Selecting the Scan Size 
						

							
You can scan your images at their original size, or you can reduce or en\
large their size as you 
scan them. You do this using the Target Size setting in Home or Professi\
onal Mode.
 
Home Mode 
Professional Mode  
						

							
If you are going to scan your image to a particular size, you should sel\
ect the Target Size 
setting after previewing it, but before adjusting your scan area (indic\
ated by the marquee). 
This sets the scan area to the correct proportions so your image will no\
t be cropped 
unexpectedly. 
For instructions on previewing your image(s), see Previewing and Adjusting the Scan Area. 
Then follow these steps to select the Target Size setting:
 
You can choose a predefined scan size from the Target Size list. Click t\
he arrow in the 
list and select the size you want. A marquee (dotted line) proportione\
d for that size 
appears on your preview image:  
						

							
If you need to create a scan size that is not in the Target Size list, y\
ou can create a 
custom size. Click the arrow in the list and select Customize. You see the Target Size 
window:
 
Type a name for your custom size, enter the size, click the Save button, then click OK. 
Your new size appears in the Target Size list.
 
In Professional Mode, you can fine-tune the size using additional tools.\
 Click the + 
(Windows) or 
 (Mac OS X) next to Target Size to display these tools:  
						

							
l     To size your image by a certain percentage, adjust the Scale value. 
l     To change the way your image is cropped, turn Trimming on or off. (See EPSON 
Scan Help for details.)
 
l     To unlock the proportions of your scan size, click the  lock icon. Then adjust the 
marquee or enter new width/height measurements.
 
Once you have selected your scan size, you can click and drag the marque\
e to the 
area in the image you want to scan. For details, see Adjusting the Scan Area 
(Marquee). The marquee proportions are retained as you adjust it.
 
If you need to rotate the marquee for a landscape or portrait image, cli\
ck the 
 orientation icon. (Not available if you are scanning at the Original Target Size.) 
 
Note:
For more information about using the Target Size tools, click Help in the EPSON 
Scan window.
 
Now you are ready to scan your image(s). See Finishing the Scan for

Finishing the Scan 
						

							
When you have finished selecting scan settings, you are ready to scan. C\
lick the Scan button. 
After a few moments, your images are scanned.

you see the 
File Save Settings window. This lets you select the name and location of\
 your saved 
scan files. See Selecting File Save Settings for details.
 
l     If you started your scan from a scanning program such as Adobe Acrobat, \
your 
scanned image(s) open in the program window. Click Close to close the EPSON Scan 
window and view your image(s) in the program.
