Managing the print cartridge
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.
CAUTION 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 .
