ITB (Image Transfer Belt)
There are two ID sensors above the surface of the ITB:
The black ID sensor
The color ID sensor
Black ID Sensor
The black ID sensor is a direct reflection sensor.
The color ID sensor is a combination of a direct reflection sensor and a diffused
reflection sensor. This combination of a direct reflection sensor pair and an
additional diffused reflection sensor achieves more accurate readings for Y, M, C
colors.
