3. Lift each of the image drum units out of the printer.
Place them on a flat surface in a safe place away from
direct sources of heat and light.
CAUTION!
The green surface at the base of each image drum is
very delicate and light sensitive.
• Do not touch the green surface.
• Never expose the drum to direct sunlight or to
very bright room lighting.
• Do not expose it to normal room light for more
than 5 minutes.
• If the image drum must be out of the printer for
longer than 5 minutes, place the image drum
inside a black plastic bag or carefully place it in
a drawer or cabinet to keep it away from light.
