Service approach Repair of the printer normally begins with use of the printer’s internal diagnostics in conjunction with the troubleshooting procedures in chapter 7. When a faulty part is located, repair is generally accomplished by assembly-level replacement of field-replaceable units (FRUs). Some mechanical assemblies might be repaired at the subassembly level. Hewlett-Packard does not support replacement of components on printed circuit boards. Parts and supplies Ordering information Chapter 8 of this manual contains FRU and accessory part numbers. Replacement parts can be ordered from the HP Customer Services and Support Organization.
