“This document has logical structure but it is not a Tagged PDF. Some accessibility information may be missing.”
Quick Check has found an underlying document structure in the document, so Acrobat will use the available
document structure to control the reading order, rather than analyzing the document itself. However, this untagged
document structure might be incomplete or unreliable, so assistive software and the accessibility features in Acrobat
(such as the Read Out Loud and the Save As Text features) may not read the page properly. If the reading order of the
page seems to be wrong, select Override The Reading Order In Tagged Documents in the Reading panel of the
Preferences dialog box.
“This document is not structured, so the reading order may not be correct. Try different reading orders using the
Reading Preferences panel.”
Quick Check has found no underlying document structure that Acrobat can use for
reading order. Acrobat will analyze the reading order of the document using the current analysis method set in the
Reading Order preference, but this PDF might not be read correctly by screen readers. If the reading order seems
wrong, select a different option for Reading Order in the Reading panel of the Preferences dialog box.
“No accessibility problems were detected in this quick check. Choose the Full Check command to check more
thoroughly.”
Quick Check has found that the PDF contains searchable text, is tagged, has an underlying document
structure, and has no security settings that prohibit access for screen readers. To check for other types of accessibility
problems that may be present in the PDF, use Full Check.
“This document’s security settings prevent access by screen readers.” Quick Check has found that the PDF has
security settings that interfere with screen readers’ ability to extract text for conversion to speech. You may be able to
use a screen reader with this document if your assistive technology product is registered with Adobe as a Trusted
Agent. Contact your assistive technology product vendor.
“This document appears to contain no text. It may be a scanned image.” Quick Check has found that the PDF
contains no searchable text, probably because the document consists entirely of one or more scanned images. This
means that screen readers, Read Out Loud, Reflow view, and most other accessibility features—which rely on text as
input—will not work with this document.
Check accessibility with Full Check
Use Full Check to check a PDF for many of the characteristics of accessible PDFs.
You can choose which kinds of accessibility problems to look for and how you want to view the results.
1 Choose Advanced > Accessibility > Full Check.
2 In the Report and Comment Options section, select options for how you want to view the results.
You can save the results as an HTML file or as comments that are located where the accessibility problems are detected.
3 Select a page range if you prefer to do a full check on individual sections of a document.
When you have a large document, running a full check one section at a time can be more efficient.
4 Select an accessibility standard (Adobe PDF, Section 508 (U.S.), or W3C) from the Name menu, and then select the
accessibility options to check for.
The standard that you select in the Name menu determines which accessibility options are available.
5 Click Start Checking.
