After the paper is duplicated on HowNet, it will be detected by the system that it has been duplicated. This is because HowNet duplicate checking system has memory function. If it has been detected, the system background will leave a record. This system record is the function of the system itself and cannot be deleted artificially.

If you want to avoid this problem, you can consider the following methods:

Replace the duplicate inspection system: You can choose another duplicate inspection system, such as paperfree. Papertime, etc. Different duplicate checking systems have different databases and algorithms, which can avoid being detected by HowNet system.

Avoid using HowNet to check duplicates: If schools or periodicals do not require using HowNet to check duplicates, you can choose other duplicate checking systems to check duplicates. This can avoid being discovered by HowNet system.
