6.4.3 ORIGINAL SIZE DETECTION
 The original width sensors [A] detect the original width. The original length sensors [B]
detect the original length.
 The SBU controller on the SBU board checks each sensor status when the platen
cover sensor [C] is activated as it is closed. It detects the original size by the on/off
signals it gets from each sensor.
 If the copy is made with the platen cover fully open, the SBU controller on the SBU
determines the original size from the sensor outputs after the Start key is pressed.
