Brother MFC-J850DN Remote Setup Port (COM3) Driver

The Brother MFC-J850DN Remote Setup Port (COM3) driver helps Windows recognize the communication interface used by Brother’s Remote Setup software to access supported printer settings. It is intended for users setting up the Brother MFC-J850DN multifunction printer or troubleshooting a missing remote setup port, rather than replacing the main printer driver.

Key Features

• Remote setup communication: Supports the connection between compatible Brother configuration software and the printer’s remote setup interface.
• Windows device recognition: Helps Windows identify the Remote Setup Port entry so the appropriate software can communicate with it.
• Legacy Windows support: Listed operating systems include Windows 10, 8.1, 7, Vista, and XP. Select a package that explicitly supports your Windows version and system architecture.
• Configuration support: Works alongside the relevant Brother software components; printing and scanning may require separate drivers or a full software package.

How to Install Brother MFC-J850DN Remote Setup Port (COM3) Driver

1. Check your Windows version and system type. Confirm whether your computer uses a 32-bit or 64-bit edition before choosing a Brother MFC-J850DN Remote Setup Port (COM3) driver download for Windows. If comparing Windows 10/11 compatibility, note that Windows 11 is not included in this device’s listed supported systems.
2. Choose a verified package. Look for the latest version that explicitly matches the MFC-J850DN and your operating system. Prefer an official Brother free download when available, and avoid installers that bundle unrelated utilities.
3. Prepare the printer and computer. Close Brother applications and follow the package instructions about when to connect or power on the printer. If you are replacing an existing driver, check whether removal is required first.
4. Install the driver. Run the downloaded installer and follow its prompts. If the package contains only driver files, use Device Manager’s Update driver option and browse to the extracted folder.
5. Verify operation. Restart Windows if prompted, then check Device Manager for warning icons and test the compatible Brother Remote Setup utility. The assigned COM number can vary between computers, so a different port number does not necessarily indicate a problem.

Keep the driver updated when Brother provides a compatible release that addresses your needs. Before you update, review the supported systems and installation notes; a newer package is only useful if it supports your printer and Windows environment.
