70 Software Setup
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] scanning option is selected in the [Basic] 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.
[Deskew] Check Box
The Deskew function detects slanted document pages and straightens the
scanned images.
☞ The Deskew function does not work properly in the following situations.
Disable Deskew in these cases.
• When scanning a page with a dark area near the edge
• When scanning a glossy or reflective document
• When the brightness setting is incorrect
• When Custom setting is selected in the Gamma Settings dialog box
☞ Note that in other cases, depending on the document, the slant of the image
may not be corrected properly or part of the image may be omitted.
Moire Reduction
When 300 dpi or lower resolution is selected, you can enable Moire reduction
if Moire patterns appear in scanned images.
[None]
No Moire processing is performed.
[High Speed Moire Reduction]
This mode gives priority to scanning speed, and generates images with the
specified resolution from images scanned at 300 dpi. When 300 dpi resolution
is selected, [High-Speed Moire Reduction] is not displayed.
[High Quality Moire Reduction]
This mode gives priority to image quality, and generates images with the
specified resolution from images scanned at 600 dpi.
Although image quality is high, scanning is slow.
When [High Quality Moire Reduction] is selected while Page Size is set to
[Auto-detection], Mode is set to [24-bit Color], and Scanning Side is set to
[Duplex] all at the same time, a portion of the document may not be scanned
due to insufficient memory on the scanner. If this occurs, lower the image
quality by selecting [Speed priority], or change the Scanning Side setting to
[Simplex].
