- 3Contaminated printhead requiring extra power.
- 4High ambient environmental temperature.
Solutions
Quick Diagnosis
If you have been printing large volumes, the thermal elements have reached their design limits for heat dissipation.Step-by-step Solution
- Shut down the printer immediately.
- Open the printer cover to expose the head.
- Wipe the head clean with an alcohol pen to remove debris.
- Wait 15-20 minutes before resuming operation.
Prevention and Maintenance
Lower the 'Darkness' or 'Heat' settings in your driver if a perfect black print isn't mandatory. Use high-quality consumables.When to call a technician
If the error appears instantly upon cold startup without printing, the temperature sensor is malfunctioning.Equipment Technical Data
