Chapter 7 ISIS/TWAIN Driver Settings

Dots per inch

Select the scanning resolution.

☞Higher resolutions provide clearer images, but produce larger files.

☞When the selected resolution is 300 dpi or less, the [Moire Reduction] setting is enabled to allow reduction of Moire patterns in scanned images.

☞When the selected resolution is 400 or 600 dpi, the [Image Quality] setting is enabled.

Scanning Side

Select which page side(s) to scan.

[Simplex]

Scan only the front (top) side of documents loaded at the feeder inlet.

[Duplex]

Scan 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.

☞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 blank pages are not skipped, or if non-blank pages are skipped.

The Content density should be adjusted according to document content, so that only blank pages are skipped: increase the setting if they are not skipped, and decrease the setting if non-blank pages are skipped.

☞The Skip Blank Pages function may not work properly if the [Custom] setting is enabled in the Gamma Settings dialog box.

☞When the [Scan Single Page] feeding option is selected in the [Others] tab sheet of the TWAIN driver, the [Simplex] scanning side setting is selected automatically.

☞If the application program provides its own simplex/duplex scanning side setting, select Simplex in this dialog box.
