correctly, remove any other attached paper handling options.
Observe all necessary ESD precautions when removing and
handling the controller board, engine board or any of the installed
option cards or assemblies.
Service Tip: When removing the LVPS from the printer observe the
following:
1. The LVPS uses a self docking connector that mates with
another connector mounted on the left side frame assembly.
Some force may be required to pull the LVPS loose from the
connector.
2. Gently remove the LVPS supply using caution not to damage
the printed circuit board. Pull the LVPS out far enough to reach
the fuser lamp cable.
3. The fuser lamp cable uses a locking type of connector system.
Unlock the fuser lamp cable connector, disconnect the cable
and remove the LVPS from the printer.
Note: If the LVPS is blowing fuses, remove the LVPS from the
printer. Check the metal LVPS shield for signs of damage that
causes the shield to touch components on the LVPS board
assembly.
