2. Holding it by its top centre, lift the used image drum and toner cartridge, out of
the printer.
3. 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.
4. With the colored toner release lever to the right, pull the lever towards you. This
will release the bond between the toner cartridge and the image drum unit.
5. Lift the right-hand end of the toner cartridge and then draw the cartridge to the
right to release the left-hand end, and withdraw the toner cartridge out of the
image drum cartridge. Place the cartridge on a piece of paper to avoid marking
your furniture.
6. Take the new image drum cartridge out of its packaging and place it on the piece
of paper where the old cartridge was placed. Keep it the same way round as the
old unit. Pack the old cartridge inside the packaging material for disposal.
7. Place the toner cartridge onto the new image drum cartridge. Push the left end in
first, and then lower the right end in.
8. Push the colored release lever away from you to lock the toner cartridge onto the
new image drum unit and release toner into it.
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.
Note
Follow instructions that come with the new image drum for additional
information such as the removal of packaging material etc.
