CHAPTER 6 SELF DIAGNOSIS
6-1 T
1. Error Codes
1.1 List of Error Codes
The machine is equipped with a mechanism to run self diagnosis to find out its condition
(particularly of its sensors): CPU on the main controller PCB and the CPU on the DC con-
troller PCB. If it finds a fault, it indicates the nature of the fault in its control panel.
The following is a list of codes and descriptions (including timing of detection); a code
may have detailed codes, which may be checked in service mode (COPIER>
DISPLAY>JAM/ERR).
E000
Main Cause The main thermistor (TH1) has poor contact or an open circuit. The thermal
switch (TP1) has an open circuit. The fixing heater has an open circuit. The
SSR is faulty. The DC controller PCB is faulty.
Mode of
Detection
0000 After the main power switch is turned on, the temperature detected
by the main thermistor does not reach 70°C.
Caution The error must be reset in service mode (COPIER>FUNCTION>
CLEAR>ERR).
E001
Main Cause The main thermistor (TH1) has a short circuit. The sub thermistor (TH2)
has detected overheating. The SSR is faulty. The DC controller PCB is
faulty.
Mode of
Detection
0001 The main thermistor or the sub thermistor has detected about
230°C or higher for 2 sec.
0002 The main thermistor has detected 230°C or higher (hard circuit de-
tection).
0003 The sub thermistor has detected about 236°C or higher.
Caution The error must be reset in service mode (COPIER>FUNCTION>
CLEAR>ERR).
