Product Information
Service Approach
Service Approach
Repair of the printer normally begins with use of the printer’s
internal diagnostics in conjunction with the troubleshooting
procedures in Chapter 7. Once a faulty part is located, repair is
e
accomplished generally by assembly-level replacement of Field
Replaceable Units (FRUS). Some mechanical parts maybe
repaired at the sub-assembly. PCA component replacement is not
supported by HP. Part numbers for all FRUS are located in
Chapter 8 of this manual.
Exchange Program
HP offers remanufactured assemblies for some selected parts.
These are identified in Chapter 8 and can be ordered through HP’s
Parts Direct Ordering, or Parts Center Europe (PCE).
Ordering Parts
Field replaceable part numbers are found in Chapter 8 of this
manual. Replacement parts may be ordered from HP’s Parts Direct
Ordering, or Parts Center Europe (PCE). Adresses and phone
numbers for both organizations are also found in Chapter 8.
Ordering Consumables
Consumables may be ordered directly from Hewlett-Packard. The
phone numbers for ordering consumables are found in Chapter 8.
