6.6.7 Detecting Low Temperature of Oil (software)
The CPU on the DC controller PCB monitors the voltage of the oil thermistor (TH5) and
the oil heater thermistor (TH6), and the DC control PCB will issue the following error codes
in the presence of a fault and then cause the power OFF signal (PWOFF*) to go ‘0’, thereby
turning off the power switch (SW2):
Thermistor Condition Error code
Oil thermistor (TH5) It does not reach 50ºC after the end E000-0062
of WAIT.
Oil heater thermistor (TH6) It does not reach 50ºC after the end E000-0072
of WAIT.
6.6.8 Detecting Low Temperature of Oil (hardware)
If the low temperature detention circuit on the DC controller PCB doesn’t detect 50ºC
within 2 min after the oil heater turns on the following error code will be issued:
Thermistor Error code
Oil heater thermistor (TH6) E000-0082
6.6.9 Operation of the Thermal Switch
If the temperature inside the thermal switch of the upper fixing heater, lower fixing heater,
or oil heater exceeds 230ºC, the respective switch turns off to cut off the power to its heater.
REF.
The contact of the thermal switch (TP1, TP2, TP3) will not recover even
when the temperature returns to normal. Do not use it once its contact has
opened.
Resetting E000
1) Remove the cause.
2) Start service mode, and make the following selections:
FUNCTION>USER.
3) Press ‘E000-RLS’ so that the <P> notation will change as follows: ER-
ROR → BUSY → ERROR.
4) Turn off and then on the power switch.
