What Is the Resetter Adjustment Program?

The Resetter Adjustment Program (commonly referred to as a “WIC resetter” or “adjustment program”) is a software utility designed for service technicians. Its primary function is to communicate with the printer’s EEPROM (electrically erasable programmable read-only memory) to reset the waste ink counter. For the Epson L4150, L4160, and L4170 models, this program is model-specific and typically runs on Windows-based computers. It bypasses the printer’s user-level warnings and performs a low-level reset, restoring normal operation.
