If you get poor quality as a result of scanning job, and you cannot improve the quality by changing preferences,
refer to the check list shown below.

Check your original before scanning. If any dust sticks
to the original, you cannot obtain a clean result. In
addition, make sure that the original table is also clean.

resolution?

CHECK3 Have you specified suitable value for the
"B/W Threshold" setting?

"B/W Threshold" setting. A larger threshold value
makes your output darker, whilst a small threshold
value makes it lighter. To adjust the threshold
automatically, click the "Auto Threshold" button on the
"Image" tab of "Professional" screen.
