HP 8000dn Service Manual - Page 52

Service Approach Repair of the printer normally begins with a three-step process: Step 1: Isolate the problem to the major system, i.e. the host computer, the network and/or server, or the printer system. Step 2: Determine if the problem is located in the accessories or in the printer engine. Step 3: Troubleshoot the problem using the procedures in Chapter 7. Once a faulty part is located, repair is usually accomplished by assembly level replacement of Field Replaceable Units (FRUs). Some mechanical assemblies may be repaired at the subassembly level. Replacement of components on the printed circuit assemblies is not supported by Hewlett-Packard. Ordering Parts Field replaceable part numbers are listed in Chapter 8 of this manual. Replacement parts may be ordered from HP's Support Materials Organization (SMO), or Support Materials Europe (SME).
