About Offset and Scale Adjustment
If you click the [Offset] button, the following window appears.
You can change the offset amount of the start position, and the magnification of the sub-scan in
this window.
[Offset Setting]
Fine adjustments can be done if the document position is different from the actual scanning
position.
Generally, there is no need to adjust the setting as it is adjusted to an optimum value at the factory.
*The setting range differs depending on the scanner.
When using the flatbed, you can specify the following modes to delete shadows on top edge and
left edge of the paper.
• "Enable eliminating a dark area on the top of the image" mode
• "Enable eliminating a dark area on the left side of the image" mode
*These modes may not appear depending on the scanner.
[Vertical Magnification Adjustment]
You can change the magnification correction value for sub-scan direction.
In case of ADF, the magnification value for feeding direction can be adjusted based on factory
adjustments.
In case of flatbed, the magnification value for the scanning head movement direction can be
adjusted based on factory adjustments.
(This function is used when the aspect ratio of the generated image looks different from the
scanned document.)
*The adjustable range differs depending on the scanner.
