Paper based documents are scanned using whatever scanner and whatever capture scanning software that you currently have installed (or will have installed if a new installation).  Once the paper documents are transferred into a scanned image file, then documentINDEXER+ will "capture from folder" the scanned documents and process them according to the rules set up in the workflow for that document type. 

The scanned documents are best first scanned to the designated "watch" folder in a TIF file format (of course it can process other file formats than just TIF - 134 different file formats). This is true especially if there is any OCR (Optical Character Read) process to occur. If the files are PDF, they can be converted to TIF for the OCR process and then published to the repository (storage Windows based file folder location) once again in a PDF file format. The "watch" folder that documentINDEXER+ monitors is usually on the hard drive of the PC that is connected to the scanner.
