The Service Tool V4720 is a portable, unofficial utility created for Canon inkjet printers. Its primary function is to communicate with a printer while it is in "Service Mode" to perform critical maintenance tasks. The most common use is resetting the printer's to clear the waste ink counter, effectively reviving a printer that has been locked due to the "5B00" error. The tool is often simply referred to as "ST.4720".
Using the Service Tool carries risks. If you use the wrong version or attempt to reset the printer incorrectly, you can "lock" the service mode permanently, requiring a physical replacement of the motherboard's EEPROM chip. Furthermore, resetting the counter does not physically clean the ink pads; you should eventually replace or wash them to prevent actual ink leakage. AI responses may include mistakes. Learn more
