Color displacement correction processing is performed based on the color displacement correction values stored in service mode
when a job is started.

■ Original Size Detection
● Overview
This machine determines the size of an original by the combination of the measurement results of the reflected light at particular
points of the Reflection Sensor and Reading Sensor. Furthermore, two points are measured for each size to perform accurate
detection even if the original is moved when the ADF is closed.
• Horizontal scanning direction: Reading Sensor (15-point measurement)
• Vertical scanning direction: Reflection Photo Sensor (1 point for AB configuration, 1 point for inch configuration)
The original size is determined using the following procedure:
1. Search of external light (horizontal scanning direction only)
The sensor level at each detection position in the horizontal scanning direction is measured while the LED is OFF.
2. Detection of output level of each sensor
The LED of the Reading Sensor Unit is turned ON to measure the sensor level at each detection position in the horizontal
scanning direction.
Furthermore, the Reflection Photo Sensor LED for the vertical scanning direction is turned ON to measure the sensor output.
The original size is determined by the combination of these outputs.
The detectable sizes differ depending on the country. The country setting can be changed in service mode.
NOTE:
When KSIZE-SW is set for configurations other than inch configuration (including GLOBAL), the original is detected as AB/K
configuration.

● Description of Controls
In horizontal scanning direction, sensor level of each original detection position is measured by moving the Scanner Unit to the
detection position shown in the figure in relation to the original set position. In the vertical scanning direction, the original size is
determined using the Original Size Sensor.
