The ink in this cartridge is retained because the cartridge has an internal
Step 1) Put the cartridge on some paper towels in an area where you
can tolerate a spill.
Step 2) Using a 1/16 inch drill, drill a hole on the top, lower flat surface --
1/3rd of the way from the edge. Make the hole about where the letter "E" in LEXMARK is molded
into the top surface. (For Compaq cartridges, look for the "O". For Dell, look for the "E". For Xerox, look for the "E".)
TIP: You may take a large paper clip, unbend it, and heat it in a flame to melt
a hole instead of using a drill.
Step 3) Keeping the cartridge on paper towels, take a syringe bottle and
fill it 1/3 to 1/2 full of ink -- about 10-15 ml.
Step 4) Insert the needle fully into the hole. Get the tip of the needle to the bottom of the
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 8) It is not necessary to reseal the hole.
Step 9) Set above a paper towel for 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.
Step 10) For best results, let sit overnight before using. Tape over the vent
hole if you plan to store for several days to prevent drying out of the ink.
To Clean the Printhead
- Only clean the printhead if you get poor print quality or no print.
- Be sure that you don't have an air bubble problem.
- If cleaning the printhead causes the situation to get worse rather
than improve, you probably have an air bubble problem.
- If you have an air bubble problem, you need to re-inject some ink
very deep into the cartridge.
- It can also be useful to put a single drop of isopropyl rubbing alcohol deeply into the cartridge.
- Follow the directions in the printer manual to run the cleaning routine.
- If this doesn't work, take the cartridge to the nearest hot water faucet.
- Turn on the hot water. Let it get hot.
- Put only the printhead portion (where the ink comes out) under the hot
water for 2 to 3 seconds
- Dry off the cartridge using a soft tissue.
- Re-insert the cartridge into the printer.
- Run the normal cleaning routine a few times.
- You may repeat this hot water routine a couple of times.
- If this doesn't work, you may wish to rinse out the entire cartridge by injecting the cartridge repeatedly with warm water.
After rinsing, suction out as much water as possible with a syringe, then dry out the cartridge in a food dehydrator or by
putting in front of an air conditioning or heater vent for 12 to 24 hours.
- If this doesn't work, soak only the printhead in simmering water for
up to 2 hours. You may add up to 50 percent ammonia for really tough clogs.
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.
