1. Details of Errors Associated with the Fixing System

If a fault occurs in the fixing assembly, the machine indicates an appropriate error code and disables printing operation. In most cases, you will have to replace the fixing film or the fixing assembly to reset the machine.

　

Error code Detail code Error Description E000 0000 The fixing temperature fails to increase. During start-up control, any of the following conditions is detected continuously for 200 msec or more: 1)the reading of the main thermistor is less than 30 deg C 1 sec after the start of power supply. 2)the reading of the main thermistor is less than 70 deg C 2 sec after the start of power supply. E001 　 0000 Overheating is detected in the main thermistor. The reading of the main thermistor is 235 deg C continuously for 200 msec. 0001 Overheating is detected by the hardware circuit. The hardware circuit detects overheating in the main thermistor or the sub thermistor. 0002 Overheating is detected in the sub thermistor. The reading of the sub thermistor is 295 deg C continuously for 200 msec or more. E002 0000 The fixing temperature fails to reach a specific value within a specific period of time (temperature rise fault). At time of startup control, any of the following conditions is detected for 200 msec continuously: 1)the reading of the main thermistor detects 100 deg C and then is less than 200 msec 1 sec thereafter. 2)the reading of the main thermistor is 140 deg C and then less than 150 deg C 1 sec thereafter. 3)the reading of the main thermistor is 160 deg C and then is less than 165 deg C 1 sec thereafter E003 0000 The fixing temperature has dropped abnormally (low error temperature). At time of normal temperature control, the reading of the main thermistor is less than 140 deg C continuously for 200 msec. E007 0000 The rotation of the fixing film is not detected. While the fixing motor is being driven and the reading of the main thermistor is in excess of 100 deg C, the marker signal is not detected or 6 sec.

　

Caution

You will not be able to reset an error code by merely turning off and then on the machine. Be sure to use service mode. (For instructions, see the descriptions of the tasks of the service person.)
