Service approach

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

z isolate the problem to the major system (the host computer, the network and/or server, or the

printer system)

z determine whether the problem is located in one of the paper-handling devices or in the printer

engine

z troubleshoot the problem using the procedures in chapter 7

When a faulty part is located, 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 assemblies.

Parts and supplies

The following information helps you locate parts and assistance.

Ordering information

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

"Consumables, supplies, accessories, FRUs, and documentation" in chapter 8 of this manual contains information about accessories that are specifically designed for this printer. Order accessories from HPS.

Exchange program

Hewlett-Packard offers remanufactured assemblies for some parts. These are identified in "Illustrations and parts lists" in chapter 8, and can be ordered through HPS.

Consumables

The printer has two consumables: the print cartridge and the preventive maintenance kit. The stapler/stacker and the 8-bin mailbox have one consumable: the staple cartridge. These are identified in "Illustrations and parts lists" in chapter 8, and can be ordered through HPS.
