IMPORTANT

For high-quality printouts, when replacing the drum unit we recommend using a Canon drum unit.
Store drum units in a location away from light sources such as direct sunlight.
Storing the drum unit in a room that is cold but rapidly heated, or has other rapid temperature changes, causes water droplets (condensation) to form inside it.
Do not remove the orange protective cover until you insert the drum unit into the machine.
