The DF registration sensor is activated by paper dust on the sensor pad, affecting its color. This is because, when the original roller starts rotating, the DF upper plate is warped slightly downward. The clearance between the DF registration sensor and the sensor pad is reduced. To prevent this the pull-out bracket has been modified to improve the clearance.
