I have tried turning the printer off and on, unplugging it and plugging back in. Removed almost all the paper and even added more. I have checked for jams but there are none. Not hard to close but sounds like it is not picking up that the door is closed. What can I do about this?
On the paper tray, there is a plastic tab that is used for paper open/close detection, it can easily break off ant the printer believes that there is no tray when it is inserted. below is a photo from the bottom of tray, check on your tray for 2 tabs if they are broken ( one of them)
