C6020: Thermopile high temperature error
1. The thermopile detected 200°C/392°F or more for 5s.
2. The thermopile detected 200°C/392°F or more for 0.5s when passing 1s or more after the drive stopped.
(however, at the emergency stop, the relay circuit is used and this detection is not done.)
C6030: Broken thermopile
The thermopile AD value is abnormal.
C6050: Thermopile low temperature error
During stand-by or printing, the thermopile detected less than 100°C/212°F for 3s consecutively.
Step Check description Assumed cause Measures Reference
1 Checking the connection The connector is not prop-
erly connected or the wire

Step Check description Assumed cause Measures Reference
1 Changing the external
power source
The power supply voltage
reduces.
Connect the power cord to a
different wall outlet if the
power supply voltage
descends by 10% or more of
the rated voltage, or multiple
devices use the same outlet.
