I have a Canon Pixma MG5220 color printer [actually it’s what Canon calls an “all-in-one printer” -DT] and all of a sudden it’s popping the error code B200, showing the message “Printer error has ocurred. Unplug the power cord and contact the service center.” on the tiny screen. Windows 7 has no idea there’s anything wrong when I try to print. It just doesn’t work. What does “B200” mean and how do I fix it?
