CHAPTER 6 SELF DIAGNOSIS

1.1 Detail Codes (copier)

E000

0000	The reading of the main thermistor does not reach 30°C 1 sec after the main
	power switch is turned on. Or, it does not reach 70°C 2 sec thereafter.
Main cause	The fixing film unit is faulty. The main thermistor has an open circuit. The
	fixing heater has an open circuit. The main power supply PCB is faulty. The
	DC controller PCB is faulty.
Caution	To reset the error, execute the following in service mode:
	COPIER>FUNCTION>CLEAR>ERR.
Action
1. Connector
	Is the connector of the fixing assembly connected?

a.main power supply PCB (J8) <-> relay connector <-> heater

b.DC controller PCB (J320) <-> relay connector <-> thermistor NO: Connect the connector.

2.Fixing film unit (thermistor)

Check the interval between pin 1 and pin 2 and between pin 3 and pin 4 of the connectosr (4-pin) of the thermistor for electrical continuity. Is it ∞Ω (open)?

YES: The heater has an open circuit, or the thermal switch is open. Re- place the fixing film unit.

4. Main power supply PCB, DC controller PCB

Press the Start key. Is the drive voltage of the heater supplied by the con- nector J8 of the main power supply PCB?

Main heater: between J8-1 (FSR1) and J8-5 (FSR COM)

Sub heater: between J8-3 (FSR2) and J8-5 (FSR COM)

YES: The heater drive power supply is faulty. Replace the main power supply PCB.

NO: The thermistor control mechanism is faulty. Replace the DC con- troller PCB.
