Mode

Select the mode for scanned images.

Hint

•Advanced text enhancement modes are good for scanning documents with a background color or design behind text as black and white images, and remove or process the surrounding background to enhance the text for easy reading. Two advanced text enhancement modes are provided to suit different background types. Select the mode that seems to best suit your document. We recommend confirming an image by prescanning the first page.

•When saving an image file in JPEG format, select [256-level Gray] or [24-bit Color].

[Black and White]

Use this mode to scan text and line drawing documents as black and while (binary) images.

[Error Diffusion]

Use this mode to scan documents containing photos as black and white (binary) images.

[Advanced Text Enhancement]

Use this mode to scan documents with a dark or nonuniform (pattern) background.

Hint

•If the background is uniform, it is removed where it surrounds the text.

•If the background is non-uniform, such as a pattern, it is processed to enhance text readability.

[Advanced Text Enhancement II]

Use this mode to scan documents with a light uniform background and low-contrast text.

Hint

•The background in tight spaces around text may not be removed.

•Documents with low-contrast text can be made more readable by adjusting the contrast.

•If the background is non-uniform, such as a pattern, the background remains visible in the image, and text may be hard to read.

[256-level Gray]

Scans documents such as photos as grayscale images.

[24-bit Color]

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