Adjustment is done relative to the default setting of 100%
• Reducing the setting, increases the speed of the scanner motor and the image is
• Increasing the setting, reduces the speed of the scanner motor and the image is
[-0.9 to 0.9/0.0/0.1%]

• A lower setting "-" shifts the image up (with the sub scan direction).
2 Trailing Edge Registration Adjustment
This SP shifts the trailing edge of the scanned image relative to the sub scan direction.
[-10 to 10/0/0.1 mm]
