HP Laserjet 8000DN Manual Feed sensor stuck

I have a HP  Laserjet 8000DN with a sensor on the manual feed that is stuck so that it allways thinks it has paper in the feed tray. Any quick and dirty way to fix this?

This printer also has the Tray 3 feed problem, Which I will order MOEs 2nd pass kit for when its available.

Thnks in advance, Moe's kits have cut my printer expenses by 20%. If more kits were available Im sure the savings would increase. Thnks Moe!
