CAUTION!
The green image drum surface at the base of the ID unit 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 needs
to be out of the printer for longer than this, please wrap the
cartridge inside a black plastic bag to keep it away from light.
Never expose the drum to direct sunlight or very bright room
lighting.
NOTE
Follow instructions that come with the new image drum for additional
information such as the removal of packaging material etc.
