This original size detection method eliminates the necessity for a pre-scan
and increases the machine’s productivity.
This machine cannot recognize the original size when A5 lengthwise/HLT
paper or smaller is set on the exposure glass. Therefore, when all sensor
outputs are off, the machine will either detect A5 lengthwise/HLT or cannot
detect original size (this depends on SP 4-303).
While the main switch is on, these sensors are active and the original size
data is always sent to the main CPU. However, the main CPU checks the
data only when the platen cover is opened.
The check is done when the platen cover position sensor [A] turns on. This
is when the platen is positioned about 15 cm above the exposure glass. At
this time, only the sensors located underneath the original receive the
reflected light and are on. Other sensors are off.
The main CPU can recognize the original size from the on/off signals from
the sensors. If the copy is made with the platen open, the main CPU decides
the original size from the sensor outputs when the start key is pressed.
