IMPORTANT
• Selecting [High-Quality Moire Reduction] produces high-
quality images, but the scanning speed is slower.
• If [High-Quality Moire Reduction] is selected, [Auto-detection]
is selected for the document size, the color mode is set to [24-
bit Color], and the scanning side is [Duplex], the scanner may
run out of memory and be unable to scan the entire document.
If this occurs, enable [Speed Priority] and scan images of
lower quality, or set the scanning side to [Simplex].
Image Quality
When the scanning resolution is set to 400 or 600 dpi, you
can enable this setting and select either [Speed Priority] or
[Image Quality Priority].
[Speed priority]
This mode gives priority to scanning speed, and generates
images of 400 or 600 dpi from images scanned at 300 dpi.
[Image quality priority]
This mode gives priority to image quality, and scans at
600 dpi.
When the resolution is set to 400 dpi, images of 400 dpi are
generated from images scanned at 600 dpi.
IMPORTANT
• Selecting [Speed priority] increases the scanning speed, but
the image quality is reduced slightly.
• If [Image quality priority] is selected, [Auto-detection] is
selected for the document size, the color mode is set to [24-bit
Color], and the scanning side is [Duplex], the scanner may run
out of memory and unable to scan the entire document. If this
occurs, enable [Speed priority] and scan images of lower
quality, or set the scanning side to [Simplex].
[Scan Options] (TWAIN driver only)
Specify the operation when scanning continuously with a
TWAIN-compatible application program.
[Standard]
Outputs each scanned page before scanning the next page.
[Scan Ahead]
Scan pages continuously. Scanning speed is faster than
[Standard].
[Scan Single Page]
The [Scanning Side] setting on the [Basic] tab sheet is
changed to [Simplex], and one page is scanned.
[Area] button
Open the [Scan Area] dialog box to specify the area to
scan.
(See “[Scan Area] Dialog Box” on p. 8-11.)
IMPORTANT
The [Area] button is not displayed if the application program
provides its own function to specify the scan area.
