An Epson L3150 printer is a highly efficient EcoTank model, but regular use eventually triggers a mandatory maintenance alert. When the printer stops printing and flashes its red lights alternately, the internal waste ink pads have reached their operational limit.

Turn on your computer and connect the Epson L3150 directly using a high-quality USB cable. Do not attempt a reset over Wi-Fi.

Click the button. The program will read your printer's internal memory and display the current point count and percentage (which will likely be at 100%). Check the Main pad counter box once again. Click the Initialize button.
