Repair of the printer normally begins with the use of the printer’s internal diagnostics in
conjunction with the troubleshooting procedures that are described in chapter 7. When a faulty
part is located, repair is generally accomplished by assembly-level replacement of fieldreplaceable units (FRUs) (listed in chapter 8). Some mechanical assemblies might be repaired at
the subassembly level. Hewlett-Packard does not support replacement of components on printed
circuit boards.

HP PartnerCare
You can use the following information to contact HP PartnerCare:
The print cartridge is designed to simplify replacement of the major consumable parts. The print
cartridge contains the printing drum and a supply of toner.
At five-percent page coverage, a print cartridge prints approximately 12,000 pages (for the
HP LaserJet 4200) or 18,000 pages (for the HP LaserJet 4300). A print cartridge might print
fewer pages if it is routinely used to print with dense ink coverage, or print more pages when it is
routinely used to print pages with less ink coverage (such as short memos). If EconoMode or
small media is always used, however, the toner supply might outlast the mechanical parts in the
print cartridge.
Refilled print cartridges
While Hewlett-Packard does not prohibit the use of refilled print cartridges during the warranty
period or while the printer is under a maintenance contract. However, the use of refilled
cartridges is not recommended for the following reasons:
●Repairs resulting from the use of refilled print cartridges are not covered under
Hewlett-Packard warranty or maintenance contracts.
●Hewlett-Packard has no control or process to ensure that a refilled print cartridge
functions at the same high level of reliability as a new HP LaserJet print cartridge.
Hewlett-Packard also cannot predict the long-term reliabi li ty effect on the printer
from using the differing toner formulations that are found in refilled cartridges.
●The print quality of HP LaserJet print cartridges influences the customer’s
perception of the printer. Hewlett-Pac kard has no control over the actual print quality
of a refilled print cartridge.
Recycling print cartridges
In many countries/regions this product’s printing supplies (for example, the print cartridge, the
drum, and the fuser) can be returned to HP through the HP printing supplies returns and
recycling program. this program is an easy-to-use free take-back program and is available in
more than 48 countries/regions. Multi-lingual program information and instructions are included
in every new HP LaserJet print cartridge and supplies package.
Since 1990, the HP printing supplies returns and recycling program has collected more than 47
million used LaserJet print cartridges that otherwise would have ended up in the world’ landfills.
Print cartridges and supplies are collected by HP’s resource and recovery partners. After a
thorough inspection, selected parts are reclaimed for use in new print cartridges. The remaining
materials are separated and converted into raw materials for use by other industries to make a
variety of products.
Returns
●U.S. returns
For a more environmentally responsible return of used print cartridges and supplies,
HP encourages the use of bulk returns. Bundle two or more print cartridges together
and use the single, prepaid, preaddress United Parcel Service (UPS) label that was
included in the package. For more information in the U.S. call (1) (800) 340-2445 or
visit the HPLaserJet supplies http://www.hp.com/recycle website.
●Non-U.S. returns
Customers should call the local HP sales and service office (see“Worldwide service
and support offices” on page 30) or visit the HP LaserJet supplies
http://www.hp.come/recycle website for more information about the HP printing
supplies returns and recycling program.
