Resetting the digital counter does not magically clean the physical ink pads. If you reset the printer multiple times without replacing or washing the internal foam pads, excess ink will eventually leak out and damage your desk or the printer's internal electronics.
Press and (usually a red triangle inside a circle).
To verify the reset, go to the section at the top of the tab and click EEPROM . The printer will feed a sheet of paper and print out a log page. Check the line that says D= or BK= ; it should now read 000.0 , indicating a successful reset. Step 4: Exiting Service Mode Close the Service Tool software application.
If you plan to use this tool frequently, consider installing an external waste ink bottle modification to safely route excess ink outside the printer chassis.
(e.g., TS series, TR series, G-series MegaTank). Those require newer service tools like V5400 or V5500, and using an old version may corrupt the EEPROM.
Close the application, turn off the printer, wait 10 seconds, and turn it back on. Your printer should now function normally. Important Safety Warning and Troubleshooting
This means the software cannot establish communication with the printer chip.
Unlike older versions of the software, version V5204 features updated compatibility for newer printer mainboards. It communicates directly with the printer’s firmware via a USB connection, bypassing standard consumer drivers to alter system values. Supported Canon Printer Models
This means the software cannot communicate with the printer firmware. The most common cause is that the printer is not in Service Mode , or you are using an incorrect USB port. Ensure the printer's green light is solid before launching the app.
Companies like and InkOwl sell hardware resetters ($15–$30) that plug into the printer’s rear service port. These are certified, virus-free, and work without entering service mode manually.
Often works with printers using PGI-550/CLI-551 through PGI-580/CLI-581 cartridge generations.
