available. A free download should not require purchasing a third-party driver updater. Extract the files if they arrive in a compressed archive.
4. Install the driver. Run the supplied setup program and follow its instructions, connecting the printer by USB when prompted. If only driver files are provided, use Device Manager’s Update Driver option and browse to the extracted folder.
5. Verify the connection. Restart Windows if requested, then check Device Manager for the remote setup interface and test communication using compatible Brother software. Windows may assign a COM number other than COM4; this alone does not indicate a problem.

Keep the driver updated when Brother provides a compatible release that addresses your issue or improves reliability. Before you update, confirm OS support and retain the working installer if possible. If remote setup still fails, also check the USB cable, connection, and Brother software installation.
