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.

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.

CHECK 4 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 "Custom settings" 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.

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.
