regulations.
CAUTION!
The green image drum surface at the base of the cartridge 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.
