Service approach Printer repair normally begins by using the printer internal diagnostics and the following two-step process: 1. Isolate the problem to the major system (for example, the network or server, or the printer). 2. Troubleshoot the problem by using the procedures in chapter 6. After a faulty part is located, the printer can usually be repaired at the assembly level by replacing fieldreplaceable units (FRUs). Some mechanical assemblies might need to be repaired at the subassembly level. Hewlett-Packard Company does not support replacement of components on the printed circuit assembles.
