4008 Scanner Sub Scan - Magnification Adjustment
Magnification (image enlargement/reduction) in the sub scan (vertical) direction is
done by adjusting the speed of the scanner motor when the image is scanned.
Adjustment is done relative to the default setting of 100%
• Reducing the setting, increases the speed of the scanner motor and the image is
reduced when it prints.
• Increasing the setting, reduces the speed of the scanner motor and the image is
enlarged when it is printed.
[-0.9 to 0.9/0.0/0.1%]
4010 Scanner Sub Scan
These SP codes adjust sub scan registration to correct skew due to CIS positioning and
variation in CIS sensitivity. The adjustment of the on/off timing of the CIS sensors is done
with the reading of the scanner registration sensor in the scanner unit.
1 Leading Edge Registration Adjustment
This SP shifts the leading edge of the scanned image relative to the sub scan direction.
[-10 to 10/0.0`/ 0.1 mm]
• A higher setting "+" shifts the image down (against the sub scan direction).
• 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]
• A higher setting "+" shifts the image down (against the sub scan direction).
• A lower setting "-" shifts the image up with the sub scan direction).
4011 Scanner Main Scan - Registration Adjustment
This SP shifts the scanned entire image horizontally left or right (in the main scan
direction)
