Filling an empty HP 901 ink cartridge is a simple task that you can do yourself. They are designed with a convenient filling hole on the top of the cartridge, which allows you to add more ink once you empty the ink that was already inside. You will only need ink with which to fill the cartridge and a syringe with which to get the ink inside the cartridge. You can use a plastic or metal syringe as long as the needle fits into the hole in the cartridge.

  1. 1

    Remove the ink cartridge from the printer. Lift the cover up to make the ink cartridges move into view so you can pull the empty cartridge out.

  2. 2

    Peel back the label on the top of the cartridge. This will expose a small hole in the cartridge that you will fill it through.

  3. 3

    Insert the needle of a syringe into a bottle of printer ink and fill it up. You will need to about 8ml (8cc in the syringe) of ink to fill out a black cartridge and about 5ml (5cc) of ink to fill a coloured cartridge.

  4. 4

    Take the needle out of the ink and insert it into the hole in the top of the ink cartridge.

  5. 5

    Depress the top of the syringe to release the ink into the cartridge. Keep an eye on the hole to make sure no ink is coming out. Stop filling the cartridge as soon as you see ink coming out of the hole.

  6. 6

    Pull the syringe out of the cartridge and press the label back into place.

  7. 7

    Let the cartridge rest overnight on a nonabsorbent material like metal to let the ink settle.

  8. 8

    Place the ink cartridge back into the printer and use as normal.

Tips and warnings

  • Printer ink stains, so keep absorbent materials away from the area you are working in.
  • Be careful when handling syringes, as the needles are sharp and can cause injury.
