fuser temperature.

WARNING:

ARNING: Avoid handling the lamp as much as possible as it is

easily broken. Be careful not to touch the glass housing with bare

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

27 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.

POST.

You can see the lamp with the left side cover and fuser wire cover
removed.
