Service approach
Repair of the printer normally begins with a three-step process:
1 Isolate the problem to the major system (the host computer, the network and/or server, or
MFP major assemblies).
2 Determine whether the problem is located in one of the paper-handling devices or in the
product engine.
3 Troubleshoot 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).
