Once the chip on the cart records an out of ink message your will get that response from the printer, even after refilling. If you were to find that the printer can be brought back to proper function and start refilling your carts you would probably buy a chip resetter so the printer recognizes the carts as containing ink. Someone with a chipped printer can tell you how to continue testing your printer and resume printing by bypassing Canon's death spell on the printer when it senses that you either have empty carts or have refilled them.
