Refilling Method:

Please cover your working area with newspapers or paper towel.

1.         When viewing the top of the cartridge, you will see a single vent hole. To enlarge the vent hole, thread the eyelet drill into the vent hole until it goes through the top.  Remove the eyelet drill.

2.         Draw 12ml of ink into the syringe and insert the needle through the vent hole as far as it will go into the cartridge and inject the ink slowly.  The cartridge may not take all of the ink.  If the ink is bubbling out of the sponge, you are injecting too fast.  To insure the best refill, pause  occasionally and let the sponge soak up the ink.  Do not push the syringe down so far as to plug the hole; air must be allowed to escape during the refill process.

3.         Rinse the syringe and needle in warm water and store in a safe place for future refills.

4.         Tape up the vent hole and insert the cartridge back into the printer.
