Canon Service Resetter Tool Info

Newer printers (2018+) use encrypted EEPROM access, making most legacy tools ineffective.

With Canon’s move to secure microcontrollers (e.g., Renesas RX family), EEPROM access is locked via cryptographic handshake. Unauthorized resetting will become impossible without hardware key extraction. This will likely shift the cat-and-mouse game to firmware patching or microcontroller replacement – both significantly harder for consumers.

Resetting the counter without replacing the felt pad leads to ink overflow into the printer’s electronics, causing short circuits, motor failure, and permanent damage.

Unlike older printers that used ribbons and impact pins, modern Canon inkjet printers work by spraying microscopic droplets of ink onto paper. To prevent the printhead from clogging, the printer performs regular cleaning cycles. During these cycles, it forces ink through the nozzles and into a spongy absorption pad inside the bottom of the printer.

This is called the Waste Ink Pad (or Absorber).

Over months and years, this pad fills up with ink. Canon engineers installed a built-in mechanical counter inside the printer's EEPROM (Electrically Erasable Programmable Read-Only Memory). The counter tracks every drop of waste ink. When the counter reaches a pre-set limit (usually around 15,000 to 20,000 pages), the printer locks itself down.

Why does Canon lock the printer?

Canon is actively fighting service resetters. Newer printers (released after 2022) feature:

Prediction: Within 3–5 years, consumer-grade Canon resetters will become obsolete for all but ancient printer models. The era of hacking ink counters is ending.

The Canon Service Resetter Tool is not universal. It works on specific chipsets. Generally, it supports:

Important: Printers newer than 2019 (TS700 series, TR8000 series, G-series MegaTank) often have encrypted EEPROMs that current resetters cannot crack. Always check specific model forums before downloading. | Feature | Official SST | Unauthorized Resetter

Using USB sniffing (e.g., Wireshark with USBPcap), researchers observed:

A typical reset command (hex dump):

40 A0 1A 00 00 00 02 00 00 00 00 00

Where 1A is start address, 02 is length (2 bytes to zero).
