Text Is Not OCR Processed Correctly

Text may not be OCR processed correctly when creating a text-searchable file. In this case, check whether the language setting for OCR processing and the original being used are appropriate.
You can change the language setting according to the original and improve the processing accuracy by using an original with a character type and font recognizable by the machine and using an original suitable for OCR processing.

IMPORTANT

When OCR Processing Is Not Performed Correctly Even with an Appropriate Language Setting and Original

The processing accuracy may not be able to be improved for originals with a large volume of text per page.

Note the following when creating a Word-format OOXML file:

The text may be replaced with unintended characters or characters may be missing depending on the background color, font, font size, italicization, and other factors.

Paragraphs, line breaks, and tables are not reproduced.

Some images such as diagrams, photos, and seals may be recognized as text and replaced with text.
