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/Vista),

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.

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 "Color" tab of the

screen.

If you are scanning with a WIA-compliant

application or the "Scanner and Camera Wizard",
