Solutions

Diagnóstico rápido

If the lights blink in an E3 pattern, check if paper is physically stuck or if the sensor path is dirty. Do not force the paper out, as you may damage the internal sensor flag.

Solución paso a paso

  1. Power Down: Turn off the printer and let it cool for 10 minutes.
  2. Remove Drum: Take out the toner and drum unit to inspect the paper path.
  3. Clear Jam: Pull any jammed paper gently using both hands.
  4. Clean Sensors: Blow out any loose toner or dust around the sensor flags.

Prevención y mantenimiento

Ensure paper is correctly aligned in the tray. Use only quality paper within the weight spec. Consistent use of original DR-1060 drum units reduces the likelihood of sensor-based error codes.

Cuándo llamar a un técnico

If the E3 error persists after cleaning and rebooting, the paper sensor unit might be disconnected or physically broken.

Frequently asked questions

The E3 code indicates a paper jam or that the paper sensor is blocked by debris or spilled toner.

After clearing the jam, opening and closing the front cover signals to the printer that the path is clear.

Use original TN-1060 toner and DR-1060 drum units to ensure consistent performance.

A light cleaning once every few months with a dry cloth helps prevent false jam alerts.
