ERROR CODE
E-1
Self Diagnosis
CPU on the CLC5000’s image processor and DC controller PCB is equipped with a mecha-
nism to check the condition of the machine (sensors, in particular). The mechanism runs a check
as necessary and indicates the presence of an error upon detection.
See the tables that follow for descriptions of codes; you may check these codes using
‘JAM/ERROR’ under ‘DISPLAY’ in service mode.
‘0001’ will be used for the detailed code column of errors without a detailed code.

Cause See the descriptions that follow.
Description
“xx” represents the heater.
xx=01: upper heater
xx=02: lower heater
Cause Fixing thermistor (short circuit)
Triac (short circuit)
DC controller PCB (faulty)
Description
xx01 The overheating detection circuit on the DC controller PCB has de-
tected an overheating condition (upper heater : 230°C
lower heater : 220°C or more).
xx02 The main thermistor has detected overheating condition
(upper heater : 215°C
lower heater : 208°C or more).
Cause Fixing thermistor (poor contact, open circuit)
Fixing heater (open circuit)
Triac (faulty)
DC controller PCB (faulty)
Description
xx05 A difference of 60°C or higher is detected between the reading of
the main thermistor and that of the sub thermistor.
xx20 When control is to 160°C or less, a rise in temperature of 10°C or
more does not occur within 4 min.
xx40 The temperature drops to 140°C or less during temperature control
for standby.
xx50 The temperature drops to 140°C or less during temperature control
for printing.
