How to Refill Epson Edible Ink Cartridges: A Step-by-Step Guide

Refilling Instructions:

1. Position the Cartridge: Hold or support the cartridge in an upright position.
2. Check the Air Hole: Leave the yellow air hole tape in place for now. Removing this too early will cause leaks.
3. Prepare the Ink Hole: Remove the small ink plug from the refill hole. Keep it safe; you will need it again shortly.
4. Fill the Syringe: Securely attach a blunt needle to your 10ml syringe. Dip the needle into your edible ink bottle and slowly pull the plunger to the 10-12ml mark. Note: Do not pull the plunger all the way out of the syringe!

5. Inject the Ink: Slowly fill the ink reservoir through the hole until the ink is roughly 5mm from the top. If one syringe is not enough, repeat the process.
6. Seal and Vent: Plug the ink hole securely. Now, remove the yellow tape (or plug) from the air hole. Do not forget this step, or the printer will not print!

Check Your Work: The "Air Balance" Test

PERFECT: If your cartridge looks like the image above, well done! The air balance channel (the small section under the air hole) is empty. You can skip to Step 9.

WARNING: If your cartridge looks like this (ink in the small air chamber), STOP. The air balance channel must be empty for reliable operation. If you use it like this, the cartridge will leak. Follow the steps below to fix it.

How to Fix an Overfilled Air Channel

Step 8: Remove excess ink from the air channel using an empty syringe with a tapered tip (no needle).

Push the syringe tip tightly into the ink hole. Slowly pull on the plunger to suck the ink back from the small air channel into the main reservoir.

When the air channel is almost empty (as shown above), carefully disconnect the syringe.

Final Steps

9. Plug the ink hole. If the main ink level dropped significantly during the fix, you can top it up first.
10. Clean Up: Rinse your syringes in clean water immediately so they are ready for next time.

All done! Your printer is ready to go.
