5.3.8 PF Encoder Sensor Installation Position Adjustment

This adjustment is performed to set the distance between the PF roller shaft (grid roller)
and PF encoder sensor in the proper position. Through this adjustment, the position of
the PF encoder sensor's emitter and receptor are set properly with respect to the slits in
the loop scale for the PF motor.
