Even if your document has no accessibility issues in Microsoft or you have followed all the best practices for scanning a document, you still should run the Accessibility Checker in Adobe Pro DC to make sure that the document is accessible as a pdf.
The Accessibility Checker tool is found on the Tools tab in the Protect & Standardize section. Select the Add button to add the tool to your toolbar.
If you have a pdf that was created from a Microsoft program or from a web page, you can now select the Accessibility tool, and from the full menu choose Full Check. If your pdf is from a scan please see the next page for information.
Then in the dialog box that open choose Start Checking.
