Step 2) Bend the last 1/4 inch of the end of the syringe needle to a 45 degree angle. Fill the syringe bottle 1/4 full of ink -- roughly 7 ml.
Step 3) You should see two rows of vent holes on the lower half of the cartridge. They are probably under the label. Locate the second vent hole from the bottom. Insert the needle here.
Step 4) Angle the needle toward the back wall where the reservoir and the foam area intersect. Rotate the needle so that the needle is bent downward. There is an small channel here that you are trying to reach. If the needle cannot reach it, be sure to get under the foam.
Step 5) Very S-L-O-W-L-Y inject the ink so that it flows into the ink tank.
Step 6) On most of these cartridges you can see the reservoir fill. Repeat for the other colors.
Step 7) Tape over all vent holes and air channels with electrical tape to prevent leaking during storage and transportation. Remove the tape just before you print.
Step 8) Set on a paper towel for an hour as a drip precaution.
Step 1) Put the cartridge on some paper towels in an area where you can tolerate a spill. Place the cartridge with the top facing up. Tape over the exit holes.
Step 2) Drill a 1/16 inch (1.5 mm) hole in each ink reservoir.
Step 3) Inject the ink into these holes.
Step 4) Seal the holes with hot glue or hot wax or electrical tape. You must get an airtight seal to prevent a major leak.
Step 5) Tape over all vent holes and air channels with electrical tape to prevent leaking during storage and transportation. Remove the tape just before you print.
Step 6) Set on a paper towel for an hour as a drip precaution.
