Refill ink in one or more ink tanks of your HP Smart Tank 670, 720, 750, 790, 6000, 7000, 7300, or 7600 series printer when the ink level is low.
Fill empty or low ink tanks using official bottles of HP ink.
Be aware of the following when working with ink bottles:
Keep the ink bottles beyond the reach of children.
Open the ink bottle only when you are filling the ink tanks.
Store the ink bottles upright in a cool, dry place.
To avoid possible printhead damage, do not install the printheads until you have filled the ink tanks.
