Quick Diagnosis

If you see the E-02 code, inspect the main paper tray and the rear feed path. Often, a tiny scrap of torn paper can trigger this sensor error.

Step-by-step Solution

  1. Open Scanner: Lift the scanner unit to reveal the internal printing area.
  2. Check for Paper: Look for any stuck paper or debris inside the mechanism using a flashlight.
  3. Extract Carefully: Gently pull the paper out with both hands to ensure no fragments remain in the rollers.
  4. Reset: Close the scanner cover and press the OK or Start button to clear the alert.

Prevention and Maintenance

Use only high-quality printer paper. Avoid damp sheets or paper with curled edges. Clean the feed rollers with a soft, lint-free cloth dampened with water every 3 months. Always use genuine Epson 502 ink to prevent clogging issues that might stall paper movement.

When to Call a Technician

If the error persists after all paper fragments have been cleared, the internal paper sensor may be broken and requires professional service.
