Canon Service: Tool V6000 Hot _best_

: This is a special, low-level operational state built into Canon printers. It allows access to advanced diagnostics, configuration, and maintenance functions that are not available during normal use. A printer is put into Service Mode by pressing a specific combination of physical buttons on the device, often involving the "Power" and "Resume/Stop" buttons, without any software involved. This mode is a built-in feature, not a third-party creation.
