Hi all, I have a problem with a fairly new 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, but sometimes I get the same message a couple of times during the same picture. 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 and what type of switch this is? I am a service tech and 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.
