Storing print cartridges
Do not remove the print cartridge from its package until you are ready to use it.
To prevent damage to the print cartridge, minimize its exposure to direct light.
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 that facilitates
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.
