Managing the print cartridge CAUTION This section provides information about HP print cartridges, how to store them, how to identify genuine ones, and their life expectancy. Information also appears about non-HP print cartridges. HP print cartridges When you use a genuine new HP print cartridge, part number Q1338A (12,000-page cartridge for the HP LaserJet 4200 series) or Q1339A (18,000-page cartridge for the HP LaserJet 4300 series), you can obtain several types of information, such as the following:
amount of toner remaining
estimated number of pages remaining
number of pages printed Non-HP print cartridges Hewlett-Packard Company cannot recommend use of non-HP print cartridges, either new or remanufactured. Because they are not HP products, HP cannot influence their design or control their quality. Service or repair required as a result of using a non-HP print cartridge will not be covered under the printer warranty. If you use a non-HP print cartridge, the printer is unable to report the levels of the supplies for the printer, calculation of the number of pages remaining, and cartridge-usage information. If the non-HP print cartridge was sold to you as a genuine HP product, please call the HP fraud hotline. (See "Contacting the HP fraud hotline" on page 145.) Print-cartridge authentication The printer will let you know that a print cartridge is not a genuine HP print cartridge when you insert it into the printer. If the printer control panel message states that this is not a genuine HP print cartridge and you believe you purchased an HP print cartridge, call the HP fraud hotline. See "Contacting the HP fraud hotline" on page 145. Print-cartridge storage Do not remove the print cartridge from its package until you are ready to use it. The shelf life of a print cartridge in an unopened package is approximately 2.5 years. To prevent damage to the print cartridge, do not expose it to light for more than a few minutes. Print-cartridge life expectancy The life of the print cartridge depends on the amount of toner that print jobs require and the length of life for the components inside the cartridge. When printing text at 5 percent coverage (typical for a business letter), an HP print cartridge lasts an average of 12,000 pages (HP LaserJet 4200 series) or 18,000 pages (HP LaserJet 4300 series). This assumes that toner density is set to 3 and EconoMode is off. (These are the default settings. For details about these settings, see the description of ECONOMODE and TONER DENSITY in "Print Quality submenu" on page 159.) At any time, you can verify life expectancy by checking the supply level, as described in "Checking the supply level" on page 81. 80 3 Managing and maintaining the printer ENWW
