Introduction
Repair normally begins with the use of printer internal diagnostics in
conjunction with the troubleshooting procedures in chapter 7.
When repairing an HP Color LaserJet 8550 MFP printer, first isolate
the location of the problem. Usually, simply sending a print job to the
printer from a computer is sufficient to determine whether or not the
print engine is involved. If it is not, see the service manual specific to
the HP Color LaserJet 8550 MFP printer.
Once a faulty part is located, repair is generally accomplished by
assembly-level replacement of the field-replaceable units. Some
mechanical assemblies can be repaired at the subassembly level.
