Brother MFC-J3520 Remote Setup Port (COM3) Driver

The Brother MFC-J3520 Remote Setup Port (COM3) driver helps Windows recognize the USB-connected remote setup interface used to configure your Brother MFC-J3520 multifunction printer. It is intended for users who need Brother’s Remote Setup software to communicate with the device, particularly after reinstalling Windows or encountering an unrecognized port in Device Manager.

Key Features

• Remote setup communication: Supports the connection between the printer’s remote setup interface and compatible Brother configuration software.
• USB interface recognition: Helps Windows identify the remote setup port, which may appear as COM3 in Device Manager. The assigned COM number can vary by computer.
• Legacy Windows support: Listed operating systems include Windows 10, 8.1, 7, Vista, and XP. Choose a package that explicitly supports your Windows version and architecture.
• Device-specific configuration support: Addresses the remote setup interface rather than replacing the separate drivers needed for printing or scanning.

How to Install Brother MFC-J3520 Remote Setup Port (COM3) 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 compatibility, note that Windows 11 is not included in the supplied support list; verify compatibility with Brother before proceeding.
2. Select the correct package. For a Brother MFC-J3520 Remote Setup Port (COM3) driver download for Windows, use an official Brother source and match the package to the MFC-J3520 and your operating system. Look for the latest version available for that combination, not simply the newest package overall.
3. Prepare the USB connection. Turn on the printer and follow the installer’s connection instructions. If prompted, leave the USB cable disconnected until setup asks you to connect it.
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 supplied folder.
5. Verify operation. Restart Windows if requested, then check Device Manager for warning icons. Open compatible Brother Remote Setup software to confirm that it can communicate with the printer.

Keep this driver updated when Brother provides a compatible update that addresses connection issues or improves reliability. Official driver packages are generally available as a free download; avoid third-party tools that require payment to unlock installation. If your current setup works reliably, review the release notes before making changes.
