Our refillable cartridges were created to simplify the refilling of printers using HP 70 original cartridges. Refilling InkPot's refillable cartridges is as easy as counting one, two, three. 1- Remove the cap. 2- Inject ink. 3- Replace the cap. That's all!

These cartridges have auto-reset chips. When a cartridge shows "empty", remove it, refill it, and then when you reinstall it, it will show "full".

*IMPORTANT* The cartridges provided with this product are empty. You will also need to purchase an inkjet refill kit that is compatible with these cartridges. See our 120ml Refill Kit for HP DesignJet Z5400.
