Using the Canon Service Tool v4720 to reset a printer you own is generally legal in most countries under "right to repair" laws. However, Canon does not endorse it. The tool is copyrighted, and distributing it may violate Canon’s EULA. That said, thousands of users have safely used it without legal repercussions.
If your printer is under warranty, resetting the waste ink counter will void the warranty. But most printers trigger this error long after the warranty expires—Canon’s planned obsolescence in action.
