Brother MFC-420CN USB Remote Setup Port (COM4) Driver

The Brother MFC-420CN USB Remote Setup Port (COM4) driver helps Windows recognize the USB communication interface used by Brother’s Remote Setup software to configure the MFC-420CN multifunction device. It is intended for users who need to restore remote configuration access after reinstalling Windows, reconnecting the device, or encountering a missing port in Device Manager.

Key Features

• Remote Setup communication: Supports the USB connection used by compatible Brother software to access device settings.
• Windows device recognition: Helps identify the Remote Setup interface so configuration software can communicate with the connected machine.
• Dedicated setup interface: Serves a configuration role rather than replacing the separate drivers required for printing and scanning.
• Legacy Windows support: Look for a package matching Windows 10, 8.1, 7, Vista, or XP, and verify its compatibility with your system architecture before installation.

Although this interface may be listed in the Network category, its name refers to a USB Remote Setup port. COM4 is the port assignment shown on this computer; Windows may assign a different number on another system.

How to Install Brother MFC-420CN USB Remote Setup Port (COM4) Driver

1. Check your Windows version and whether it is 32-bit or 64-bit. For Windows 10/11 systems, check compatibility carefully: Windows 11 is not included in the supported OS list provided for this device.
2. Before starting a Brother MFC-420CN USB Remote Setup Port (COM4) driver download for Windows, confirm that the package identifies the MFC-420CN and supports your operating system. Choose a trusted free download source, preferably Brother’s official support resources.
3. Download and extract the package if necessary. If it includes an installer, run it and follow the instructions, connecting the USB cable when prompted.
4. If the package requires manual installation, open Device Manager, locate the relevant Remote Setup or unrecognized interface, select Update driver, and browse to the extracted driver folder.
5. Restart Windows if requested, then check Device Manager for warnings. Open compatible Brother Remote Setup software to verify communication with the device.

Keep the driver updated when a compatible release addresses a problem you are experiencing. The latest version available for this older model may not support newer Windows releases, so verify compatibility before you install an update and retain a working installer for recovery.
