HP LaserJet 9000 Service Manual - Page 30

Service approach Repair of the printer normally begins with a three-step process: z isolate the problem to the major system (the host computer, the network and/or server, or the printer system) z determine whether the problem is located in one of the paper-handling devices or in the printer engine z troubleshoot the problem using the procedures in chapter 7 When a faulty part is located, repair is usually accomplished by assembly-level replacement of field replaceable units (FRUs). Some mechanical assemblies can be repaired at the subassembly level. Hewlett-Packard does not support replacement of components on the printed circuit assemblies.
