HP 4300 Service Manual - Page 51

Print-cartridge information 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: q Repairs resulting from the use of refilled print cartridges are not covered under Hewlett-Packard warranty or maintenance contracts. q 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 reliability effect on the printer from using the differing toner formulations that are found in refilled cartridges. q The print quality of HP LaserJet print cartridges influences the customer's perception of the printer. Hewlett-Packard 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 q U.S. returns For a more environmentally responsible return of used print cartridges and supplies, HP encourages the use of bulk returns.
