Put the assembly 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 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.
