Canon printer Default Password is typically set by the manufacturer to allow initial setup and configuration. In most cases, the default username is “admin,” and the default password is either “admin,” the printer’s serial number, or left blank, depending on the model. Users are strongly advised to change the default password after setup to enhance security and prevent unauthorized access. If you cannot log in, resetting the printer to factory settings can restore the default credentials, allowing you to reconfigure your device safely.
