Theory of Operation
Temperature/Humidity Sensor
The Temperature/Humidity Sensor monitors the internal temperature of the 
system. It is also used for image stabilization, transfer ATVC, and fusing 
temperature control.
There is a Control Panel command which obtains environmental temperature 
and humidity levels. However, this command is for internal use only and not 
available from the service menus.
