13-4. Size Detection
• Original Size Detecting Board reads the output data provided by the original size detect-
ing sensors. By comparing the data from each sensor with the threshold level, it deter-
mines whether there is an original placed on the Original Glass. Original Size Detecting
Board then determines the size of the original according to the combination of the data.
