The ink in this cartridge is retained because the cartridge has an internal
For best results, never
leave your Epson printer without an installed cartridge -- even an
empty one -- for more than
an hour or so, because the ink -- the original or our refill ink --
will begin to gel to the consistency of honey, which will require
multiple cleaning routines to clear.
The most common problems when refilling this cartridge are air
bubbles trapped in the sponge because:
- Air has filled the exit tube.
- You refilled too quickly.
- You did not angle the syringe needle properly.
Step 1) Put the cartridge on some paper towels in an area where you
can tolerate a spill. Wear old clothes. You may wish to wear rubber gloves
if you don't wish to temporarily stain your fingers.
Step 2) Locate the ink exit hole(s) on the bottom of the cartridge.
Remove the old black rubber plug(s) by peeling them out with a knife.
Replace the plugs with our Epson-compatible plugs which are available for
purchase (see below). These plugs install into the ink exit hole and are particularly
good if you plan to store your cartridge for a few days before using.
Alternatively, you may wish to tape over the ink exit hole with black
electrical tape, but this is not as effective at avoiding air bubble
Step 3) Place the cartridge so that the ink exit holes are flat on the
surface in front of you. There are six vent holes under the label on the
top surface of the cartridge.
Step 4) Locate the vent holes on top. They
may be under the label or taped. Locate the second row of vent holes nearest
the ink exit hole. You may need to peel off the label.
Open the holes if they are under the label or taped and place the cartridge
back on the table surface as in Step 3.
Step 5) Check each hole with a toothpick if you are not certain of which
color goes into each hole.
Fill the syringe bottle 1/3rd (10 ml) full with the correct color of
ink and insert fully
through the hole on top which is closest to the exit hole.
Angle the needle toward the exit hole. It is very important that the needle
penetrate deeply and get under the sponge.
Step 7) Important Angle the needle toward the exit hole
and inject the ink very S-L-O-W-L-Y.
Too fast and you will "vapor lock" the foam because air
bubbles will form. You must get the needle to the bottom of (under)
the sponge and fill to remove all of the air from the cartridge.
Repeat the procedure for the other colors.
Step 8) If you chose to use the plugs, wipe off any spilled ink and put
the cartridge into the printer. Remove the tape from the top holes to print.
If you chose to tape the ink exit holes, go to the sink.
Remove the tape from bottom.
Leave the top hole open to print, but
you may wish to seal it with tape during long term transport or storage.
Step 9) Let the cartridge drip over the sink for 2-3 minutes. Do
not set the cartridge on a paper towel as this will suction too
much ink from the exit hole.
Step 10) When preparing to insert the cartridge, take a paper towel
and remove the ink from the exterior of the cartridge. Use
the paper towel to remove the last hanging drop -- but do not dry the inside
of the cartridge. (You need just a little bit of ink ready to fill the
At this time, we also recommend taking a cotton swab and cleaning any
ink from the well where you will insert the cartridge.
Caution: If ink is spilled on the circuit board below the
cartridge holder area, it can cause a short on the circuit board.
Step 11) Quickly insert the cartridge in the printer.
Step 12) It may be necessary to run the software printhead cleaning
routine a few times to prime the printhead.

If the Printhead appears clogged
The most likely problem is that you have an air bubble in the exit tube
of your cartridge. Remember that the absence of ink is the same as an air
bubble. You can confirm that this is the problem if the printhead cleaning
routine actually makes the problem worse.
What is happening is that a small air bubble expands under the vacuum of
printing to form a large air bubble, which blocks the flow of ink to the
printhead. This problem usually occurs after printing 1 or 2 good pages.
To clear the problem, you may wish to let the printer sit without printing
for several minutes, while tapping on the top of the cartridge. This may
get the air bubble to move to the top of the cartridge. It may not.
Another idea is to remove the cartridge and try again. Also, try putting a
single drop of ink directly into the point where the cartridge is plugged
into. But be very careful not to spill the ink!
To Clean Your Sink
The ink is water-soluble. Use plenty of soap and warm water. You may also
need to use Comet or a similar cleaner if the stains persist.
To Clean Your Hands
On hands, the best substance to use is
Ink Be GoneTM, a
specially developed hand cleaner available from ACSI Bulk Inks.
