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.

Reference:"Scanning an Image from a TWAIN-

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.
