Brother MFC-3100C Remote Setup Port USB (COM4) Driver

The Brother MFC-3100C Remote Setup Port USB (COM4) driver helps Windows recognize the USB-connected remote setup interface used to communicate with your Brother multifunction device. It is intended for users who need to configure the MFC-3100C through compatible Brother software or resolve a missing remote setup port after connecting the device.

Key Features

• Remote setup communication: Supports the connection between compatible Brother configuration software and the MFC-3100C’s USB remote setup interface.
• Port recognition: Helps Windows identify the remote setup connection shown as COM4. Windows may assign a different COM number depending on your system.
• Legacy Windows support: The listed operating systems are Windows 10, 8.1, 7, Vista, and XP; check the individual package details for your exact Windows edition and architecture.
• Targeted interface support: Addresses the remote setup port rather than replacing all printer, scanner, or fax software. Additional Brother components may be needed for those functions.

How to Install Brother MFC-3100C Remote Setup Port USB (COM4) Driver

1. Check your Windows version. Open your system information and confirm whether your installation is 32-bit or 64-bit. If you are comparing Windows 10/11 compatibility, note that Windows 11 is not included in the supplied supported-OS list.
2. Choose a compatible package. Before starting your Brother MFC-3100C Remote Setup Port USB (COM4) driver download for Windows, verify that the package explicitly supports your model and operating system. Select the latest version available for that combination, not simply the newest package overall.
3. Download and prepare the files. Use a trusted source for a free download, scan the file with your security software, and extract it if supplied as an archive. Follow any included instructions about when to connect the USB cable.
4. Install the driver. Run the supplied installer if available. For a driver-only package, open Device Manager, locate the relevant remote setup or unrecognized device, choose Update driver, and browse to the extracted driver folder.
5. Verify the connection. Restart Windows if prompted, reconnect the device as instructed, and check Device Manager for warning icons. Test communication using compatible Brother remote setup software.

Keep a working driver unless an update addresses a specific problem or adds needed compatibility. Before changing versions, review the package notes and retain a copy of the previous installer so you can recover if remote setup communication stops working.
