Hi, i'm new to this forum, i bought a canon ip4300 a while ago and found that it was costing me a lot of money to buy the genuine ink carts for it, so i decided to start refilling the carts as i was doing with the older canon ip4000. no problem with that one but with the ip4300 once i topped up the cart and replaced it, the printer would not recognise the cart due to the chip, i even bought a set of compatable carts and attemted to fit the chips from the empty ones to the compatable ones but no joy. can anybody assist me to overcome this problem? it's driving me skint. Thanks jack
