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.
