Note The toner cartridge may print less than 15,000 images if routinely printing very dense print. Conversely, when routinely printing pages with less coverage (such as short memos), or in EconoMode, the toner cartridge may print more than 15,000 images. However, EconoMode does not extend toner cartridge component life. For best results, always use a new toner cartridge before the expiration date stamped on the toner cartridge box. Refilled Toner Cartridges & Non-HP Staple Cartridges While Hewlett-Packard does not prohibit the use of refilled toner cartridges and non-HP staple cartridges during the warranty period or while under a maintenance contract, their use is not supported for the following reasons: Repairs resulting from the use of refilled toner cartridges and non-HP staple cartridges are not covered under the HewlettPackard warranty or maintenance contract. Hewlett-Packard has no control or process to ensure that a refilled toner cartridge or non-HP staple cartridge functions at the high level of reliability of a new HP LaserJet toner cartridge or HP LaserJet staple cartridge. Also, Hewlett-Packard cannot predict the long term reliability effect on the printer when 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 uses a recycling program for used toner cartridges. Cartridge components that do not wear out are recycled, as are plastics and other materials. Hewlett-Packard pays the shipping costs from the user to the recycling plant. For each cartridge returned, HP donates one U.S. dollar to be shared by the Nature Conservancy and the National Wildlife Federation. To join this recycling effort, follow the instructions inside the toner cartridge box. 30 Chapter 1 Product Information EN
