Hello, I have exactly the same problem. My printer is approx. 2 years old (a Canon MG6650) and it worked perfectly. Yesterday, it printed two pages and as I wanted to print another one, I received the error code B203 "unspecific problem, please turn off the printer and let it check by the service center". There has never been a problem before, there were no strange sounds or anything extraordinary. I have a specific doubt: this is caused by a self-destroying programme which was installed by the producer in order to boost the sale because buying a new product is less expansive than repairing it... I am very upset, I don't want to spend money again, don't want to produce waste, and I really do think that printer isn't broken aktually... Please share youre experiences and ideas! Thanks
