ERROR CODE
E-1
1 Self Diagnosis (copier)
The R-CPU and DC-CPU of the machine’s CPU PCB are equipped with a mechanism to
check the machine’s state (particularly, sensors). It runs a check as needed and, upon detec-
tion of a fault, indicates a code on the control panel.
What follows below are lists of error codes and descriptions of faults and conditions of
detection; the detail codes indicated under each error code are indicated in service mode:
COPIER>DISPLAY>JAM>ERR.
E000
Main cause The fixing heater is faulty. The SSR is faulty. The fixing thermistor is
faulty. The DC controller PCB is faulty. The system controller PCB is
faulty.
Condition of
detection
xx=01: Main thermistor (TH1), xx=02: Sub thermistor (TH2)
xx01 The thermistor (TH1, TH2) has detected 245°C or higher (hard-
ware detection).
0002 The thermistor (TH1) has detected 240°C or higher (software de-
tection).
Main cause The fixing heater is faulty. The SSR is faulty. The fixing thermistor is
faulty. The thermistor (TH1, TH2) has an open circuit. The thermal switch
(TP1) has turned on.
Condition of
detection
xx=01: Main thermistor (TH1), xx=02: Sub thermistor (TH2)
xx03 The thermistor (TH1, TH2) has detected an open circuit.
0021 Within a temperature range of 50°C or lower as detected by the
thermistor (TH1), the increase in temperature in 1 min is less than
3°C.
0031 Within a temperature range between 50°C and 190°C as detected
by the thermistor, the increase in temperature within 30 sec is less
than 5°C.
0040 During standby, the fixing temperature has dropped below 140°C.
0050 During printing, the fixing temperature has dropped below 140°C.
E004
Main cause The SSR1 is faulty.
Condition of
detection
xx=01: Main heater (H1), xx=02: Sub heater (H2)
xx01 SSR1 for the fixing heater is ON even though the fixing heater
(H1, H2) is OFF.
