My Canon MP560 does not recognize that print head door is open so that I can change cartridges.I have opened and closed the door several times and the print head just sits at the right side of the printer.
I had tried that a couple of days ago, with no results, I was ready to scrap it out so I tried one more thing, I picked it up and dropped it about 6 inches and that seems to have unstuck the switch. It is working again right at this time.
