Compare the machine manual version I downloaded yesterday to the one our system shows and tell me whether the tolerances I used are still valid for this serial range. I have the unit serial, the sticker revision, and my measurements. Explain any discrepancy in plain language, state whether my current repair tolerances are acceptable, and recommend whether I should stop, remeasure, or proceed as-is.
when the reply comes backPush once: ask it to sharpen the weakest part, and to say what it assumed.

  6. 6

    To change the reading order, select a content area and adjust its order number as needed.

  7. 7

    If necessary, use the options to split, merge, or reassign content areas to ensure logical reading sequence.

  8. 8

    After making changes, review the order visually to confirm it matches the intended logical flow.

FAQ

about this task

PDF/UA is a specific standard just for PDF documents. WCAG (Web Content Accessibility Guidelines) is a set of rules for making all kinds of web content accessible, not just PDFs. Often, regulated work needs to follow both standards to be fully compliant, as they cover different aspects of accessibility.

  1. After auto-tagging, go to 'All tools' > 'Prepare for accessibility'.
  2. Select the 'Reading Order' tool.
  3. Visually check the numbered boxes on your page to ensure they follow a logical flow.
  4. Drag and drop boxes or change their order if needed to fix the sequence.

It is much better to fix accessibility problems in the original document (like a Word file) before you make it a PDF. When you fix the source, the PDF you create from it will often be accessible from the start. This saves a lot of time and effort compared to fixing a PDF after it has already been made, which can be a very long process.

Yes, the PDF Accessibility Auto-Tag API is designed to work with both native PDFs (created digitally) and scanned PDFs. It uses smart technology to identify headings, tables, lists, and paragraphs, and it also recognizes the language, making scanned documents more accessible.

Alt text, or alternative text, is a short description of an image or graphic in your PDF. It matters because screen readers use this text to tell visually impaired users what the image is about. Without alt text, these users would not understand the visual content, making the PDF less accessible.
