Question : Problem: Tray 2 is full but it says its empty

I have already checked the message posted by Fluid_Imagery on this subject.

I have already switched to a new paper tray and put in a new paper sensor with no change.  Looks like there is a switch on the bottom of the tray that releases the metal plate that pushes it up to the sensor but Im not sure how that works.  I dont hear it releasing and pushing up to the sensor at all.  

Answer : Problem: Tray 2 is full but it says its empty

Does the tray elevate after you shut the drawer?

If it doesn't, then remove the tray and look under for the release clip, it should have a spring on it.  It sounds like on the printer frame, the release is bent or broken.

Try check that and let's see.
