Chapter 8 ISIS/TWAIN Driver Settings
Dots per inch
Select the scanning resolution.
Hint
• Higher resolutions provide clearer images, but produce larger
files.
• The [Moire Reduction] setting is enabled when the resolution
is set to 300 dpi or lower, and the [Image Quality] setting is
enabled when the resolution is set to 400 or 600 dpi.
• The [Advanced Text Enhancement II] mode cannot be used
when the resolution is set to 400 or 600 dpi.
Scanning Side
Select which page side(s) to scan.
[Simplex]
Scans the front side (top) of documents.
[Duplex]
Scans both sides of documents.
[Skip blank page]
As each document page is scanned, its scanned image is
judged as to whether it is blank, and if so, the image is not
saved.
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.
(TWAIN driver only)” on p. 8-10.)
• Selecting [Skip blank page] enables the [Setting] button,
which opens the [BlankSkip Setting] dialog box.
• Adjust the [Content density] setting in the [BlankSkip 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.
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
