000
During printing, the main thermistor detects 0°C/32°F or lower for
1 sec or more continuously.
About 10 sec or later after power-on/start of printing, the main
thermistor detects less than 120°C/248°F for 1 sec or more con-
tinuously.
After power-on/start of printing, the reading of the main thermistor
does not reach the target value -15°C/11°F or higher within 75 sec.
001
About 10 sec or later after the heater is supplied with power, the sub
thermistor detects less than 75°C/167°F for 2 sec or more continu-
ously.
Main cause
The fixing film unit is faulty (main thermistor fault, sub thermistor fault,
thermal fuse blow, fixing heater fault). The power supply PCB is faulty. The
DC controller PCB is faulty.
Action
See the descriptions for E003.
E003
During printing, the main thermistor detects less than 120°C/248°F for 1
sec or more continuously.
Main cause
