HP Inkjet Supplies - Storing Opened Cartridges and Printheads

Important: HP recommends that all cartridges remain sealed in the original package until they are installed.

Nozzles can crust over if supplies are not kept in properly humidified airtight containers. Ink can wick from nozzles if anything touches them.

After the tape or caps have been removed, cartridges and printheads should remain installed in the product.

  caution:

Improper storage can damage cartridges and printheads.

• If opened supplies must be stored outside of the product, place them (nozzles up) in a plastic tub with an airtight lid.
• Some cartridges have an orange cap that is twisted off to open. If these supplies have been opened, replace the orange cap before it is stored.
• Place a damp cloth or paper in the tub.
• Do not use plastic bags. Do not allow anything to touch the cartridge nozzles.
