KX-MB2230JT/ KX-MB2270JT/ KX-MB2515JT/ KX-MB2545JT/ KX-MB2575JT/ DP-MB310JT
The fuser and developer
start working.
The temperature
control starts working.
Detection 6
Checks the temperature of 235℃ or above.
(The detection takes place every 10 msec.)
Detection 7
Checks the short of the thermistor (AD: 0).
(The detection takes place every 10 msec.)
Detection 8
When the unit can not be controlled by
the software, it should be stopped forcibly
by the hardware(ASIC). (250℃)
Detection 9
Thermostat temperature reached 160℃.
Paper is picked up.
Detectionj
When the unit can not be controlled by
the software,it should be stopped forcibly
by the hardware(comparator).(240℃)
The usual fixing temperature is 195℃.
But in case of "Half speed mode" (exclude special paper :
Thick paper / Envelope / Card stock etc...), the fixing temperature
may down to 170℃.
When one of the followings happened, processing glitches are executed and unit goes
to "CALL SERVICE 3".
[Low temperature detection]
Detection 1: The AD value of the temperature does not go up 4 or more in 10 sec.
after the heater is turned ON.
Detection 2: The temperature does not reach primary stable temperature (170℃)
within 50sec after the heater is turned ON.
Detection 3: The temperature does not reach the secondary stable temperature
(170℃/195℃) within 75sec from primary stable temperature (170℃).
Detection 4: The temperature decreased 60deg (110℃/135℃) or more by the temperature
control after reaching the secondary stable temperature (170℃/195℃).
Detection 5: The temperature does not reach the primary stable temperature (170℃)
within 30sec from detection temperature 1 (70℃).
[High temperature detection]
Detection 6: During printing the temperature became 235℃ or above.
Detection 7: During printing the short of the thermistor (AD: 0) was detected.
Detection 8: When the unit can not be controlled by the software, it should be stopped
forcibly by the hardware (250℃).
Detection 9: The thermostat temperature reached 160℃.
Detection j: When the unit can not be controlled by the software,it should be stopped
forcibly by the hardware(comparator).(240℃)
