1 . The filling holes are located
on the top of the cartridge and are sealed with small plastic plugs. These must be
removed by pushing them into the cartridge using a pointed instrument. (A ball point pen works well or a push pin).
2. Don't go by the label on the front of the
cartridge when putting in ink, it's not in the correct order. Go by our
diagram here. You can also stick the long needle in a chamber and wipe it
with a paper towel to verify the correct color
chamber.
3. Fill the syringe with 8cc of ink. Insert the filling needle into the
filler hole of the color to be refilled (see diagram) and push downwards into the bottom
of the cartridge. Note the cartridge contains a sponge and a slight resistance may
be felt. 
4. S-l-o-w-l-y inject the first 3cc toward the bottom then inject the other
5cc s-l-o-w-l-y in the middle. (If all the ink is injected
at the bottom where the printhead is, some of the color will seep into another colors
chamber and cross contaminate. If this happens it will eventually flush itself out with
printing) Do not reseal the filling holes (the
original plugs had vents to let air into the cartridge, as ink is used it
needs to pull air into the cartridge). Important: Do not
inject the last cc if it is air bubbles
5. Set above a paper towel for a few minutes as a drip precaution. Do not allow the
cartridge to touch the paper, since the paper will draw out the ink.
6. Place the cartridge back into the
printer. It is best to fill the cartridge at night
just before going to bed and let the cartridge sit in the printer after a
refill for 8 hours so the ink can stabilize in the sponges. The next day
run 1 - 3 cleaning cycles as per printer
instructions.

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

after refilling read this:
