The Canon default password for printers varies depending on the model, but it is typically "admin" or "password". However, it is recommended to change the default password to ensure better security of your network and device. To change the password, access the printer's web interface, navigate to the network or security settings and look for the option to change the password. If you are unable to find the default password for your specific model, you can consult the printer's manual or check the manufacturer's website for more information.
