IMPORTANT
- Do not apply these functions to images without moire, dust/scratches or faded colors. The color tone may be adversely affected.

NOTE
- Selectable settings depend on color mode settings.
- Scanning may take longer when you use Image Settings.
Image Settings allows you to set the following items:
When Image Adjustment is set, the brightness of the specified portion of the image is optimized. Images can be adjusted according to the automatically detected document type or the specified document type. The result of the adjustment will be reflected in the entire image.
- None
Image Adjustment will not be applied.
- Auto
Applies Image Adjustment by automatically detecting the document type. It is recommended that you normally select this setting.
- Photo
Applies Image Adjustment suitable for photos.
- Magazine
Applies Image Adjustment suitable for magazines.
- Newspaper
Applies Image Adjustment suitable for newspapers.
- Document
Applies Image Adjustment suitable for text documents.
IMPORTANT
- You can set Image Adjustment after preview.
- You can set this setting when Recommended is selected on the Color Settings tab of the Preferences dialog box.
NOTE
- If the image is not adjusted properly with Auto, specify the document type.
- The color tone may change from the source image due to the Image Adjustment. In that case, set Image Adjustment to None.
When this is set to ON, the outline of the subjects is emphasized to sharpen the image.
Printed photos and pictures are displayed as a collection of fine dots. "Moire" is a phenomenon where uneven gradation or a stripe pattern appears when such photos or pictures printed with fine dots are scanned. Descreen is the function for reducing this moire effect.
NOTE
- Even if Descreen is set to ON, some moire effects may remain if Unsharp Mask is set to ON. In that case, set Unsharp Mask to OFF.
- Selecting Magazine(Color) in Select Source on the Basic Mode tab has the same effect as setting Descreen to ON on the Advanced Mode tab.
Scanned photos may contain white dots caused by dust or scratches. Use this function to reduce such noise.
- None
Dust and scratches will not be reduced.
- Low
Select this to reduce small dust particles and scratches. Large ones may remain.
- Medium
It is recommended that you normally select this setting.
- High
Select this to reduce small/large dust particles and scratches. Evidence of the reduction process may remain and may also remove delicate parts of the image.
IMPORTANT
This function may not be effective for some types of photos.
NOTE
It is recommended that you select None when scanning printed materials.
Use this function to correct photos that have faded with time or have a colorcast. "Colorcast" is a phenomenon where a specific color affects the entire picture due to the weather or ambient strong colors.

- Medium
It is recommended that you normally select this setting.

- You can set this setting when Recommended is selected on the Color Settings tab of the Preferences dialog box.
- Fading Correction may not be effective if the scan area is too small.
Use this function to reduce graininess (roughness) in photos taken with high-speed or sensitized film.
- None
Graininess will not be reduced.

When you change the Backlight Correction setting, the result will be reflected in the preview image.

IMPORTANT
- Do not place items that weigh 4.4 lbs (2.0 kg) or more on the Platen. Also, do not press on the document with a force exceeding 4.4 lbs (2.0 kg). If you press heavily, the scanner may not work correctly or you might break the glass.
- Align the document with the edge of the Platen. If not, the shadow will not be corrected properly.
- Shadows may not be corrected properly depending on the document. If the page background is not white, shadows may not be detected correctly or may not be detected at all.
- While scanning, press down on the spine with the same amount of pressure you used to preview the scan. If the binding part is not even, the shadow will not be corrected properly.
How to place the document depends on your model and the document to be scanned.
NOTE
- Cover the document with black cloth if white spots, streaks, or colored patterns appear in scan results due to ambient light entering between the document and the Platen.
- If the shadow is not corrected properly, adjust the cropping frame on the preview image.
