Canon Service Tool v5204 (ST v5204) is a Windows-based maintenance/reset utility widely circulated in repair communities since about mid-2018. It’s used to place supported Canon inkjet printers into service mode, read/write EEPROM, reset waste-ink (absorber) counters, run various maintenance operations (cleaning cycles, platen/chassis movements), and dump or restore firmware-related values. The tool is not an official consumer download from Canon; distributions are typically packaged and redistributed by third parties, sold on small webshops, shared on forums, or hosted on file-sharing links.
