Brother MFC-J870DW Remote Setup Port (COM4) Driver

The Brother MFC-J870DW Remote Setup Port (COM4) driver helps Windows recognize the USB-connected remote setup interface used by Brother software to communicate with your multifunction printer. It is intended for users setting up the MFC-J870DW or troubleshooting an unrecognized remote setup port, rather than replacing the printer’s separate printing and scanning drivers.

Key Features

• Remote setup communication: Supports the connection between compatible Brother setup software and the device’s configuration interface.
• USB port recognition: Helps Windows identify the remote setup component instead of leaving it listed as an unknown device.
• Legacy Windows support: Listed operating systems include Windows 10, 8.1, 7, Vista, and XP. Choose a package that explicitly supports your Windows edition and system architecture.
• Brother software integration: Works alongside the appropriate Brother utilities and other device drivers needed for your printer’s functions.

How to Install Brother MFC-J870DW Remote Setup Port (COM4) Driver

1. Check your Windows version and system type. Confirm whether your installation is 32-bit or 64-bit before choosing a package. For Windows 10/11 systems, check compatibility carefully: Windows 10 is listed here, but Windows 11 support is not confirmed.
2. Select a compatible package. For a Brother MFC-J870DW Remote Setup Port (COM4) driver download for Windows, use an official Brother source where available. Look for the latest version that supports your operating system; a free download should not require purchasing a third-party driver updater.
3. Prepare the USB connection. Close Brother utilities and follow the installer’s instructions about when to connect the printer. Avoid connecting or disconnecting the USB cable during installation unless prompted.
4. Install the driver. 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. Verify detection. Restart Windows if requested, then check Device Manager for warning icons and test communication through the compatible Brother remote setup utility. The COM port number may differ from COM4 because Windows assigns it locally.

Keep the driver updated when Brother provides a compatible release or when you need to resolve a connection problem. Before an update, review the package’s supported systems and installation notes; a newer driver intended for another Windows version is not necessarily suitable for your computer.
