Note
It may be difficult to manually feed a sheet that is unusually thin or that is
curled. It may be necessary to gently hold down the edge of the sheet while
feeding it into the scanner.
4. Perform the scanning operation in accordance with the normal operating
procedure for your application software, and continue to manually feed sheets
into the scanner, one at a time.
Scanning Folio (Folded Documents)
The scanner uses a folio scanning method to scan documents that are bigger
than B4 size paper (maximum A3 size paper). To do folio scanning, fold the
document in half and set it on the scanner, both sides of the folded document
are scanned and are combined as a single image.
