Service approach Printer repair normally begins by using the printer’s internal diagnostics and the three-step process below. Step 1 Isolate the problem to the major system (for example, the host computer, the network 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, the printer can usually be repaired at the assembly level by replacing field replaceable units (FRUs). Some mechanical assemblies might need to be repaired at the subassembly level.
Hewlett-Packard does not support replacement of components on the printer circuit assembles. 40 Service approach C7085-90921
