HP 4101mfp manual Service approach, Major assemblies

Service approach

Repair of the printer normally begins with a three-step process:

1Isolate the problem to the major system (the host computer, the network and/or server, or MFP major assemblies).

2Determine whether the problem is located in one of the paper-handling devices or in the product engine.

3Troubleshoot the problem using the procedures in the troubleshooting chapter of this manual. See “Troubleshooting” on page 109.

When a faulty part is identified, 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 boards (PCBs).
