If you reset the counter without replacing or cleaning the physical waste pads, the excess ink will eventually overflow out of the bottom of the printer, ruining your desk, carpet, or internal printer electronics. After resetting the software, consider opening the lower maintenance panel of the printer to wash out the felt pads and let them dry, or install an external waste ink bottle mod to catch future discharge safely. To proceed with your printer maintenance, let me know:

The Service Tool only runs natively on Windows operating systems (Windows 7, 8, 10, or 11). It does not work on macOS.
The printer does not have a physical sensor to check if the pads are wet. Instead, an internal microchip (EEPROM) calculates ink accumulation mathematically.
Before you begin, understand that using this tool improperly can void your warranty (if any remains) or brick your printer. Proceed at your own risk.
