I have a Canon printer MP 550. When I switch on it shows a message B200, Printer error has Occurred. Unplug the power cord and contact the service centre" Can you assist please Geoff XXXX
I removed the power cord and waited 10 minutes, when I reconnected I got the same message again.
I should also mention that I have been having frequent problems lately with the message that "printer error has occurred switch off the power and switch back on again" This corrected the problem for only a short while and then came back again.
Thanks for your help. My warranty has run out so I think the answer is a new printer.
