10-2. Original Size Detecting Operation
Each photo receiver of the original size detecting sensors responds to reflected light of a
given intensity with reference to the intensity of the light emitted by each LED. This allows
the Original Size Detecting Board to determine whether or not there is an original within a
set distance.
