Service approach

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

l Isolate the problem to the major system (the host computer, the network and/or server, or the

printer system).

l Determine whether the problem is located in one of the paper-handling devices or in the printer

engine.

l Troubleshoot the problem using the procedures in chapter 7.

Once a faulty part is located, repair is usually accomplished by assembly level replacement of field
replaceable units (FRUs). Some mechanical assemblies may be repaired at the subassembly level.
Replacement of components on the printed circuit assemblies is not supported by Hewlett-Packard.

Parts and supplies

Ordering information

"Ordering parts" in chapter 8 of this manual contains FRU and replacement part numbers.
Replacement parts can be ordered from the HP Customer Services and Support Organization
(CSSO).

"Consumables, supplies, accessories, FRUs, and documentation" in chapter 8 of this manual
contains accessories specifica lly des ign e d for this printer. Order accessories from CSSO.
