"Analysis of Service Utility Tools for Epson EcoTank Printers: Case Study of the L6490 Adjustment Program"
We obtained a copy of the "Epson L6490 Adjustment Program.exe" (MD5: 6a4f2b...). The tool was executed in an isolated Windows 7 VM with USB monitoring (USBPcap) and API call tracing (API Monitor). The printer was connected via USB; a logic analyzer tapped the communication lines between the printer’s mainboard and the waste ink EEPROM (24LC256).
Click the "Particular adjustment mode" or "Initial setting" button. The program will prompt you to enter a destination ID (usually 10001 for North America or EU01 for Europe—check your printer’s manual region).
