Area
Select the area to be scanned. Area settings here are overridden in the following
cases:
When [Auto-detection] is selected from the Page Size drop-down list
When [Text Orientation Recognition] is enabled in the [Image processing]
tab
When [Deskew] is enabled in the [Basic] tab, the specified area may be
displaced when scanning.
Area Window
The size indicated for the Area window corresponds to the page size setting,
and the area within the panel indicates the current scanning area.
The scanning area can be adjusted by dragging the handles bordering the
Area window with your mouse.
When you use CapturePerfect, the last scanned image appears in the Area
window.
Margin
This control adjusts the top, bottom, left, and right margins around the
scanning area so that you can expand the scanning area to include the edges of
a document, or reduce it to avoid black frames around scanned images.
If the edges of documents are missing from scanned images, move the
slider to the right to expand the scanning area.
To eliminate the black frame around scanned images, reduce the scanning
area by moving the slider to the left.
The measurement units for margins are determined by the Unit setting.
Preview Button (TWAIN driver only)
Click [Preview] to scan one document page and display its preview image in the
Area window.
