Frequently Asked Questions
Why does the 'Incorrect PDF Structure' error occur in Acrobat?
This error is typically caused by a software bug in specific versions of Adobe Acrobat or by conflicting hidden accessibility tags generated by certain hardware scanners when creating the PDF.
Can I fix the PDF structure error without updating Acrobat?
Yes. If you cannot update your software, you can often bypass the error by opening the Tags navigation pane (View > Show/Hide > Navigation Panes > Tags) and deleting the document's root tags before attempting to save or modify pages.
Does deleting PDF tags affect my document's content?
No, deleting tags does not alter the visible text or images in your document. However, it will remove structural information used by screen readers, which affects document accessibility for visually impaired users.
What if updating Acrobat and removing tags doesn't work?
If the issue persists, you may need to recreate the PDF by selecting 'Print' and choosing 'Microsoft Print to PDF' (or similar virtual printer) to strip problematic metadata, or use an alternative PDF editor like WPS Office to modify the pages.
