AIDC Detection
• Patterns are produced on the Transfer Belt and AIDC Sensors detect the amount of
toner sticking to the patterns.
1. The light-emitting diode emits infrared rays illuminating the toner pattern on the Trans-
fer Belt.
2. The photoreceiver detects the intensity of the infrared light reflected off the toner pat-
tern on the Transfer Belt.
3. A voltage corresponding to the intensity of the reflected light is output to the PIC Board.
