Syringe
4. Fill the syringe with 10ml of oil and inject it
into the fusing unit just inside the right side of
the unit between the cover and the blade
assy. Repeat with 10ml more. (Only use a
total of 20ml of oil.)
•
Only inject the oil into the space between
the cover and blade assy, not on the
blade, not over the upper roller, not over
the front and rear gear areas.
•
Be sure to inject the oil evenly.
•
Let nothing (dust, lint, hair, etc.) fall into
the Fusing Unit to contaminate it.
•
If setting up the copier at the workshop,
do not fill the fuser oil bottle until the
copier is moved to the user’s premises. In
order to make test copies at the
workshop, inject oil into the fuser as
described in step 4 above. 30ml of oil
makes about 20 copies. Inject more oil as
needed for testing purposes.
5. Remove the cap of the fuser oil bottle. Attach
the spout to the oil can and pour the oil into
the fuser oil bottle. Recap the fuser oil bottle.

tube from the Oil Pump Assy.
NOTES
•
Hold the valve when pulling the tube off or
the valve will come off with the tube.
•
Before pulling the tube and drawing the
oil, place a paper towel underneath the
pump section to catch any priming oil
leaking from the pump.
7. Insert the syringe into the tube and draw
about 5ml of oil from it.
8. Attach the rubber tube from the accessories
box to the syringe.

10.Remove the tube and syringe, and plug back
in the lower tube of the Oil Pump Assy.
Do not turn any of the knobs, gears or
rollers of the Fusing Unit when the oil tank
is empty. The pump is primed with oil at
the factory. If anything is turned in the unit
when the tank is empty, the pump will lose
its priming oil and may not be able to pump
afterwards.
