When you create a PDF using the PDF From Scanner command in Acrobat, the error "Bad Parameter" appears and no PDF is created.
In the Configure Presets dialog, choose the scanner attached to your computer from the Scanner pop-up menu.
Note: Some older scanners do not support presets. When you choose an unsupported scanner from the pop-up menu, a dialog stating "This scanner does not support presets" appears.
When you try to delete a page from a PDF, you see the error message “Bad Parameter.” The same error message may also occur when you try to insert or add a page to the PDF.
The “Bad Parameter” error occurs when Acrobat finds some problem with the underlying structure of the tags in the PDF file. Try the solutions mentioned in the article: Error: Bad Parameter while deleting pages in Acrobat
