Scanning with the OCR Function

This mode enables you to perform OCR (optical character recognition) to extract data that can be recognized as text from the scanned image and create a PDF/OOXML (pptx/docx) file that is searchable. You can also set <Compact> if you select PDF as the file format.
For information on the optional products required to use this function and the file formats, see System Options.

OCR Results Are Not Satisfactory

When you create text-searchable PDF/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.

Checking the Machine Settings and Supported Languages

You can improve OCR processing by customizing the machine settings regarding character recognition according to the originals, or by using suitable character types or fonts in the originals so that the machine can recognize the characters.
