If your printer is working, block automatic firmware updates. New EPSON firmware (version after 2022) actively blocks third-party adjustment tools. If you are on new firmware, only WIC Reset Utility (paid) will work.
Assuming you have downloaded a functioning Adjustment Program (Service Tool).

The EPSON Adjustment Program Reset L380-L383-L385-L485 is a specialized tool designed for technicians and advanced users to reset and adjust the internal counters of EPSON printers, specifically the L380, L383, L385, and L485 models. These printers, part of EPSON's popular line of inkjet printers, are known for their reliability and high-quality printing. However, like any printer, they can encounter issues that require professional-level intervention, such as problems with ink pad counters or waste ink counters.
Extract the downloaded ZIP file. Do not run it from the ZIP. Move the folder to your Desktop. Right-click the .exe file and select "Run as Administrator." If your printer is working, block automatic firmware
Click "Check" once more. The counter should now read 0.0% (or 0 percent). Congratulations, the software lock is gone.
The Adjustment Program (also called the "Reset Utility" or "Service Tool") is a Windows-based executable (e.g., AdjProg.exe). It communicates directly with the printer’s EEPROM via USB. Key functions include: Note: This paper is for educational and technical
| Function | Purpose | |----------|---------| | Waste Ink Pad Counter Reset | Resets the counter to zero. | | Initial Ink Charge | Performs initial ink filling (for new printheads or after ink system replacement). | | Head ID Input | Writes printhead calibration data. | | Ink Freeze / Thaw | Temporarily disables ink monitoring (for troubleshooting). | | EEPROM Backup/Restore | Saves/loads printer’s serial number and configuration. |
For the L380–L485 series, the critical function is the Protection Counter Reset (waste ink counter).
Using the EPSON Adjustment Program voids your manufacturer's warranty. However, if your printer is already out of warranty (most L380-L485 models are several years old), this is irrelevant. Epson designs these counters to force you to visit a service center. Technicians charge $50-$80 for this 2-minute reset. Using the program yourself is effectively "right to repair."
