The products described in this manual (HP LaserJet Enterprise MFP M806 / M830) use a field repair strategy. Defective parts are diagnosed and replaced at the Field Replaceable Unit (FRU) assembly level. Repair normally begins by using the HP LaserJet Enterprise MFP M806 / M830 internal diagnostics and the following two-step process:
1. Isolate the problem to the major system (for example, the network or server, or the product).
2. Troubleshoot the problem by using the procedures in the troubleshooting manual.
After you locate a faulty part, the product can usually be repaired at the assembly level by replacing FRUs. Some mechanical assemblies might need to be repaired at the subassembly level. HewlettPackard Company does not support replacement of components on the printed circuit assembles.
