image drum when the print becomes faint or begins to
deteriorate.
Replacing 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.
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.
1. Press the cover release and open the printer’s top cover
fully.
WARNING! If the printer has been powered on, the fuser may
be hot. This area is clearly labeled. Do not touch.
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. Gently wipe the LED array surface with the LED lens
cleaner that came with the new toner cartridge, or wipe
with a soft tissue.
5. Close the top cover and press it down to latch it closed.
