Are there any diagnostic tools or software that can help troubleshoot the P02 error on a Canon MP287?

While official Canon diagnostic tools for end-users are limited, some unofficial service software exists that claims to be able to reset the waste ink counter or diagnose certain errors on Canon printers, including models like the MP287. However, using such software comes with risks, including potentially voiding warranties or causing further software corruption if not used correctly. It's a path often explored by advanced users but not generally recommended for beginners.
