Shading Adjustment
¥What is the purpose of  the shading adjustment?
The shading adjustment function corrects variations in the lamp intensity and pixel sensor sensitivity, and reduces
unevenness in density in scanned images. It can be carr ied out by means of the User Utility using the special
shading paper, which is provided with this scanner.
¥ When shading adjustment is required
Proceed with the compensation when the colors in some parts of the scanned images differ in the extreme, or when
the image quality fails to be improved even after the inside the scanner is cleaned.
¥Before proceeding with  the shading adjustment
Before proceeding, be absolutely sure to thoroughly cl ean the ADF glass (F) area, ADF glass (B) area, reference
plate (F) and reference plate (B) as well as the tr ansport path and drive rollers of the scanning unit.
If the shading adjustment is ca rried out while these parts are still dirty, it will not be po ssible to eliminate the lines that
form on the scanned images.
¥ Shading adjustment procedure
1. Start the User Utility.
2. Click “User Shading” on the main menu , and operate as the image display dictates. For further details, refer to 
section 4.6 in the User Utility Reference Manual.
¥ Caution
If the scanned images are still lined a fter the shading adjustment has been per formed 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 then proceed with the shading adjustment.
