What this issue means
A deliberate blank page can be correct. The rule distinguishes isolated layout blanks from consecutive runs and records where the run begins and ends.
What BookPreflight checks
- Consecutive blank-page counts
- Beginning, interior and ending locations
- Visible marks or hidden content preventing a page from being truly blank
How to correct the source file
- 1
Confirm intentional blanks in the source layout.
- 2
Remove accidental trailing or duplicated pages.
- 3
Re-export and verify the final page count used by the cover.
Verify the exported PDF, not the preset name
Keep the editable source and original PDF. Export a new file, run the complete scan again and review every remaining finding. A repair is only labelled safe after loss checks and a full deterministic post-flight.
