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.
Using genuine HP supplies ensures the availability of all HP printing features.
Print-cartridge authentication
The printer will let you know if a print cartridge is not a genuine HP print cartridge when you
insert it into the printer. If you believe that you purchased a genuine HP supply, visit us at

Print-cartridge storage
Do not remove the print cartridge from its package until you are ready to use it.
Always store the print cartridge in the proper environment. The temperature should be
between -20°C and 40°C (-4°F to 104°F). The relative humidity should be between 10% and
90%.
CAUTION
To prevent damage to the print cartridge, do not expose it to light for more than a few
minutes.
