This screen is referred to as the ‘Browse’ screen.  It’s where you select the document you’ve previously scanned in.  It’s also where most mistakes are made.  See under the Browse button where Attachments to Document defaults to No.  If you don’t have software that publishes to a pdf, then the default on Attachments to Document will always stay defaulted to No.  If you only scanned in 1 file, then you will never have ‘attachments.’
	The next 3 screen shots will show how to attach IF YOU USE SOFTWARE THAT PUBLISHES TO PDFS.
