Cold Fuser Service Check
If all the Cold Fuser Service Check items are correct, go to the “Hot Fuser Service Check” on page
Note: Toner buildup on the fuser input guide, paper separator, hot roll and backup roll causes paper jams.
When toner is partially fused to the paper it is usually caused by low fuser temperature.
Avoid handling the lamp as much as possible as it is easily broken. Be careful not to touch the glass housing with bare hands as the skin contains acids that can weaken the glass.
When making checks and handling the fuser lamp make sure you allow enough time for the fuser lamp and associated parts to cool.
