When the drum reaches 90% of its life, a CHANGE DRUM
message is displayed in the operator panel LCD. Change the
image drum when the print becomes faint or begins to
deteriorate.
R EPLACING THE IMAGE DRUM
It is recommended that you change the toner cartridge
and clean the LED array at the same time as you change
the image drum.
1. Press the cover release and open the printer’s top cover
fully.
2. Remove the used image drum and toner cartridge.
3. Follow the installation instructions on or inside the box
containing the new image drum to install the new image
drum.
4. Follow the installation instructions on or inside the box
containing the new toner cartridge to install the new toner
cartridge.
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. Always hold the image
drum unit by the ends or from the top.
WARNING!
If the printer has been powered on, the fuser may be
hot. This area is clearly labelled. Do not touch.
