Common causes

  • 1Paper debris stuck in the sensor slot.
  • 2Dust accumulation affecting the optical sensor.
  • 3Mechanical misalignment of the feed roller.
  • 4Electronic board fault in the sensor module.

Solutions

Quick Diagnosis

If this error persists, examine the input path with a flashlight. Small scraps of paper or curled edges are the most frequent culprits triggering the sensor fault.

Step-by-Step Solution

  1. Unload all paper media.
  2. Inspect the loading slot for obstructions.
  3. Carefully remove debris with tweezers.
  4. Clean the sensor lens with low-pressure air.
  5. Restart the machine and reload the media.

Prevention and Maintenance

Avoid using creased or damaged media, as this often confuses the detection sensors. Keep the feed area clear of paper dust buildup to ensure sensor accuracy. Use genuine Epson rolls to guarantee perfect alignment.

When to Call a Technician

If the fault persists even after cleaning and removing all debris, the sensor assembly may be faulty and requires a technical replacement.
