Sensor Construction
The ID Sensors (also called the TM/ID sensors) are used to measure the amount of toner on the transfer belt and to correct any errors in color registration.
The TD sensor (also called the 
sensor) is used to measure the toner density in the developer.
Outline of the ID Sensors
The ID sensors are fixed onto the main frame, against the surface of the transfer belt. Color registration is checked by all three sensors; the front [A], center [B], and rear [C].
The center sensor [B] acts as an ID sensor and a MUSIC sensor.
