My Epson L3110 isn't detecting ink or showing incorrect ink levels. What's the solution?

Ensure all ink tank caps are properly sealed and that the ink tanks are filled to the appropriate levels with genuine Epson ink. Check that the printer's internal ink system (tubes) appears to have ink flow. If the printer still reports incorrect levels, try turning the printer off and on. If the issue persists after confirming ink levels, it might be a sensor issue, which could require professional service.
