Pull the grey lever on the old toner cartridge
towards the front of the machine. Lift the old toner
cartridge out of the image drum unit. Dispose of it
in the plastic bag that your new cartridge came in.
Remove the new toner cartridge from its package
and gently shake it from side to side. Then peel
the white plastic tape from the bottom of the toner
cartridge.
With the smooth black surface uppermost (marked
L and R) and the grey lever on the right, insert the
toner cartridge into the image drum unit. Slide in
the left end of the cartridge first, then lower the
right end into place.
Be sure to insert the toner cartridge into the drum the
right way around.
Once in place, push the grey lever on the toner
cartridge towards the back of the machine to
secure it.
Using the cleaning wipe, gently wipe back and
forth across the full length of the LED array.
Close the top cover.
