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 document
glass 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.
Reference:"Scanning an Image from a TWAIN-
Compliant Application" (p.16),
"Scanning an Image from a WIA-Compliant
Application (Windows XP/Vista)" (p.19),
"Scanning an Image from the "Scanner and
Camera Wizard" (Windows XP)" (p.21),
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.

Compliant Application" (p.16)
CHECK4 Have you adjusted the brightness and
contrast suitably?
If you are scanning with a TWAIN-compliant
application and the resulting image has unsuitable
brightness or contrast (for example it is too bright),
activate the "Auto Brightness/Contrast Adjustment"
setting on the "Colour" tab of the "Professional" screen
(p.16).
If you are scanning with a WIA-compliant application
or the "Scanner and Camera Wizard", click "Adjust
the quality of the scanned picture" (p.19) or the
"Custom settings" button (p.21), and adjust th e
brightness and contrast in the screen that appears.
