2.3.2.1 Exposure Section: Construction and Function
1 Reflector Tape
When a book or other bound original is copied, the paper in the area near the binding generally fails to
come flush against the glass, so that the copy of these areas is generally too dark. The Reflector Tape
reduces this problem by reflecting light from the Exposure Lamp onto these areas of the original.
2 Exposure Lamp
A fluorescent lamp is used to illuminate the original.
3 Mirror A
Directs the reflected light from the original to the Mirror B.
2.3.2.2 Original Size Detection
When the machine is in Auto Paper or Auto Size, the original length detecting sensor mounted in the
FBS section receive light reflected off the original to allow the machine to determine the original length
size. And the CCD detects original width by reflecting light from the Exposure Lamp.
