The Canon Service Tool v3900 is a specialized software utility designed for service-level maintenance of Canon printers. Unlike standard printer drivers or the official Canon IJ Printer Assistant Tool, this program grants low-level access to the printer's EEPROM memory and internal counters. It is primarily used for tasks like resetting the waste ink counter, running service test prints, and performing EEPROM operations, and is typically intended for authorized Canon service centers.
To prevent ink from leaking out of the machine, Canon programs an internal counter. Once this counter hits a specific limit (usually 100%), the printer locks itself down. The V3900 software communicates directly with the printer’s firmware via a USB connection to reset this counter back to 0%. Key Features of V3900
