Selecting the Scan Size
You can scan your images at their original size, or you can reduce or enlarge their size as you scan them. You do this
using the Target Size setting.
If you are going to scan your image to a specific size, you should select the Target Size setting after previewing it, but
before adjusting your scan area indicated by creating a marquee. This sets the scan area to correct proportions so your
image will not be cropped unexpectedly.
To select the scan size, see one of these sections.

Selecting the Scan Size in Home Mode
You can select a predefined scan size from the Target Size list. Click the arrow to open the list and select the size
you want. A marquee (dotted line) proportioned for that size appears on your preview image.
