♦ [Offset] button
When this button is clicked, the following dialog box is displayed.
Using this dialog box, the offset of the leading edge and magnification for the sub-scanning
direction can be changed.
− Offset Setting:
If the position of the scanned image shifts from the original document, fine adjustment
is possible.
At shipment, the offset has been adjusted to an optimum value within a certain range.
Therefore, adjustment is not generally required.
*The maximum size of changes depends on the device.
− Enable eliminating a dark area on the top of the image.
− Enable eliminating a dark area on the left side of the image.
These modes can be selected to eliminate the dark area on the leading edge and the left
side appeared when using the flat bed
*These functions may not be displayed for some scanner models.
− Vertical magnification Adjustment
The Vertical magnification correction value of sub-scanning direction can be changed.
For ADF scanning, the image is expanded or shrunk in the paper feeding direction
based on the setting value at shipment.
For FB scanning, the image is expanded or shrunk in the direction to which the scan
head moves based on the setting value at shipment.
This function is used to adjust the image whose ratio of length and width seems
different from the original document.
*The setting value varies depending upon the device used.
