This dialog box appears with application programs that display the [Scan] 
button in the Properties dialog box.

The Area window and [Preview] button are not displayed when using 
applications like the Job Registration Tool that display the [OK] button in the 
Properties dialog box.

This setting is linked to the [Page Size] setting, for selecting the size of 
document pages to scan. Clicking the [Custom] button opens the [Custom Page 
Size] dialog box, where non-standard page sizes can be registered as custom 
page sizes.

Select the area to be scanned.
→ Area settings here are overridden in the following cases:

y When the [Auto-detection] page size is selected
y When [Text Orientation Recognition] is enabled on the [Image processing] 

tab sheet

→ When [Deskew] is enabled on the [Basic] tab sheet, the specified area may 

be displaced when scanning.

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.
→ With CapturePerfect, the last scanned image appears in the Area window.

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. 

Click the [Preview] button to scan one document page and display its preview 
image in the Area window.
