Canon error code 1682
Quick answer
A FINE cartridge cannot be recognized. Replace the FINE cartridge following Canon's replacement guide; if that doesn't fix it, the printer may have internal damage requiring service from an authorized Canon repair center. Unplugging erases stored faxes.
Caution: This step can be done wrong in a way that is costly or hard to undo, including voiding your warranty. Check your model's manual before proceeding.
