The Canon Service Tool (also known as the "ST tool" or "Adjustment Program") is a proprietary software application developed by Canon exclusively for authorized service centers. It is intended for public distribution. Version V5610 is one of many iterations designed to interface with the EEPROM (electrically erasable programmable read-only memory) of specific Canon Pixma printer motherboards.
: A major critique of using this tool is that it only resets the software counter. It does not physically clean the ink pads. If you reset the counter multiple times without replacing the pads, ink can eventually leak out of the bottom of the printer. Final Verdict Canon Service Tool V5610 Free Download
