1. Enlarge the vent hole on the top of the cartridge using the 1/16" thumb drill provided.
 (Do not remove the top.)

2. Fill the syringe with 12-25 ml. of ink, insert the needle into the vent hole and push down into the center of the cartridge. Slowly inject up to 25ml. of black ink into the cartridge.

3. Set above a paper towel for half 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.

4. Replace the cartridge and run 1 - 3 cleaning cycles as per printer instructions.
Or print the following pages:

For best results, leave cartridge in printer for 8 hours after refilling so the ink can saturate the entire sponge. (Allows ink to flow to the print head).

Empty cartridges should be refilled immediately.
Also this work is done best over the sink.

A Refill Kit should include Ink plus the following:
1 Syringe
1 Thumb Drill
