ADDITIONAL INFORMATION
When I am scanning on  the  ADF-Duplex I DESIRE to scan ALL  pages  in  ONE Dokument without any other questions to  ONE file like a booklet  or  something like that!
I would also  like to  save this file  in DIFFERENT Formats even after scanning! -  This  would  be great to have PDF and/or  PNG etc.
AND I  would  like to  have these  Options  as DEFAULT!

Thanks a lot  in advance!
