Fuser replacement
The fuser is located inside the printer just behind the four
image drum units.
Switch off the printer and allow the fuser to cool for about
10 minutes before opening the cover.
1. Press the cover release and open the printer’s top cover fully.

2. Identify the fuser handle (1) on the top of the fuser unit.
WARNING!
If the printer has recently been powered on, some fuser
components will be very hot. Handle the fuser with
extreme care, holding it only by its handle, which will
only be mildly warm to the touch. A warning label clearly
indicates the area. If in doubt, switch the printer off and
wait at least 10 minutes for the fuser to cool before
opening the printer cover.
