Poor Scanning Result

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.
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 the suitable
resolution?
Make sure that the value for the "Resolution" setting in
the scanner driver satisfies the requirement of the set
original.
Reference:
"Professional" Scan Preferences (Main)
CHECK3
Have you specified suitable value for the
"B/W Threshold" setting?
When you scan with "Mono 2 gradation" colour 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 "Professional" screen.

example, too bright output, activate the

Has "Quick Scan" been selected?
If scanning is performed when the "Quick Scan" option
has been selected, image quality may be degraded. This
is because the scanned data is transferred using JPEG
compression. If image quality is poor, then perform
scanning again without selecting the "Quick Scan"
option. ("Quick Scan" is selected by default.)
