Solutions

Quick Diagnosis

If the display shows E002 shortly after startup, the system failed its initial fuser temperature check. This is a hardware-level thermal issue, not a paper jam.

Step-by-step Solution

  1. Power off the printer and unplug it.
  2. Wait 30 minutes to ensure the fuser unit is completely cool.
  3. Plug directly into a stable wall outlet, bypassing surge protectors.
  4. Power on the unit and allow it to complete the warmup phase.

Prevention and Maintenance

Avoid running extremely high-volume print jobs without pauses. Using genuine 067 series toner prevents buildup that can overload the fuser unit.
