Shading Adjustment
The shading adjustment is used to improve the image quality of the scanned documents. If your final scanned
files are of poor quality, such as perpendicular lines or the image clarity is uneven across the page, you may need
to perform a shading adjustment on the scanner.
To prepare for shading adjustment:
•
Clean the scanner rollers, image sensors, glass and reference plates, as described in the section
Cleaning the
Inside of the Scanner
on page 170.
•
After cleaning the scanner, do a test scan and view the final image file. Do not perform a shading
adjustment until after you clean the scanner and test scan. A shading adjustment performed before cleaning
the scanner may result in degraded image quality.
•
Have the Shading Paper, provided with your scanner, ready as the software will tell you when to insert it into
the scanner.
