I hope someone here has done it and can help me, because I am stumped! I have a Canon printer with the IP42 tanks, set of 4. I bought some bottles of ink so I can refill the tanks but the instruction sheet that comes with it does not have my tanks on it and I cannot find anything on Kopykake's website. The tank inside has a chamber which is full of ink when the cartridge is new, and another chamber next to it which has a spongy thing in it. On top there is a little hole with the spongy stuff exposed. I am supposed to plunge the needle on the ink bottle into the sponge and squirt the ink in that way? I tried but I am making a hideous mess and nothing seems to leak into the other chamber. Aaaargh! Please help!

Anybody? While I am waiting I need to go and scrub my hands, have ink up to my elbows!
