Epson EcoTank ET-M1170 error E-12: Solution

The Epson EcoTank ET-M1170 error E-12 indicates that the paper feeder sensor is not detecting the presence of sheets, even though the tray is loaded. This frequently occurs if there are paper residues blocking the optical sensor or if the rollers are too slippery. To fix the E-12 error on the Epson EcoTank ET-M1170, it is necessary to clean the loading area internally. This device is highly reliable, but dust can interfere with its precision sensors.

Common causes

  • 1Dust accumulated on the optical sensor lens.
  • 2Small paper scraps jammed under the tray.
  • 3Worn rubber rollers that do not move paper to the sensor.
  • 4Paper sensor out of its original position.

Solutions

Diagnostic

If you notice the feed motor running but the printer stopping immediately, the sensor is failing to register the paper path (E-12).

Step-by-Step Solution

  1. Remove all paper from the front tray.
  2. Visually verify that no paper remnants exist at the base of the printer.
  3. Use compressed air (cautiously) to clean the paper sensor area near the rollers.
  4. Adjust the paper guides so they slide smoothly without pressing too hard.

Prevention and Maintenance

Do not use damp paper or paper stored in high humidity. Clean rollers with isopropyl alcohol if they seem to slip.

When to call a technician

If after cleaning the roller area and the sensor the machine still reports E-12, the sensor might be electrically damaged and require replacement.
