Yes, a faulty paper sensor is a common cause of the E03 error, even if there's no visible paper jam. The sensor incorrectly reports a jam. Diagnosing this requires more advanced troubleshooting, often involving testing the sensor with a multimeter. Repairing or replacing the sensor is usually best left to a qualified technician.
