When you create "text-searchable PDF/XPS/OOXML" files, OCR (Optical Character Recognition) may not be properly processed. This may be because the settings on the machine, or the language, character type or format of the original document are not appropriate for OCR processing.
You can improve OCR processing by customizing the machine settings regarding character recognition according to the documents, or by using suitable character types or fonts in the documents so that the machine can recognize the characters.
