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.
CHECK 1 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 document
glass is also clean.
CHECK 2 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.

Camera Wizard" (Windows XP),
CHECK 3 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 "Custom Settings" screen.
