If you’ve scanned documents to PDF format, they may need to be OCR'd (Optical Character Recognition) in order to be readable. A scan may produce a PDF that is actually an image that contains text that is not readable. OrbitDoc will show when a PDF doesn't have accessible text:
This means that the text in the PDF is inaccessible and cannot be read or selected using the OrbitDoc toolbar. The PDF will need to be scanned in order to make the text readable.
We have a Chrome app called Snapverter that is used for converting files to be accessible. A trial version of Snapverter is available Chrome Web Store.
(Note: Some publishers secure their content where they may not be allowed to be converted. In this case you will have to contact the publisher to see if they have an accessible version of the publication)
