## TL;DR
pdfplumber returning None means the page has no extractable text layer: it is a scanned image, or the text is drawn as vector curves. Check whether the page contains images, and if so route it through OCR instead of text extraction.

## The error
```text
page.extract_text() returned None
page.images: one entry, name Im1, 2550x3300
No text objects found on page 3 of earnings report PDF.
```

## Fix it
1. Inspect the page object: check page.images and page.chars. Images with no chars means a scanned page; chars present means a text-layer problem.
   Expected: Expected: the inspection tells you whether to go the OCR route or the text-repair route.
2. For scanned pages, render the page to an image with page.to_image and run OCR (tesseract or a cloud vision API) on it.
   Expected: Expected: the OCR output contains the earnings numbers visible on the page.
3. For pages with chars but None text, the PDF may use a custom encoding. Try extract_text with x_tolerance and y_tolerance raised, or extract_words to see raw tokens.
   Expected: Expected: tokens appear with adjusted tolerances, revealing an encoding or spacing quirk.
4. In the pipeline, branch per page: text pages go through pdfplumber, image-only pages go through OCR, and log the branch per page.
   Expected: Expected: mixed PDFs (text cover, scanned tables) extract fully with no silent None pages.

## When to use
- Your earnings report extraction silently drops pages because extract_text returns None.
- You need to distinguish scanned pages from broken text layers.
- You process mixed PDFs where some pages are images and some are text.

## When not to use
- extract_text returns garbled text instead of None - that is an encoding issue, different fix.
- Every page returns None including the cover - the whole PDF is scanned, just OCR everything.
- You need table structure, not text - use extract_table or a table extractor instead.

## Why it happens
PDF is a drawing format, not a text format. Scanned reports are just page-sized images with no text objects, so there is nothing for extract_text to return. Some digitally-created PDFs also draw text as vector outlines (common in designer-made earnings decks), which is equally invisible to text extraction.

## Variant phrasings
### pdfplumber extract_text returns None
Same failure and fix; some searchers phrase the query this way.
### pdfplumber no text extracted scanned pdf
Same failure and fix; some searchers phrase the query this way.

## Edge cases
- A page can have both a text layer and a scanned image (OCR'd PDFs); extract_text may return the OCR layer with errors.
- Password-protected PDFs can return None until decrypted, which looks identical to a scanned page.
