Step 1) Put the cartridge on some paper towels in an area where you can tolerate a spill.
Warning: This cartridge can be extremely messy to refill. Please wear latex or rubber gloves and old clothes. Cover all surfaces that the ink can drip onto with newspaper.
Step 2)
Step 3) Take the cartridge and locate the hole on the bottom through which the ink normally exits the cartridge. (There is often a dark plug in this hole.) This is the exit hole.
Step 4) On the bottom, you will also find another hole. This is the vent hole. It should be located on the same side of the cartridge as the large ring-like handle on the top of the cartridge.
Step 5) Turn the exit port down (toward your lap). Place the exit hole on the left and the vent hole to the right.
Step 6) Using black electrical tape (NOT giftwrap tape, duct tape, or masking tape!), tape over the exit port so that it is sealed air tight. If the port is not sealed, you will have a large leak when you put in the new ink.
Step 7) Remove the catridge handle from the top of the cartridge by bending it up and prying the end loose with a flat-headed screwdriver or similar device.
Step 8) You will now see two metallic seals. The smaller one seals a round hole, while the larger one seals a rectangular hole.
Step 9) Remove the metallic seals or poke holes through them with the syringe needle.
Step 10) Fill the syringe bottle with ink. Use:
Step 11) Take the syringe bottle and inject the ink slowly into the sponge through the rectangular hole on the top right of the cartridge.
Push the needle deeply into the sponge and slowly lift the needle so that the entire sponge is saturated with ink. Try to eliminate any air bubbles.
Step 12) Now inject additional ink into the top round hole on the top left of the cartridge until the outer chamber is completely full of ink.
Step 13) Using black electrical tape, seal the top round hole above the outer chamber airtight. You must get this seal airtight or there will be a large leakage of ink!
Step 13) Seal the top rectangular hole with black electrical tape. It is not as necessary to get this hole airtight.
Step 14) Snap the top catridge handle back into place.
Step 15) When ready to install in the inkjet, go to a sink first.
Over a sink, remove the tape on the bottom of the cartridge. Expect a few drops of ink to leak out. This is normal. However, be sure that there is plenty of ink left in the bottom of the outer chamber.
Step 16) Install in inkjet.
Clean the printhead only if the cartridge doesn't print or prints in streaks.
Follow the directions in the inkjet manual.
