Nothing to configure. The document is checked against the structural requirements a machine can actually verify.

Read the report. It lists what passed, what failed and — importantly — what it did not check at all.
Questions about Check PDF accessibility
- What does it actually check?
- The machine-verifiable parts: whether the document is tagged, whether the language is declared, whether images carry alternative text, whether the reading order exists, whether the title is set. These are the things a checker can prove.
- What can it not check?
- Whether the alternative text is any good. A picture of a chart with alt text saying "image1" passes every automated check and helps nobody. Machines can verify that a description exists; only a person can verify that it describes anything.
- Does passing mean the document is compliant?
- No, and we will not pretend otherwise. It means the structural requirements are met. Real accessibility compliance includes judgements no automated tool can make, and any product telling you a green tick equals compliance is selling you comfort.
