Chapter 8 ISIS/TWAIN Driver Settings

■[Basic] Tab Sheet Settings

You can configure the following settings on the [Basic] tab sheet.

User Preference

Click [Save] to open the [Save User Preference] dialog box.

The [Save User Preference] dialog box saves the current settings under an assigned name.

You can select the name of a saved set of user preferences in the list box to load those settings into each tab sheet.

IMPORTANT

Assigned names can consist of up to 32 characters (or 16 double-byte characters).

Mode

Select the mode for scanned images.

Hint

•Some functionality is limited depending on the mode setting. (See “Mode-Dependent Function Limitations” on p. 8-10 and “[Brightness] Tab Sheet” on p. 8-12.)

•Advanced text enhancement modes are useful if you want to scan documents with a background color or design behind the 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 best suits your document. We recommend confirming the 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]

This mode is displayed when the resolution is 300 dpi or lower, and is good for scanning documents with uniform background colors or light text and backgrounds.

Hint

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

•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 as a pattern, the background remains visible in the image, and text may be difficult to read.

[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.
