Storing print cartridges
Do not remove the print cartridge from its package until you are ready to use it. Some
HP LaserJet print cartridge packages are stamped with an alphanumeric date code. This code
represents a 30-month period beyond the date of production in order to facilitate efficient
inventory management processes between HP and its resellers. It does not serve as an
indication of toner life (shelf-life) or relate in any way to warranty terms and conditions.
To prevent damage to the print cartridge, do not expose it to light.
