Accessibility, tags, and reflow
Last updated 9/30/2011
“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.
Reading PDFs with reflow and accessibility features
Setting accessibility preferences
Acrobat provides several preferences that help make the reading of PDFs more accessible for visually impaired and
motion-impaired users. These preferences control how PDFs appear on the screen and how they are read by a screen
reader.
Most preferences related to accessibility are available through the Accessibility Setup Assistant, which provides on-
screen instructions for setting these preferences. Some preferences that affect accessibility aren’t available through the
Accessibility Setup Assistant including preferences in the Reading, Forms, and Multimedia categories. You can set all
preferences in the Preferences dialog box.
The names shown for some preferences in the Accessibility Setup Assistant are different from the names for the same
preferences shown in the Preferences dialog box. Acrobat Help uses the names shown in the Preferences dialog box.
For more information about accessibility features, see www.adobe.com/accessibility.
Set accessibility preferences with the Accessibility Setup Assistant
1 Start the Accessibility Setup Assistant by doing one of the following:
• Choose Advanced > Accessibility > Setup Assistant.
• (Windows only) Start Acrobat for the first time while a screen reader or screen magnifier is running.
2 Choose the option that is appropriate for your assistive software and devices.
The assistant presents only preferences that are appropriate for your assistive software and devices, according to the
option that you choose.
3 Follow the on-screen instructions. If you click Cancel at any point, Acrobat uses default settings for the preferences
set by the assistant (not recommended).
