Step 3: Wipe the Registry (Critical)

Press Win + R, type regedit, and press Enter.
Backup your registry: File → Export → Save as "Backup.reg".
Delete the following keys if they exist:
- HKEY_LOCAL_MACHINE\SOFTWARE\Canon\

Understanding the "Port Monitor"

To understand the fix, one must understand the problem. A "Port Monitor" is a piece of software that acts as a bridge between the computer's operating system and the physical port (USB or Network) where the printer is connected. Canon’s "MF Port Monitor" is specifically designed to handle the complex data flows of their multi-function devices (printer, scanner, fax).

When the installation fails, it is usually because the operating system is blocking the attempt to replace or modify this bridge, deeming it a security risk or a file conflict.
