Enter the value to adjust the position of image leading edge.
Setting range: 1 – 100 (changing the value by 10 moves the position by 1mm)
Original size detection
Original size is identi
fi
ed based on the result combinations of re
fl
ection light at the speci
fi
c
point on the re
fl
ection sensor and the scanner unit. To prevent the original from moving when
closing the DADF, there is 2 point original size detection per each size on the scanner unit.
In main scanning direction: scanner unit (AB type: 9 point measurement, Inch type: 6 point
measurement)
In sub scanning direction: re
fl
ection type photo sensor (AB type: 1 point, Inch type: 1 point)
Original size is detected in the following procedure.
1) External light search (in main scanning direction only)
While keeping the LED lamp unit OFF, the CMOS sensor level of each detection point is
measured in main scanning direction.
2) Output level detection of each sensor
While keeping the LED lamp unit ON, CMOS sensor level of each detection point is
measured in main scanning direction.
The machine turns ON the LED of re
fl
ection type photo sensor in sub scanning direction and
measures the sensor output.
Original size is identi
fi
ed by these output combination.
