The Epson L14150 Resetter is a piece of software designed to interface directly with the printer’s firmware. Its primary function is to reset the "protection counter," effectively telling the printer that the waste ink pads are new, thereby bypassing the lockout. However, calling it a "resetter" simplifies its capabilities. The Adjustment Program is a diagnostic suite, offering access to the printer's EEPROM (Electrically Erasable Programmable Read-Only Memory). It allows for ink charging, head cleaning, and paper feed adjustments—functions essential for maintenance but locked away from the standard user interface.
The Epson L14150 Adjustment Program resets the "Service Required" error by clearing the internal waste ink pad counters via a USB connection. Users must temporarily disable antivirus software, run AdjProg.exe on Windows, select the L14150 model, and initialize the main/platen pad counters to zero. Watch a video tutorial at YouTube .
