Fuser service check
When toner is partially fused to the paper, it is usually caused by low
fuser temperature.
Warning: 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 skin contains acids that can weaken
the glass.
The line voltage to the printer must be within the following limits:
•
100 V ac–127 V ac for the low voltage model printer
•
200 V ac–240 V ac for the high voltage model printer
Turn the printer off and wait a few minutes for the fuser lamp to cool.
Turn the machine on and observe the lamp turning on during POST.
