9.3 Shading Adjustment
When shading adjustment is required
•
Perform shading adjustment when the density and brightness of sections of scanned images are
considerably uneven, or when image quality does not improve after cleaning the inside of the scanner.
Before proceeding with the shading adjustment
•
Before beginning shading adjustment, thoroughly clean the scanning glasses, reference area (page 41),
and all rollers (page 42).
If you perform shading adjustment while these parts are dirty, lines will appear on scanned images.
Shading adjustment procedure
1.
Start User Utility.
2.
Click [User Shading] on the main menu, and operate as the image display dictates.
Note
•
For further details, refer to section [User Shading] in the help for User Utility.
Notice
•
If the shading adjustment has not been performed properly, then lines might appear on scanned
images even after adjusting the shading, or lines might not be eliminated even after cleaning the
scanning glass. Clean the parts, and then adjust the shading again.
