Detecting Text on a Scanned Document
Step 1: First, it would be a good idea to make sure the scanned image is perfectly aligned.
Go to Document > Optimize Scanned PDF; click on the Defaults button in the lower left corner, and click ok.
Now you're ready to detect the text.
Step 2: Go to Document > OCR Text Recognition > Recognize Text Using OCR... Select All Pages and click ok.
* If there is still some text that is not able to be selected, repeat step 2.
Step 1: Go to Document > Extract Pages; check the box labeled Extract Pages As Separate Files and click ok.
Step 2: Select where you want the extracted pages to be saved. The extracted pages will be saved as file name 1, file name 2, etc.
