Cartridge maintenance
Proper use and handling will provide high print quality and longer print cartridge life. Print at least once a month to keep the nozzles clear and the print cartridges in good working order. The printer automatically primes, cleans, and caps the cartridges to maintain optimum print quality; these operations are not visible to users. Refer to the following table for guidance on storing and handling HP Inkjet cartridges:
Do
Do not
Keep Inkjet cartridges sealed in the original packaging until ready to use. Ink can evaporate through the nozzles and the plastic body, reducing ink product life. Therefore, ink products have a longer life when sealed in the packaging.
Do not reapply tape to a tri-color print cartridge. Attempting to reapply the tape can cause colors to mix, ruining the cartridge.
After removing the cartridge from its packaging, store it in the printer in the "home” position to help prevent ink from drying out in the nozzles. This will also minimize the risk of contamination with airborne dust particles.
If you must remove a cartridge from the printer:
  1. Place the cartridge in an airtight, rigid plastic container. Use the cartridge protector provided with HP photo cartridges, if available, to keep the nozzles from touching the container.
  2. Store the COLOR cartridge with nozzles DOWN.
  3. Store the BLACK cartridge with nozzles UP.
  4. Seal the container.
  5. Store at room temperature.
Do not allow the nozzles on the bottom of the cartridge to touch the bottom or side of the rigid plastic container. If the nozzles contact the container, the ink colors could mix, or ink could drain out of the cartridge.
Do not re-tape the cartridge.
Do not place the cartridge in a plastic bag.
Turn the printer OFF by pressing the power button. Turning the power button OFF directs the printer to cap the cartridge in the service station which helps prevent ink from drying in the nozzles.
Do not unplug the printer without first turning it OFF by pressing the POWER button. This will leave the cartridge vulnerable to evaporation and dust contamination.
Store Inkjet print cartridges at room temperature.
It is not necessary to refrigerate Inkjet print cartridges.
Store packaged Inkjet print cartridges in an upright position.
Do not store a packaged Inkjet print cartridge on its side or upside-down for long periods of time.
