Epson Macintosh - Manual (Page 23)

Accessing EPSON TWAIN
To access EPSON TWAIN, choose Acquire (or Place, or the
appropriate command) from the File menu within your
application. You may then have to select
TWAIN (and then
maybe EPSON TWAIN) from a submenu. When TWAIN opens,
you see either the easy or advanced screen, depending on
which was opened last.
The easy screen allows you to select the type, destination, and
document source (if available) of your image. When you scan
with this screen, your entire image is captured and scanned.
The advanced screen lets you select the same basic settings as
the easy screen, plus it allows you to modify, add to, or delete
these settings. The advanced screen also lets you preview and
select the portion of your image you want to scan.
