The fusing unit can cause serious burns. 1. If you will install a lot of new parts in the fusing unit (at PM for example), then set SP 3902-014 to 1. ƒ If you do this, then the machine will reset the PM counter for the fusing unit automatically, after you turn the power on again. Do not do this if you replace the complete fusing unit. This is because the fusing unit has a new detection mechanism. 2. Turn off the main power switch. 3. Open the right door. 4. Release the lock levers [A]. 5. Fusing unit [B]
