HP8720 door open error-Where is door sensor activator

[8720helpme]

My 8720 cover is closed.  Yet I get an error stating the door is open.  I have tried the unplug, plug back in resets.  Still have error.  I tried looking for a door sensor activator but can't find it.  Any ideas?  Does anyone know where it may be so I can see if it needs replacing?  Could it be another reason I can't get rid of error?
