Image Quality
When 400 or 600 dpi resolution is selected, you can enable this and select
either [Speed Priority] or [Image Quality Priority Image].
[Speed Priority]
This mode gives priority to scanning speed, and generates 400 or 600 dpi
images from images scanned at 300 dpi.
Although scanning speed is fast, image quality is slightly reduced.
[Image Quality Priority]
This mode gives priority to image quality, and scans at 600 dpi.
When 400 dpi resolution is selected, 400 dpi images are generated from
images scanned at 600 dpi.
☞ Scanning with 24-bit Color is disabled when [Image Quality Priority] is
selected. Also, an error may be displayed with some combinations with
other settings, in which case [Speed Priority] should be selected, or other
settings changed.
[Scan Options] (TWAIN driver only)
Specify operation when scanning continuously with a TWAIN-compatible
application.
[Standard image]
Eject a scanned page before scanning the next page.
[Scan Ahead]
Scan pages continuously, so scanning speed is faster than [Standard image].
[Scan Single Page]
The [Scanning Side] setting on the [Basic] tab sheet becomes [Simplex], and
one page is scanned.
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].
[Area] Button
Open the [Scan Area] dialog box to specify the area to scan. (See “[Scan Area]
Dialog Box,” on p. 73.)
The [Area] button is not displayed if the application program provides its own
function to specify scan area.
