Hi all, I have a problem with a Canon 6700 photo printer. When I turn it on and get ready to print, I often get the the error message while printing that the output door is closed, even though it is open. I can play with the door and the message will go away and the picture continues to print for a couple seconds, but goes into the error again. I feel it is a switch problem that is borderline. I have found by lifting the door slightly, the problem goes away. Seems weird to LIFT the door to help it, but thats the deal. Does anyone know where the switch is located and what type of switch it is? I do service work for a living and I am willing to fix this myself if possible, but not having a manual on this unit makes it a little more difficult. Any help is appreciated.
