PROBLEM DESCRIPTION: The 47 Ohm socketed resistor on the fuser
safety PCB may be blowing.
CAUSE: The fuser bulb in the fuser assembly is not making good contact.
The 47 Ohm resistor on the fuser safety PCB, which acts as a fuse,
will blow to protect the rest of the fuser circuitry. Sometimes the fuser
bulb is shaken out of good contact during shipment or the fuser resistor
just fails. It does not necessarily mean that any other part on the fuser
has failed.
CURE: Make sure that the fuser bulb is securely installed. Then replace
the 47 ohm fuse/resistor on the fuser safety PCB.
If the above cure does not solve your problem, refer to the LaserWriter
Printer Technical Procedures for the general troubleshooting procedure.
