[gscan2pdf-help] Manual duplex scanning issue

[Victor W. <vw...@wo...>]

I wish to scan part of a book using an epson gt-2500 scanner.

The odd pages (facing) need to be rotated 180 degrees and the even pages 
(reverse) do not. However with the following settings I have a a 
problems concerning rotation of pages which I would like some help with:

Page Options tab/Scan Document window

1. # Pages is set to "#"  and "3" (assume 3 pages for the sake of this 
problem)
2. Source document set to "double sided"
3. Side to scan set to "facing"
4. Post Processing, with Rotate Facing side 180 and Rotate Reverse side 
not checked at all.

I then click on scan and the three facing pages are scanned (and I can 
see they are number 1, 3 and 5

BUT: only pages 1 and 5 are rotated 180 degrees, page 3 is not rotated

I then set the options for the facing pages:

1. # Pages is set to "#"  and "3" (assume 3 pages for the sake of this 
problem)
2. Source document set to "double sided"
3. Side to scan set to "reverse"
4. Post Processing, with Rotate Facing side 180 and Rotate Reverse side  
not checked at all

I then click on scan and the three reverse pages are scanned starting 
with page 6, and they are inserted into the right place, 6 after 5, 4 
after 3 and 2 after 1.

BUT: 2 and 4 are rotated 180 degrees, page 6 is not rotated.

I would be really grateful for help in dealing with the rotating pages 
problem.
