How to Reset Ink Level Canon MX300 Cartridges

Apparently the problem is that you are choosing to install (according to Canon), cheap, aftermarket ink cartridges rather than Canon ones. Therefore the machine is not recognizing them. Try this procedure, found on another forum, that was supplied by one of the cheapo ink companies. Who better to know how to fool the machines than them. If they want to sell these ink carts, they better know who to make them work!
