The document feeder has a problem with auto detect. it turns out when i apply a little pressure to the front of the
ducument feeder door the green light comes on and the tray raises when paper is present and it runs fine.

without the pressure it would have auto detect issues. is there a sensor on the front? i know about the one in the back with the metal tab.
it almost seems like the door is bent. where is the sensor in front? or where is the sensor that actuated when you apply pressure to the front of the door?
