Tools required:

Buy this cartridge rather than refill it.

Steps for the #564 and #920

  1. Seal the outlet port on the bottom with a combination of plastic wrap and tape. You can also simply hold the port shut with your finger.
  2. Fill the syringe with 4 ml of ink of the appropriate color.
  3. Locate the vent hole on the top of the cartridge. You can remove the label or feel for the indentation under the label.
  4. Insert the syringe needle into the vent hole. You will be penetrating a sponge, so there may be some resistance.
  5. Inject the ink VERY SLOWLY! You must allow the sponge to absorb the ink.
  6. Let the sponge soak the ink up for about a minute.
  7. Unseal the outlet port and let the cartridge sit in a cup or bowl and equalize for another minute or so. Some ink may drip out. Do NOT place it on a paper towel as the towel will leeach all the ink out of the cartridge.
  8. Replace in the printer and run the printhead cleaning routine.

Note: You cannot "overfill" the standard cartridges and make them an XL cartridge. There is a plastic wall that encloses the sponge and prevents this. In the XL cartridges, the wall has an opening in it and allows the ink into the reservoir chamber.

Steps for the 564XL and 920XL

  1. Seal the outlet port on the bottom with a combination of plastic wrap and tape. You can also simply hold the port shut with your finger.
  2. Fill the syringe with 8 ml of ink of the appropriate color.
  3. Drill a small hole on the reservoir side of the cartridge above the window.
  4. Insert the syringe needle into the hole and VERY SLOWLY inject the ink into the reservoir.
  5. Seal the hole with tape or glue or hot wax.
  6. Unseal the outlet port and let the cartridge sit in a cup or bowl and equalize for another minute or so. Some ink may drip out. Do NOT place it on a paper towel as the towel will leeach all the ink out of the cartridge.
  7. Replace in the printer and run the printhead cleaning routine.

NOTE: These cartridges contain a counter chip. When this counter reaches zero, an reror message isgenerated. By clicking "OK", the printer will continue to print, but the ink level will be unknown.

On some HP printers, simply click through the various warnings and continue printing.

On other HP printers, you can hold the RESUME or RESET buttons for 15 seconds and the printer will be reset so that it will print with the refilled cartridge.
