CAUTION!
The green image drum surface at the base of the Image Drum is
very delicate and light sensitive. Do not touch it and do not expose
it to normal room light for more than 5 minutes. If the drum unit

cartridge inside a black plastic bag to keep it away from light.
Never expose the drum to direct sunlight or very bright room
lighting.
