  • Printer locks printing; LEDs flashing.

Why does Epson L4166 show E11 / Service required?

The firmware monitors the waste ink usage via a software counter. Once it hits its limit, the printer blocks printing. Resetting clears that counter and restores normal function. It doesn’t always mean the ink pads are physically full.
