A number is assigned to each scanned page. The default number is
the number of the last batch page plus one.
You may set page numbers manually if you want to retain the
original page numbers in the document or if you want to scan pages
according to page number.
To specify page numbers:
Select Ask for page number before adding page to the
batch on the Scan/Open tab
(Tools>Options menu).
To scan a
large number of double-sided pages according to page number:
Select Ask for page number before adding page to the
batch on the Scan/Open
tab(Tools>Options).
Specify a number for the first scanned page in the Page
number dialog, then select Odd and even separately in
the Page numbering field. Select an order for the pages:
ascending or descending to reflect the way in which the
double–sided pages have been entered into the automatic document
feeder (i.e. whether the last page or the first page has been
placed on top).
