Toner cartridge information The Toner Cartridge is designed to simplify replacement of the major "consumable" parts. The Toner Cartridge contains the printing mechanism and a supply of toner. At 5% page coverage, a Toner Cartridge will print approximately 10,000 pages. However, a Toner Cartridge should print more pages if regularly printing pages with less coverage, such as short memos. The cartridge may print fewer pages if heavy or bold print is used. NOTE: For best results, always use a Toner Cartridge before the expiration date stamped on the Toner Cartridge's box. Refilled toner cartridges While Hewlett-Packard does not prohibit the use of refilled Toner Cartridges during the warranty period or while the printer is under a maintenance contract, it is not recommended for the following reasons: • Repairs resulting from the use of refilled Toner Cartridges are not covered under Hewlett-Packard warranty or maintenance contracts. • 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. HewlettPackard also cannot predict what the long term reliability effect on the printer is from using different toner formulations found in refilled cartridges. • The print quality of HP LaserJet Toner Cartridges influences the customer's perception of the printer. Hewlett-Packard has no control over the actual print quality of a refilled Toner Cartridge. Recycling toner cartridges In order to reduce waste, Hewlett-Packard offers a recycling program, called HP Planet Partners, for used Toner Cartridges. Cartridge components that do not wear out are recycled. Plastics and other materials are recycled. HP pays the shipping costs from the user to the recycling plant. To join this recycling effort, follow the instructions inside the Toner Cartridge's box. 38 Chapter Product Operation C4224-90962
