Jovi scan does not have the test paper restoration function. This is because Jovi Scan is an intelligent scanning tool that is mainly used to convert paper documents into electronic files for easy storage and sharing. Its main functions are scanning, cropping, adjusting image quality, etc. to improve scanning effect and readability. However, the test paper restoration function requires more complex image processing and text recognition technology, which can parse the structure and content of the test paper and restore it to an editable electronic document. This is a relatively complex task that usually requires specialized test paper recognition software or OCR (optical character recognition) technology to achieve. Therefore, it is normal that Jovi Scan does not have the test paper restoration function. If you need related functions such as test paper restoration or automatic review, it is recommended to look for specialized test paper recognition software or OCR tools to meet your needs.
