Sometimes, when you have to scan a large number of documents at once, the step of doing OCR (making the PDF searchable) after each document can really slow things down. It may be preferable to scan them all in and then OCR them all in one big shot.
The problem is that in the default setup, each scan is OCRed right after the scan and depending on the age your machine (my G5 is getting a little long in the tooth) in can take quite a while. When you’re in the process of scanning many hundred’s of pages of paper documents, you don’t want to have to wait for the computer to do it’s OCR recognition, you’d rather feed it all the documents and let it do OCR while you’re doing something else.
Fortunately, this is possible. Reading all the way through the handbook as well as through the ABBYY online help I found out that you can scan to PDF only, and then afterwards convert the PDFs with ABBYY FineReader.
