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
