Chapter 8 ISIS/TWAIN Driver Settings

Hint

When the [Scan Options] on the [Basic] tab sheet is set to [Scan Single Page] for the TWAIN driver, the scanning side is set to [Simplex] and cannot be changed. (See “[Scan Options] (TWAIN driver only)” on p. 8-9.)

Selecting [Skip Blank Page] enables the [Setting] button, which opens the [Blank Skip Setting] dialog box.

Adjust the [Content density] setting in the [Blank Skip Setting] dialog box if you specify [Skip Blank Page], but blank pages are not skipped, or if non-blank pages are skipped.

Adjust the content density according to the document content.

When blank pages are not skipped, increase the content density.

When non-blank pages are skipped, reduce the content density.

If the application program provides its own simplex/duplex scanning side setting, select Simplex for this setting.

[Folio]

Documents that are normally folded in half are scanned on both sides and then composed into one image. (See “Folio Scan” on p. 4-7.)

Hint

When [Folio] is not displayed, the batch separation setting on the [Others] tab sheet is set to [Patchcode] (Optional). (See “Batch Separation” on p. 8-20.)

[Deskew] Check Box

The Deskew function detects slanted document pages and straightens the scanned images.

IMPORTANT

The Deskew function does not work properly in the following situations. Disable the Deskew function in these cases.

When scanning a page with a dark area near the edge of the page

When scanning a glossy or reflective document

When the brightness setting is incorrect

When the Custom setting is selected in the Gamma Settings dialog box
