Optical Character Recognition (OCR) is the function used by computers to read text. This is often saved within DjVu files and is extracted by the computer when a new page inis started in proofreading. However, computers are not very good at reading printed text and errors (sometimes called "scanos") can be quite frequent. This table shows some common errors made by computers that will need to be found and corrected during proofreading.
