5.Put the cartridge down gently onto a piece of paper to prevent toner from marking your furniture and to avoid damaging the green drum surface.
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.
6.Remove the new cartridge from its box but leave its wrapping material in place for the moment.
7.Gently shake the new cartridge from end to end several times to loosen and distribute the toner evenly inside the cartridge.
8.Remove the wrapping material and peel off the adhesive tape from the underside of the cartridge.
