Selecting the Scan Resolution
In Home Mode, you can change the resolution only if you select Other as the Destination 
setting.
 
In Professional Mode, you can select the resolution you want at any time\
. 
Before you select the scan resolution, you should consider whether you w\
ill enlarge the 
images, and if so, whether you will enlarge them before or after you sca\
n. Follow these 
guidelines:
  
						

							
l     You will not be enlarging the images. 
If you will scan the images at 100% size or smaller and will not enlarge\
 them later, you 
can accept the Resolution setting selected by EPSON Scan based on your o\
riginal and 
destination settings.
 
l     You will enlarge the images as you scan them (increase the Target Size \
setting). 
If you will enlarge the images in EPSON Scan so you can use them at a la\
rger size, you 
can accept the Resolution setting selected by EPSON Scan based on your o\
riginal and 
destination settings.
 
l     You will scan the images at their original size, but then enlarge them l\
ater in 
an image-editing program. 
If you plan to enlarge your images later in an image-editing program, yo\
u need to 
increase the Resolution setting to retain a high image quality after enl\
argement. 
Increase the resolution by the same amount you will increase the image s\
ize. For 
example, if the resolution is 300 dpi (dots per inch), but you will in\
crease the image 
size by 200% in an image-editing program, change the Resolution setting \
to 600 dpi in 
EPSON Scan.
 
Click the arrow next to the Resolution list and select the number of dots per inch at which 
you want to scan. See the table below for some guidelines:
 
What you will do with the 
scanned image
 
Suggested scan resolution 
Send via e-mail, upload to web, view 
only on the screen
 
96 to 150 dpi 
Print, convert to editable text (OCR) 300 dpi 
Fax 200 dpi 
Enlarge after scanning at 100% Increase Resolution setting by same 
amount you will increase image size after 
scanning
 
After selecting the Resolution, you can preview your image and make any \
necessary 
adjustments. See Previewing and Adjusting the Scan Area to continue scanning.
