4 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 original table 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,

Scanning an Image from a WIA-Compliant

Application (Windows XP),

Scanning an Image from the "Scanner and

Camera Wizard" (Windows XP),

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 Contrast/Brightness Adjustment" setting on the "Main" tab of the "Professional" screen. Click the "Brightness/Contrast" button to adjust the brightness and the contrast viewing the scanned output image on the screen.

If you are scanning with a WIA-compliant application or the "Scanner and Camera Wizard", click "Adjust the quality of the scanned picture" or the "Custom settings" button, and adjust the brightness and contrast in the screen that appears.

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

If part of the image from the back side of the original appears in the preview scan.

If you are using a TWAIN-compliant application and the back side of the original appears faintly in the preview image, try adjusting the Brightness and Contrast settings. Click the "Brightness/Contrast" button in the Preview screen to change to the Brightness/Contrast screen, and adjust the "Brightness" and "Contrast" values. A preview of the image using the new values appears under "After". When the image of the back side disappears and you can get only the needed image, click the "Apply" button to apply the new settings, and then click the "Scanning" button to scan the image.
