OCRed PDF documents downloaded from library publishers might have limitations that prevent the documents from meeting accessibility standards and create compliance risks.

How to Avoid / Fix: OCR is a significant accessibility improvement for PDFs, but poorly-OCRed text is still often difficult to read. If the latest version of PDF has been downloaded from the library publisher and accessibility issues persist, contact CDE cdesupport@uta.edu and angela.morse@uta.edu, Library Assistant Director of Acquisitions, and provide the course name and attach the PDF for review.

Canvas pages sometimes contain leftover fragments of deleted content. This occurs when links, headings, or design elements (such as text blocks, images, tables) are removed but not fully deleted. These remnants can lead to broken links, incorrect headings, and formatting issues across any Canvas item that uses the Rich Text Editor, including quizzes, assignments, announcements, and pages.

How to Avoid/Fix this Issue: To delete a link while editing a Canvas page, click on the link you want to remove. A pop-up menu will appear with options to edit or remove the link. Select “Remove Link”, which will convert the link back to regular text. Once the link is removed, you can delete the text if it is no longer needed. If the issue persists, contact CDE: cdesupport@uta.edu
