Checked repair available
A repaired EPUB download appears when all issues are auto-fixed and the second EPUBCheck run passes.
Download the repaired copy, keep your original EPUB, then retry KDP, Kindle Previewer, or EPUBCheck.
Sample EPUB scan report
See how the live result page changes when a checked repair is ready, blocked by manual decisions, or stopped at a source-export boundary. The point of this page is to show why a download appears, why it does not, and what the next repair path looks like.
Manual decisions blocking repair
Some issues still need a human decision before a checked download is ready.
Use the remaining issue list and the repair summary to fix the source EPUB yourself or keep the details for later edits.
Unsupported by this scanner
Fixed-layout, DRM, image-first, or source-conversion issues are diagnosed but not repaired here.
Use the report paths and error text in your source tool, EPUB editor, or export workflow.
How to read these samples
Same result-page structure
Each sample uses the same live result-page sections: affected paths, original errors, repair decisions, repair log, and next steps.
Checked-download gate
A checked download appears only in the sample state where the written repair passes another EPUBCheck run.
Manual review stays in report mode
When the scanner should not choose the fix, the report stays in explanation mode and keeps a copyable repair summary for your own fix notes.
