Appendix 3—Shading Adjustment

What Is the Purpose of Shading Adjustment?

The process whereby variations in the distribution of the scanning lamp's quantity of light are transformed
into a fixed output within the scanning range is known as shading adjustment. Shading adjustment can be
performed using the Trūper User Utility and the special shading paper that is provided with the scanner.

When Is Shading Adjustment Required?

Perform shading adjustment when the density of the scanned images is uneven and the image displays
perpendicular lines, when colors in some parts of the scanned image are extremely different from what is
expected, or when the image quality fails to be improved even after cleaning inside the scanner.
Preparation: Before performing shading adjustment, thoroughly clean the scanner's drive rollers,
reference plates and ADF glass areas. If shading adjustment is carried out while these parts are still dirty, it
will not be possible to eliminate the lines that form on the scanned images. Follow the cleaning procedures

Note
If the scanned images are still lined after shading adjustment has been performed and if these lines
are not eliminated even after the ADF glass areas have been cleaned, it means that the shading has
not been compensated properly. Clean the parts again and perform the shading adjustment
procedure again.
