The W 92274.4 Toner Cartridge
Refilled Toner Cartridges
While Hewlett-Packard does not prohibit the use of refilled toner
cartridges during the warranty period or while under a
maintenance contract, we do not recommend their use. The
reasons for this are:
Hewlett-Packard has no control or process to ensure that a
refilled toner cartridge functions at the high level of reliability
of a new HP LaserJet toner cartridge. Hewlett-Packard also
cannot predict what the long term reliability effect on the
printer is from using different toner formulations found in
refilled cartridges.
Hewlett-Packard has no control over the actual print quality of
a refilled toner cartridge. The print quality of HP LaserJet toner
cartridges influences the customer’s perception of the printer.
Re~airs resultimz from the use of refilled toner cartridges are
no{ covered und& the HP warranty or maintenance contract.
Recycling Toner Cartridges
In order to reduce the amount of plastics and other wastes
entering our landfllls, Hewlett-Packard has established a program
for recycling used toner cartridges. Parts that do not wear are
re-used in manufacture of new cartridges. Plastic and other
materials are recycled. HP pays the shipping costs. In addition, a
one dollar donation is shared by the Nature Conservancy and the
National Wildlife Federation for each cartridge returned under
this program. To join this recycling effort, follow the instructions
included inside each toner cartridge box.
