CHAPTER 6 SELF DIAGNOSIS

6-4 T

E001

0000 The main thermistor detects 250°C or higher.
0001 The main thermistor or the sub thermistor detects overheating (hardware
circuit detection).
0002 The sub thermistor detects about 295°C or higher.
Main cause The fixing film unit is faulty (i.e., the thermistor has a short circuit). The
main power supply PCB is faulty. The DC controller PCB is faulty.
Caution To clear the error, execute the following in service move:
COPIER>FUNCTION>CLEAR>ERR.
Action
1. Fixing film unit
Check the interval between pin 1 and pin 2 and between pin 3 and pin 4 of
the connectors (4-pin) of the thermistor for electrical continuity. Is it 0

(short circuit)?
YES: The thermistor has a short circuit. Replace the fixing film unit.

REF.

If the thermistor has a short circuit, the indication in service mode
(COPIER>DISPLAY>ANALOG) will be as follows from the start: FIXC=
250°C for the main thermistor; FIX-E=310°C for the sub thermistor.
2. Main power supply PCB, DC controller PCB
Try replacing the main power supply PCB. Is the problem corrected?
YES: End.
