Refilling Canon 651 type refillable ink tanks


1) Remove rubber plug from ink hole and the yellow  tag marked 'PULL' from the air hole (first refill only). 

Or...attach the ink outlet clip (for subsequent refills) before removing the ink plug.

Adding ink without sealing the ink outlet first will result in the ink leaking out..!

2) Attach needle to syringe - fill the syringe with ink by dipping needle in the ink bottle and pulling on the plunger, then slowly inject ink inside the ink tank..

3) Keep adding more ink - as it transfers into the internal sponge. The sponge doesn't have to be completely saturated, but at least 50-60% fill is required for reliable operation. Fill the ink reservoir to within 5mm from the top.

Note: If the sponge is not filling at all (or very slowly), check that the air hole is open properly and/or leave the ink tank sitting for few minutes to give the ink time to penetrate the sponge. If it's still not filling, you may have to prime the ink tank. Check the refill instructions supplied with your refillable tanks or contact us for more info.

4) Plug the ink hole when the sponge is almost full. Leaving it open too long can result in overfilling of the sponge.This can cause theink tank to leak.

5) Check the tank for leaks. Remove ink tank from the outlet clip and place (or hold) it in upright position over something it can drip into. Few drops is fine, but if ink keeps dripping out, there is a problem. Don't install a leaking ink tank!
