12-2. Original Size Detecting Operation
Each photo receiver of the original size detecting sensors (PC115 to 119) 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.
