Has your company asked you to investigate a way of cutting out the scanning, or is this your idea? I ask because there may be good reasons for the scanning, legal and security ones I mean.
I work for a government agency where we scan every incoming document, and, sure, we could have a lot of them in the form of email attachments, but the IT dept doesn't like the insecurity of that, and we have to scan all the incoming faxes, letters and legal certificates and stuff anyway, and it proves legally that a paper copy actually existed and was witnessed by more than one person. It creates an audit trail. We don't shred our paper copies, we keep them for six weeks and then they go to a file repository.
