I've just purchased a Scanjet 5590 scanner, and am in the process of
scanning masses of paperwork in the house. The scanner scans bundles
of paper using the automatic document feeder to PDF format.

What I would really like to do is bundle lots of different documents
together and insert a blank or separator page between different
documents and then automatically split the generated PDF into
individual document files where the blank / seperator page is found in
the PDF.

Is there any cheap software available (<$100) that will examine a PDF
file and recognise blank pages / separator pages and split the PDF
automatically where these occur? I do not have Adobe Acrobat (too
expensive!) so a plugin for that will not be sufficient.

Scan to PDF is a software <$100 that can achieve exactly what you
need. Here is their web address: http://www.scantopdf.co.uk/
take care and good luck :)

Many thanks for your reply hkharma. I've taken a look at the web-site
and it does seem to be exactly what I need! It seems the Batch
Scanning is handled through a plugin so I have emailed to find out how
much this costs. Thanks VERY much!!
