6.1.3 ORIGINAL SIZE DETECTION
[A]
• The original width sensors [A] detect the original width, and 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 is activated as it is closed. It detects the original size by the
on/off signals received from each sensor.
• If a 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.
