ID Sensors
There are two ID sensors above the surface of the ITB:
• The black ID sensor ! (rear) detects the black ID sensor pattern (K).
• The color ID sensor " (front) detects the three color ID sensor patterns (M, C, Y).
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 M, C, Y
colors.
