Refill Instructions
HP 564 and 920 Cartridges

Updated September 09, 2010

Theory

The ink in this cartridge is retained because the cartridge has an internal sponge. However, the sponge only fills the lower half of the cartridge. The upper half is an open ink reservoir.

On the 564 and 920 series cartridges,

  • It is important to avoid air bubbles from forming in the lower sponge.
  • This cartridge does not have a printhead -- only an ink reservoir.
  • This cartridge can be refilled typically 8 to 12 times.

Required Supplies and Tools

You will need the following:
  • Bulk Ink:
    • Text/Matte Black for large black cartridge - WJ-1010 or WJ-1020
    • Photo-Black for small photo-black cartridge - WJ-1008 or WJ-1109
    • Cyan - WJ-244
    • Magenta - WJ-6053
    • Yellow - WJ-7006
    • Please note if you have a 5 cartridge system you will need two black inks. The cartridges are different and require different inks.
  • A standard luer-type syringe (20 to 30 cc is best) or one of our syringe bottles. No needle is necessary.

    Simplified Instructions for Advanced Refillers

    Step 1) Put the cartridge on some paper towels in an area where you can tolerate a spill.

    Step 2) Cover the exit port. Any of the following should work: black electrical tape, the orange cap that came with it secured by a rubber band, or in a pinch your glove covered finger.

    Step 3) Peel off the label.

    Step 4) Look for the vent hole. It should be at the end of the squiggly line.

    Step 5) These 564/920 cartridges hold approximately 4 ml. of ink. Load your syringe and slowly inject the ink.

    The 564XL/920XL holds approximately 8ml. of ink. When filling the 564XL/920XL fill as slowly as possible.

    There is a reservoir that needs to be refilled as well as a sponge.

    Step 6) After you inject the ink leave the covering on the exit port for a full minute. These little sponges need time to absorb the ink.

    Step 7) Remove the exit port cover then place the cartridge in a disposable cup or an old china one that you will not use for anything else. Let the excess ink drip for about 5 minutes.

    Step 8) Put the cartridge back in your printer and run 2 or 3 cleaning cycles.

    Instructions for Beginners

    Step 1) Put the cartridge on some paper towels in an area where you can tolerate a spill. Working over or next to a sink is a good idea.

    Step 2) Locate the ink exit hole and turn the cartridge so that this hole is facing up. Dribble some ink into this hole to fill the sponge area.

    Do not pierce the felt pad with the needle!

    Step 3)The cartridge sponge will be full when:

    A. The ink begins to drip out the vent hole on the other side. Make sure you are working over a protected area or a sink when this happens.

    B. The ink pools or puddles in the area and the cartridge refuses to absorb it. Take a paper towel and blot up any excess ink.

    Tips and Tricks

    If you are planning on storing your cartridge:

    cover all holes with electrical tape during storage to prevent leaks and evaporation. Store the cartridge in a zip type sandwich bag.

    Important Notes regarding Photo Paper

    The large black pigmented WJ-1010 or WJ-1020 inks which are suggested for use in the 4-cartridge system black cartridges are matte finish blacks, ideal for text printing and most graphics, and are very similar to to the original HP ink. However, in photo printing, this black can result in a matte appearance for black in a sea of glossy color.

    In a 5 cartridge system, good photo production is made by using the Photo-Black WJ-1008 in your smaller black cartridge.

    If it Leaks

    The most likely problem is that the seal over the fill hole is not air-tight. Check this seal. Also check for small cracks in the plastic.

    If it Won't Print

    The most likely cause is an air bubble trapped in the sponge, or between the sponge and the printhead. Remove the air bubble and you'll probably fix the problem. Remember: an air bubble is another name for "lack of ink".

    Another cause can be froth forming in the sponge. This froth is a collection of hundreds of tiny bubbles of air which forms when a small bit of ink is left behind in each sponge cell. When you refill, this froth may move into the printhead and form a vapor lock situation.

    To cure either big air bubbles or froth, simply put a single drop of isopropyl (rubbing) alcohol on the sponge through the ink exit hole, ideally before refilling. (Any concentration of the alcohol from 70 percent to 100 percent is fine.) The alcohol will collapse the air bubbles and allow for normal printing most of the time.

    To Clean the Printhead

    Do not clean the printhead unless you get poor print quality.

    Follow the directions in the printer manual.

    Run the printhead cleaning software.

    Common Clogs

    1. This printer is a sponge-filled cartridge. Because of this, it is susceptible to a common problem: Froth.

      When you use ink from a sponge-filled cartridge, a little bit of ink remains in each cell of the sponge. When you later add ink to the sponge, some air is trapped in some of the sponge cells. Then, when you print, this air/ink mixture, which we call "froth", begins to move as a mass of tiny ink-coated bubbles into the printhead. The printhead cannot print something which is mostly air -- it needs ink. Thus, the printhead vapor locks on the froth and appears to be "clogged".

      To fix the problem, simply put a single drop of isopropyl (rubbing) alcohol on the sponge through the ink exit hole, ideally before refilling. (Any concentration of the alcohol from 70 percent to 100 percent is fine.) The alcohol will collapse the air bubbles and allow for normal printing most of the time.

    2. For a real dried-ink clog, unplug the printer from both the wall and the computer, and clean the cartridge or printhead with plain, ordinary warm water. The ink will dissolve quite well in water. Unlike ball-point pen ink, this ink will not dissolve well in alcohol or paint thinner. Use ordinary warm tap water to clean this ink. Be sure to dry an electronics completely before applying power.

    To Clean Your Sink

    The ink is water-soluble. Use plenty of soap and warm water. You may also need to use Comet or a similar cleaner if the stains persist.

    To Clean Your Hands

    On hands, the best substance to use is Ink Be GoneTM, a specially developed hand cleaner available from ACSI Bulk Inks. (To place an order, Click Here.)
