☞ Documents with low-contrast text can be made more readable by adjusting Contrast on the

[Brightness] tab sheet.

☞ If the background is non-uniform, such a pattern, the background remains visible in the image,

and text may be hard to read.

[High-Speed Text Enhancement]

This mode optimizes processing speed by performing background processing within the scanner,

and is good for scanning documents with light background and dark text.
☞ If the text and background in a document have nearly the same density, the text may be hard to

read.

☞ Areas with uniform background may appear as non-uniform white in the image.
☞ Because background processing is performed within the scanner, scanned images are more

susceptible to lines appearing due to dirt on the scanning table glass. In cases where this may be

a problem, try scanning again after cleaning the scanner glass, or select one of the [Advanced

Text Enhancement] or [Advanced Text Enhancement II] modes instead.

[256-level Gray]

Scans documents such as photos as 256-level grayscale images.

[24-bit Color]

Scans documents such as color photos as full-color images.

[Auto Color Detection]

Whether a document is black and white or color is detected before the scanned image is saved.
☞ When [Auto Color Detection] is enabled, the [Setting] button is enabled for opening the [Auto

Color Detection] dialog box, where you can make settings affecting how color documents are

judged, and select which scanning mode to use for black and white.

☞ Depending on the application program, operation may become unstable when [Auto Color

Detection] is enabled. In that case, [Auto Color Detection] should be disabled.

☞ When using an application that supports the MultiStream function (such as CapturePerfect), if

[Auto Color Detection] is selected, the MultiStream function is disabled.
