4. IMAGE STABILIZATION CONTROL
• he printer provides the image stabilization control as detailed below to ensure stabilized
print image.
4-1. AIDC Detection
• The amount of toner sticking to the Image Transfer Belt is measured and color reproduc-
ibility is stabilized.
1. A light-emitting diode is used to emit infrared rays that illuminate the toner pattern on
the Image Transfer Belt.
2. The photo receiver detects the intensity of the infrared light reflected off the toner pat-
tern on the Image Transfer Belt.
3. A voltage corresponding to the intensity of the reflected light is output to the Master
Board (PWB-A).
