My Canon Pixma has a message on LCD screen "he following Ink Tank cannot be recognised" The tank is only a week or two old and has been working perfectly prevously.Do you have a solution to the problem ?
Same problem on my MX700, yellow tank not found, I took it out and then replaced it... worked fine for two days then the same problem, now that doeant help anymore by taking it out... I guess I will have to buy a new tank, by the way the peinter is one month old and seldom used.
