Instructions

1. Put the cartridge on some paper towels in an area where you can tolerate a spill.

2. Seal the outlet hole(s) with the aluminum tape provided.

3. Fill the syringe with 10 ml. of black ink or 5 ml. of color ink.  Push needle through the label into the sponge of the correct filling hole. On the color cartridge the inks from left to right are, CYAN - MAGENTA - YELLOW (You can double check the ink colors by looking at the outlet ports before putting on the tape) 

4. Very S-L-O-W-L-Y inject ink into the sponge until the cartridge is full. A little ink might come out of the top when full, so cover up the other two holes while filling one.

5. When finished, seal the Filling Hole(s) made in the top label with tape.  If the holes are not sealed properly the cartridge will leak.

6. Important - Next, remove the Tape from all exit port(s).

7. Replace the cartridge and run 1 - 3 cleaning cycles as per printer instructions.

Check your printer's user manual about resetting the ink levels back to full. If your printer does not have this option of resetting the cartridge then you will need to deactivate the ink level monitor.

An alternate method of refilling if you are careful would be to leave the cartridge in the printer and to top off the colors (or black) very S-L-O-W-L-Y. Be sure to seal the filling hole(s) with tape after refilling.
