Saving Scanned Documents as a Searchable PDF Using Epson Scan 2
You can scan a document and save the text in a searchable PDF. In a searchable PDF, text is
recognized using Optical Character Recognition (OCR) and then embedded in the scanned original.
Note: The required Epson Scan 2 OCR Component Pro is installed automatically when you install your
product software as instructed on the Start Here sheet. If you install your scanner software programs
individually, be sure to also install this component using the Epson Software Updater if you want to
perform OCR.
