The ADF loads your first document page, then Epson Scan prescans it and displays it in the
Preview window. The ADF then ejects your first page.
Place your first page on top of the rest of the pages, then load the entire document into
the ADF.
In the Preview window, draw a marquee (a line marking the scan area) around the portion
of your document page that you want to scan.
For instructions on creating and adjusting a marquee, see Adjusting the Scan Area
