Poor Scanning Result
If you get poor quality as a result of scanning a job, and you cannot improve the quality by changing preferences, refer
to the check list shown below.
CHECK1
Is the original clean?
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.
CHECK2
Have you specified a suitable resolution?
Make sure that the value for the "Resolution" setting
in the scanner driver satisfies the requirement of the
set original.

CHECK3
Have you specified a suitable value for the "B/
W Threshold" setting?
If you are scanning with a TWAIN-compliant
application and are using "Mono 2 gradation (no
Green)","Mono 2 gradation (no Red)" or "Mono 2
gradation (no Blue)" mode, make sure that a
suitable value is specified for the "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
the "Professional" screen.
