Error code Detail code Symptom Description
E000 0000 The fixing temperature fails
to increase. In the course of start-up control, the thermistor reading
is less than 30 deg C 1 sec after the start of power supply
or is less than 70 deg C 2 sec after the start of power
supply; the machine will identify an error condition if
any of the foregoing continues for 200 msec or more.
E001 0000 The thermistor detects
overheating. The thermistor detects 235 deg C for 200 msec or more
continuously.
0001 A hardware circuit detects
overheating. A hardware circuit detects overheating in relation to the
thermistor (main or sub).
0002 The sub thermistor detects
overheating. The thermistor detects 295 deg C or more for 200 msec
or more continuously.
E002 0000 The fixing temperature fails
to reach a specific level. In the course of start-up control, the thermistor detects a
temperature lower then 115 deg C for 200 msec
continuously after it has detected 100 deg C; the
thermistor detects a temperature less than 150 deg C for
200 msec or more continuously after it has detected 140
deg C; or, the thermistor detects a temperature lower
than 165 deg C for 20 msec or more continuously 1 sec
after it has detected 160 deg C.
E003 0000 The fixing temperature has
dropped to an abnormally
low level. In the course of normal temperature control, the
thermistor detects a temperature lower than 140 deg C
for 20 msec or more continuously.
E007 0000 The fixing film rotates in an
abnormal way. The reading of the main thermistor is in excess of 100
deg C with the fixing motor in a locked state and, in
addition, the machine fails to detect the marker signal
for 6 sec.
E014 0000 The machine detects a
fixing motor error. During operation, the machine detects an overload
condition continuously for 3 sec or more.
