Toner cartridge refill statement
Hewlett-Packard toner cartridges have been designed to maximize the 
reliability of the HP LaserJet printer by including all of the components 
that need frequent replacement or adjustment within the cartridge. 
While we recognize that all parts of this critical printer mechanism will 
not wear consistently, the HP toner cartridge has been designed to 
optimize the exceptional print quality that is synonymous with the 
HP LaserJet printer name. While Hewlett-Packard does not prohibit the 
use of refilled toner cartridges during the warranty period or under a 
maintenance contract, we also do not recommend their use for the 
following reasons:
The HP LaserJet toner cartridge is not designed to be refilled or 
remanufactured.
Hewlett-Packard has no control or process to ensure that a refilled 
toner cartridge will function at the high level of reliability of a new 
HP LaserJet toner cartridge. Hewlett-Packard also cannot predict 
what the long-term effect on the printer's reliability could be from 
using different toner formulations found in refilled cartridges. 
Because the HP LaserJet printer has the highest reliability 
reputation in the industry, we are concerned about any usage that 
might affect this reputation.
Hewlett-Packard has no control over the actual print quality of a 
refilled toner cartridge. The print quality of the HP LaserJet toner 
cartridge directly influences the customer's perception of the 
HP LaserJet printer itself. The high print quality of the HP LaserJet 
printer is one of the primary reasons for the success of the product 
and we are keenly interested in maintaining that image.
