Fix Error Code 6000 and C000 on Canon printer

When there is an error code 6000 or C000 on a Canon printer, do not rush to go through the reset or any magic "press button" things. Even if you clear the message, the problem won't go away and the message will reappear. The message 6000 and C000 refer to an obstruction in the printer. Usually something on the way of the carriage unit. It can be a dirty timing strip which needs a cleaning, but most of the times it will just be a pieced of a ripped paper or any other object inside the printer. The tricky part is that it will usually be at one or the other end of the printer. Take yuur flashlight or flashlight app on your phone and shine some light inside your printer. I almost guarantee you that you will find something!
