Error message "no cartridge" won't go away on my brother mfc 420cn printer
Sorry i couldn't help on the day you nedded it. Do not be afraid to refill, it's easy once you have a go, all instructions come with the refill kits, and they instuct on your specific printer too. Follow it to the T and you can refil one colour or all, and no waste. Once refilled, replace it, reset ink levels, and try printing again. Good luck.
