MF8280CW rear door

[Technotronic]

Error says close back cover...and its closed. Cant see anything obstructing the door. Hard to make out the switch thats detecting the door open-close. Might be a sensor with a plastic flag that sticks in it not sure?

Canons site seemed to say that it could be a paper jam , but I dont see any signs of one. The separator pad in the document scanner feeder was popped loose, so I took it apart and re-attached it in place, but still have the error.
