Service approach
Repair of the printer normally begins by using the printer's internal diagnostics in conjunction with the
troubleshooting procedures that are described in chapter 6. When a faulty part is located, repair is
generally accomplished by assembly-level replacement of field-replaceable units (FRUs) (listed in
chapter 7). Some mechanical assemblies might be repaired at the subassembly level. Hewlett-
Packard Company does not support replacement of components on printed circuit boards.
