How to refill Canon PGI 550 and CLI 551 cartridges by using Fill Bill Focus™ CP550 refill tool

At first you need to set the Fill Cuff that is provided for the colour of the cartridge that you want to refill into the Cuff holder of the Fill Bill. Hint: Do not use a Cuff with which you have refilled another colour earlier. That could lead to colour mixing which you could see in the print out later. Now clamp the cartridge into the Fill Bill. For that place the PGI 550 or CLI 551 upside down onto the rubber mat of the FIll Bill. Slowly lower the clamping lever and position the cartridge so that the seal of the Fill Cuff exactly seals the ink outlet.

Now we get to the part were you actually refill the cartridge. After you have placed the cartridge and screwed the syringe filled with the ink onto the Fill Bill you create a vacuum inside the cartridge. For that pull the plunger slowly up about 30ml. Thus the air from the cartridge streams through the ink into the syringe. When you let go of the plunger the ink replaces the vacuum inside the cartridge. Repeat this process two or three times. Please work carefully you do not need power for the process. The cartridge will be refilled after the second or third time. When you pull the plunger up and ink streams into the syringe instead of air, than the cartridge is refilled.
It is possible that there is ink left inside the syringe. Do not be irritated by that, simply safe the ink for the next refilling.

That is it. You need to remove the refilled cartridge from the Fill Bill by opening the clamping lever.
Advice: If you filled in to much ink it is possible that it drops from the ink outlet. In this case use some paper towel to soak up the ink. It should soon stop dropping.
