I cannot select a paper size when crating a PDF from the scanner. The preference menu will only provide "automatic" as a selection and the scanner scans 8X14. I Adobe Acrobat 8 I could hide scanner native option. Not possible in 9.
I have figured out how to get around this scanner problem. I went to Create PDf>Scanner>Custom Scan. Then under Scanner Options>Native mode> User Interface, I selected "Show scanner's native interface". This brought up the normal menus I had in Adobe Professional 8. Seems to work now. Could not find this in any of the documentation. Can't figure out why 8.5X11 isn't the default page size.
