4.14.1 FUSING UNIT
• Turn OFF the main power switch (SW1) and wait until the fusing unit cools down
before beginning any of the procedures in this section. The fusing unit can cause
serious burns.
• Do not touch the surface of the sleeve belt, when replacing the fusing unit.
• Basically, the entire fusing unit must be replaced when SC544-00 or SC554-00 occurs.
• In some cases, the fusing unit need not be replaced if SC544-00 or SC554-00 occurs.
See “Actions When SC554-00 Occurs” for these cases.
The fusing unit features the new unit detection function, so it is not necessary to reset the PM
counter manually when replacing the fusing unit and dust filter together.
1. Release the left and right lock levers, then pull out the fusing unit [A].
