Ready signal
Ready for OCR attempt
The file has no usable text layer, scan-quality signals are acceptable, rotation/language concerns are known, and you have a checklist for reviewing names, numbers, and dates.
Quality-gated workflow
Use Scan Rescue when text extraction failed, a PDF appears scanned, or an image contains text that needs review. It helps decide whether OCR is worth running and how to verify output; it does not repair scans or promise recognition accuracy.

Preflight result
Use these signals before running server-backed OCR. Ready means the file is a reasonable OCR candidate with a review plan, not that recognition will be perfect.

Needs review
If the PDF has selectable text or digital text-layer signals, PDF to Text is usually cleaner and cheaper than OCR.
Needs review
Low contrast, rotation, tiny text, blank pages, mixed page sizes, or photo glare should be reviewed before spending a server OCR job.
Needs review
OCR output should be checked against the source for names, totals, punctuation, line breaks, and table structure before reuse.
Task groups
Check for a PDF text layer, scanned-page signals, existing extractable text, page rotation, and image-density clues before launching recognition on a file that may already be digital.
Review scan quality, image contrast, blankness, dimensions, file format, metadata, and language-readiness signals before accepting OCR output as usable.
Use temporary OCR jobs for scanned PDFs or images only after readiness checks make likely quality limits clear, then compare the output before downstream reuse.
If the destination is editable Word, check PDF-to-Word readiness separately because OCR text and editable DOCX conversion are different workflows.
When the output is empty, noisy, or misread, use the OCR path chooser and scanned-document guides before launching another conversion or sending the result onward.
