Brother MFC-J3520 Remote Setup Port (COM4) Driver

The Brother MFC-J3520 Remote Setup Port (COM4) driver helps Windows recognize the USB-connected remote setup interface used by Brother software to communicate with the multifunction printer.

Key Features

• Remote setup communication: Supports the connection between compatible Brother configuration software and the MFC-J3520’s remote setup interface.
• USB device recognition: Helps Windows identify the remote setup port correctly rather than leaving it listed as an unknown device.
• COM port identification: The device name includes COM4, although Windows may assign a different port number depending on your computer’s configuration.
• Legacy Windows options: Listed operating systems include Windows 10, 8.1, 7, Vista, and XP. Select a package that matches your Windows version and system architecture.

How to Install Brother MFC-J3520 Remote Setup Port (COM4) Driver

1. Check your Windows version. Confirm your operating system and whether it is 32-bit or 64-bit. If you are comparing Windows 10/11 support, note that Windows 11 is not included in the listed compatibility information; verify support with Brother before installing.
2. Choose the appropriate package. For a Brother MFC-J3520 Remote Setup Port (COM4) driver download for Windows, look for a Brother-issued package that explicitly supports your model and operating system. Choose the latest version compatible with your setup, not simply the newest available package.
3. Download and prepare. Use a trusted source offering a free download of the original driver package. Save your work, close Brother utilities, and follow any instructions about when to connect the USB cable.
4. Install the software. Run the downloaded installer and follow its prompts. If the download contains only extracted driver files, use Device Manager’s Update driver option and browse to the extracted folder.
5. Confirm the connection. Restart Windows if requested, then check Device Manager for the remote setup interface without a warning icon. Open compatible Brother Remote Setup software to test communication. This port driver alone does not replace the printer and scanner drivers.

Keep the driver updated when Brother provides a compatible release or when troubleshooting a connection problem. Before you update a working installation, review the package’s supported systems and instructions to avoid installing an unsuitable driver.
