1. Place a small strip of the aluminum tape provided over the ink outlet hole and vent hole located at the front of the cartridge. Make sure the cartridge is dry before you do this to insure you get a good seal. If you do not do this ink will leak out of the cartridge.

3. Holding the cartridge at a 45 degree angle with the ink outlet holes facing up, slowly inject up to 4 ml. of color ink, and up to 8 ml. of black ink into the filling hole until the chamber is almost full. Unused ink may be returned to the bottle.
4. Seal the filling hole with the aluminum tape provided, ensuring that the tape has sealed the hole completely.
5. Clean the syringe with water and dry for future use, or use with a different color ink.
6. Replace the cartridge and run a cleaning/priming cycle as per printer instructions.
