Failure Detection
The CPU performs error detection at intervals of 40 msec. If any one of the cases a to d occurs, the CPU stops the machine completely. To restart the machine,
remove the cause of the failure and carry out initial rotation. If a failure is detected, an error code "EXXX" is displayed on the operation panel.
MEMO:
In case of this machine, the detail code of the error code of this machine can be confirmed in the following service mode.
Service mode > ERROR DISPLAY
a. Failure at startup
1) The main thermistor has detected temperatures lower than 30 deg C continuously for 400 or more msec since 1 second lapsed after energization of the fixing
heater.
2) The main thermistor has detected temperatures lower than 70 deg C continuously for 400 or more msec since 2 seconds lapsed after energization of the fixing
heater.
3) The sub-thermistor has detected temperatures lower than 75 deg C continuously for 400 or more msec since 5 seconds lapsed after energization of the fixing
heater.
4) The temperature rise detected by the main thermistor is less than 5 deg C when energization of the fixing heater starts, when the temperature detected by the
main thermistor is less than 100 deg C, or when 1 sec has lapsed since start of energization.
5) The main thermistor has detected temperatures less than 115 deg C continuously for 400 or more msec since 1 second has lapsed after detection of 100 deg C.
6) The main thermistor has detected temperatures less than 150 deg C continuously for 400 or more msec since 1 second has lapsed after detection of 140 deg C.
7) The main thermistor has detected temperatures less than 165 deg C continuously for 400 or more msec since 1 second has lapsed after detection of 160 deg C.
8) The target printing temperature is not reached when 30 seconds have lapsed since start of the initial rotation.
b. Low temperature detection during temperature control
During temperature control, the main or sub thermistor has detected low temperatures continuously for 400 or more msec after the target temperature was reached.
c. Abnormally high temperature detection
1) The main thermistor has detected 240 C deg irrespective of whether the fixing heater is of or off.
2) The sub thermistor has detected 295 deg C irrespective of whether the fixing heater is of or off.
d. Drive circuit failure
1) The zero crossing signal frequency of the power supply has not been detected during initial rotation.
2) During temperature control, no zero crossing signal has been input for 3 seconds.
3) A triac short circuit has been detected in the ASIC.
4) An abnormally high temperature has been detected in the ASIC.
5) A lock condition has been detected in the fixing motor.
Fixing System Error Codes
E000-0000 STARTUP ERROR
The temperature detected by the main and sub thermistors did not reach the prescribed temperature during startup control.
E001-0000 ABNORMALLY HIGH TEMPERATURE (detected by main thermistor)
The main thermistor detected an abnormally high temperature (250 deg C) during temperature control.
E001-0001 ABNORMALLY HIGH TEMPERATURE (detected by sub thermistor)
The sub thermistor detected an abnormally high temperature (295 deg C) during temperature control.
E002-0000 LOW TEMPERATURE DETECTED DURING TEMPERATURE CONTROL
The main and sub thermistors detected an abnormally low temperature (140 deg C) during temperature control.
E003-0000 ABNORMALLY LOW TEMPERATURE (detected by main thermistor)
The temperature detected by the main thermistor does not reach the target temperature during initial rotation after it has reached the target temperature.
E003-0001 ABNORMALLY LOW TEMPERATURE (detected by sub thermistor)
The temperature detected by the sub thermistor does not reach the target temperature during initial rotation after it has reached the target temperature.
E007-0000 ABNORMALLY ROTATION of FIXING FILM (detected by fixing film speed sensor)
A fixing film rotation failure has been setected.
E808-0000 DRIVE CIRCUIT FAILURE
A zero crossing signal cannot be detected.
A fixing drive motor failure has been detected.
