  • Gaps in the nozzle check after refilling

    moderate

    If your nozzle check still prints with gaps after you refill empty tanks, Epson says the ink tubes may need filling and to run a Power Cleaning, with each tank at least one-third full and at least 12 hours between cleanings. If quality doesn't improve after several, contact Epson.

  • Waste ink pads reach end of life

    moderate

    The ink pads inside the printer soak up ink that doesn't end up on the page, and they can reach the end of their usable life. The screen shows W-11 when a pad is nearing the end and E-11 when it needs replacing. You can't replace them yourself: Epson covers it under the standard warranty, and out of warranty you contact Epson.
