Theory

The ink in this cartridge is retained because the cartridge has an internal sponge.

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

Step 2) Using a 1/16 inch drill, drill a hole on the top, lower flat surface -- 1/3rd of the way from the edge.

Step 3) Keeping the cartridge on paper towels, take a syringe bottle and fill it 1/3 to 1/2 full of ink -- about 10-15 ml.

Step 4) Insert the needle fully into the hole. Inject the ink very S-L-O-W-L-Y and watch until the sponge is saturated. You must get the needle deep into the hard sponge.

Step 8) Set above a paper towel for an hour as a drip precaution. Expect a few drips. Do not allow the cartridge to touch the paper towel at this point, since the towel will draw out the ink.

Step 9) For best results, let sit overnight before using. Tape over the vent hole if you plan to store for several days to prevent drying out of the ink.

To Clean the Printhead

1. Only clean the printhead if you get poor print quality or no print.
2. Be sure that you don't have an air bubble problem.
   • If cleaning the printhead causes the situation to get worse rather than improve, you probably have an air bubble problem.
   • If you have an air bubble problem, you need to re-inject some ink very deep into the cartridge.
3. Follow the directions in the inkjet manual to run the cleaning routine.
4. If this doesn't work, take the cartridge to the nearest hot water faucet.
   • Turn on the hot water. Let it get hot.
   • Put only the printhead portion (where the ink comes out) under the hot water for 2 to 3 seconds
   • Dry off the cartridge using a soft tissue.
   • Re-insert the cartridge into the inkjet.
   • Run the normal cleaning routine a few times.
5. If this doesn't work, soak only the printhead in simmering water for up to 2 hours. You may add up to 50 percent ammonia for really tough clogs.
