Holding it by its handles, lift the image drum assembly, complete with
toner cartridges, up and out of the printer.
3. Put the assembly down gently on 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. 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.
