I sure hope someone out here can help me. We are running a Canon W7200 impo proofer and on printer 2 there is an error that just says "Printhead error! Turn power off!!" Of course the manual is of no use so I figured I would just go through the motions of replacing the print head and put the original one back in. Here lies the dilemma: with the error on the screen you cannot access the main menu for maintenance. It does no good to turn it off and back on because the error just comes right back after initialization. Even if I had a new printhead on hand I would be in the same boat. Any thoughts?????
