Code
E001
Fixing high temperature error
0000 Condition
The reading of the main thermistor is 260 deg C or more.
Cause
The main thermistor is faulty. The DC PCB is faulty.
0001 Condition
The reading of the sub thermistor is 290 deg C or more.
Cause
The sub main thermistor is faulty. The DC PCB is faulty.
0002 Condition
The safety circuit (of the DC controller) has detected a high temperature error
(about 260 deg C or more).
Cause
The thermal switch is faulty. The low-temperature power supply PCB is
faulty. The DC PCB is faulty.
E003
Fixing low temperature error
0000 Condition
In 20 sec after the fixing heater has gone on, the reading of the main thermistor
is 120 deg C or less.
Cause
The main thermistor is faulty. The DC controller is faulty. The connector has
poor contact, or the harness is faulty.
0001 Condition
In the course of printing temperature control, the reading of the sub thermistor
is 80 deg C or less for 2 sec or more.
Cause
The sub thermistor is faulty. The DC controller PCB is faulty. The connector
has poor contact, or the harness is faulty.
0002 Condition
During initial rotation, the reading of the main thermistor is 50 deg C or less
0.2 sec after the start of temperature control.
Cause
The DC controller PCB is faulty. The connector has poor contact, or the
harness is faulty.
E004 Thermistor is not connected
0000 During walm-up rotation, the thermistor connection signal (FUSER CNCTX)
is open.
E009 Error in pressure/release of fixing film unit
0001 In case that the output of fixing automatic pressure phase sensor is not changed
although rotating/reversing the fixing motor
E808 Low-voltage power supply circuit fault (zero-cross error)
0000 The low-voltage power supply circuit fault (zero-cross error)
Cause
The low-voltage power supply PCB is faulty. The DC controller PCB is faulty.
E840 Fan shutter error
0000 Fan shutter open/close operation Error
Cause
Abnormal rotation of the fan shutter motor
Defect of the fan shutter position sensor
Defect of the fan shutter home position error
Defect of the DC controller PCB
