HP #22 C9352A Tri-Color Cartridge
The ink in this cartridge is retained because the cartridge has an internal sponge. This cartridge is physically identical with the #28 C8728AN cartridge. HP puts less ink into this other cartridge when new.
Step 1) Put the cartridge on some paper towels in an area where you can tolerate a spill.
Step 2) Remove the label on the top of the cartridge. You will find 5 holes.
Step 3) Put the holes on top of the cartridge. Stick a toothpick or an unbent paper clip into the hole you'd like to fill. See what color comes up!
Step 4) Keeping the cartridge on paper towels, take a syringe bottle and fill it 1/5 full of ink -- about 6 ml. When new, the cartridge holds 17 ml. When full, the cartridge holds 17 ml.
Step 5) Insert the needle fully into the hole. Get the tip of the needle to the bottom of the cartridge. 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 6) It is not necessary to reseal the holes.
Step 7) Set above a paper towel for an hour as a drip precaution, perhaps over a small cup. 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 8) For best results, let sit overnight before using. Tape over the vent holes if you plan to store for awhile to prevent drying out of the ink.
