7. Holding the complete assembly by its top center, lower it into
place in the printer, locating the pegs at each end (1) into their
slots (2) in the sides of the printer cavity.
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.
