The original size data is taken by the main CPU when the DF position sensor is
activated. This is when the ADF is positioned about 12 cm above the exposure glass.
At this time, only the sensor(s) underneath the original receive the reflected light and
switch on. The other sensor(s) are off. The main CPU recognizes the original size
from the on/off signals from the five sensors.
If the copy is made with the ADF open, the main CPU decides the original size from
the sensor outputs when the Start key is pressed.
The above table shows the outputs of the sensors for each original size. This original
size detection method eliminates the necessity for a pre-scan and increases the
machine productivity.
