I have this printer, scanner, fax in stand alone configuration. No computer no network, It was working fine then this week this message started appearing and the machine is frozen. tried the restart by holding stop and turning power on but no luck. Suggestions?
You can try unplugging the printer from the power and then pressing the power button 10 times while the printer is unplugged. After that, you can plug the printer into a different power source and you can try turning it on.
If the error does not clear please download and install the firmware update for your unit from Canon's website at www.usa.canon.com. Many times this will fix the issue. You would need to download and install the firmware using a computer connected via USB.
