Brother MFC-J855DN Remote Setup Port (COM4) Driver

The Brother MFC-J855DN 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 device, restoring a missing port, or troubleshooting remote configuration tools that cannot detect the printer.

Unlike a standard print driver, this component relates to the device’s remote setup connection. The COM4 label identifies the port assigned in Windows; your computer may assign a different COM number.

Key Features

• Remote setup communication: Supports the connection that compatible Brother utilities use to access device settings over USB.
• Device recognition: Helps Windows identify the remote setup port rather than leaving it listed as an unknown or unconfigured device.
• Legacy Windows support: Listed operating systems include Windows 10, 8.1, 7, Vista, and XP; select a package that explicitly supports your version and system architecture.
• Setup troubleshooting: Reinstalling the appropriate driver may resolve detection problems caused by missing or damaged driver files.

How to Install Brother MFC-J855DN 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 computers, note that Windows 11 is not included in the supplied compatibility list; verify support with Brother before proceeding.
2. Choose the correct package. When selecting a Brother MFC-J855DN Remote Setup Port (COM4) driver download for Windows, match the printer model and operating system. Look for the latest version compatible with your system, not simply the newest package available.
3. Download from a trusted source. Prefer Brother’s official support resources for a free download. The remote setup driver may be included in a broader driver and software package rather than offered separately.
4. Run the installer. Extract the downloaded files if necessary, launch the setup program, and follow its instructions. Connect or disconnect the USB cable only when prompted.
5. Verify the connection. Restart Windows if requested, then check Device Manager for warning icons and test detection using the compatible Brother remote setup utility. Do not force the port to COM4 unless the software specifically requires it.

Keep this driver updated when Brother provides a compatible update that addresses your issue or supports a system change. If remote setup already works reliably, review the release notes before replacing the installed driver, and avoid packages intended for a different model or Windows version.
