and place it on the piece of paper alongside the old ID unit.
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.
7.Remove the protective sheets from the image drum unit. Keep it the same way round as the old unit. Pack the old ID unit inside the packaging material for disposal.
