Canon printers do not have a universal physical "reset key", but they do use software-based adjustment programs or reset utilities for maintenance tasks such as:
✅ Types of Reset Options for Canon Printers:
- Manual Reset (Service Mode): - Some Canon printers can be reset using a special button sequence (entering Service Mode) via the printer's control panel or button presses (e.g., - Stop+- Powercombination).
 
- Used to reset the ink absorber counter, waste ink pad, etc. 
 
- Adjustment/Reset Tools (Software): - Canon uses Canon Service Tool or Canon Service Mode Tool (e.g., - Canon Service Tool v3400,- v5306, etc.).
 
- These tools allow resetting counters, cleaning heads, EEPROM adjustments, etc. 
- They are mostly intended for authorized service centers. 
 
- Canon Service Mode Utility: - This is typically a Windows-based executable. 
- Used to: 
- Example: - Canon Service Tool ST4905.exefor certain models like G series, MG series.
 
 
⚠️ Important Notes:
- Model-Specific: The tool or method depends on your specific Canon printer model. 
- Use with Caution: Incorrect use can damage firmware or void warranty. 
- Not Officially Distributed: Canon does not publicly release these tools — they are used by service technicians. 
- Ink absorber warning reset: Often the main reason for using such a tool. 
✅ Common Canon Reset Key Combinations (Service Mode Example):
For many PIXMA models (like G-series):
- Turn the printer off. 
- Press and hold the Stop button. 
- While holding Stop, press and hold Power. 
- Keep holding Power and release Stop. 
- Press Stop button 5 times (while holding Power). 
- Release all buttons — printer enters Service Mode. 
Then you can use a Canon Service Tool to reset counters or make adjustments.
