Original Feed Speed - 2
This thermistor reads the temperature near the exit roller.
The exit roller expands when the temperature increases. This causes
original feed to become quicker. This causes errors in the sub scan
magnification.
Depending on the thermistor reading, the motor speed changes to
make sure that the speed of the original is constant.
