Book Processing Warning

Some PDFs use fonts that Pozotron has trouble recognizing. There are a few fixes to get your project reset and working correctly.


How to fix a PDF error with Optical Character Recognition (OCR)

Occasionally a PDF manuscript uploaded into Pozotron Studio will show up with missing text, distorted text, or symbols in place of certain letters.

An error in the PDF document causes this issue. Either the pdf is locked for editing or another setting is preventing Pozotron’s PDF parser from reading it properly.


Most pdf manuscripts with OCR errors will show the following error message:

OCR error message

Users can test this by highlighting some text in the PDF, copying it, and pasting it into Notepad or Microsoft Word.

It will not paste correctly, showing the same missing/distorted text or symbols in place of letters.


To resolve an OCR issue with a PDF script, follow the steps below or watch this how-to video:

  1. If you have the script in a different format (e.g. .docx), please upload that version into Pozotron by creating a new project.
  2. Run your original PDF through an OCR software, and reupload them into Pozotron by creating a new project. Here are two resources you can follow to do this through Adobe Acrobat or Google Drive

If the steps above do not resolve your issue, please contact the Pozotron Support Team at
