Common causes

  • 1Temperature sensor (thermistor) failure.
  • 2Exhausted fuser heat lamp.
  • 3Internal paper jam blocking heat transfer.
  • 4Toner residue buildup causing thermal short circuit.

Solutions

Quick Diagnosis

If the error appears as soon as you turn the machine on, the thermal sensor (thermistor) is failing. If it appears after attempting to print, the fuser might be taking too long to heat due to lamp wear.

Step-by-Step Solution

  1. Forced Cool Down: Let the machine rest while turned off for at least 20 minutes.
  2. Output Inspection: Look through the rear tray for paper remnants blocking the fuser output.
  3. Restart Test: Turn on the machine; if the error persists, the fuser unit needs professional service.

Maintenance and Prevention

Avoid turning the machine on and off constantly as this stresses the thermistor. Keep the rear ventilation area clear for proper heat dissipation.

When to Call a Technician

The fuser is a high-voltage electrical part. If the E30 is persistent, call a professional technician; do not attempt to manipulate the internal unit.
