9.4 Protective Functions
9.4.1 Detecting an Error Using the Thermistor
0015-4618
iR5065 / iR 5055 / iR5075 / iR5075N / iR5065N / iR5055N
In the event of the following, the machine will set the DC power (+12 V) used to drive the AC relay (found on the fixing heater power supply PCB), thereby stopping
the AC power to the fixing heater.
- the main thermistor (TH1)/sub thermistor (TH2)/shutter thermistor (TH3) has detected overheating.
- the difference between readings of the main thermistor and the sub thermistor or between the main thermistor and the shutter thermistor has deviated from a specific
value.
9.4.2 Detecting an Error Using the Thermal Switch
0015-4620
iR5065 / iR 5055 / iR5075 / iR5075N / iR5065N / iR5055N
In response to a deviation in temperature (200 +/-5 deg C), bimetal contact of the thermal switch (TP1; non-contact type) will open to cut the power supply line
(+12 VDC) used to drive the AC relay on the fixing heater power supply PCB, thereby stopping the AC power to the fixing heater.
Once open, the contact of the thermal switch will not reset itself even when the temperature drops to normal; be sure to replace the thermal switch after removing
the error.
9.4.3 Errors
0015-4621
iR5065 / iR 5055 / iR5075 / iR5075N / iR5065N / iR5055N
ERROR CODE:
E000 (low temperature detection error)
0000 after power-on, the reading of the main thermistor is not 70 deg C or higher within 20 sec .
0010 the power has been turned off and then on without resetting the error in question.
E001 (abnormal rise in temperature)
0001 the main thermistor or the sub thermistor has been identified as being faulty, or an open circuit has been detected.
0002 the reading of the main thermistor or that of the sub thermistor is 230 deg C or higher for 2 sec.
0003 the reading is not 150 deg C or higher or 210 deg C or lower within 30 sec (at time of a remedial job).
0010 the power has been turned off and then on without resetting of the error in question.
E002 (faulty rise in temperature)
0000 the reading of the main thermistor is in excess of 70 deg C and, thereafter, it does not reach 150 deg C within 12 sec.
0001 the reading of the main thermistor is in excess of 100 deg C and, thereafter, it does not reach 150 deg C within 15 sec.
0010 the power has been turned off and then on without resetting of the error in question.
E003 (faulty rise in temperature)
0000 the reading of the main thermistor is in excess of 100 deg C and, thereafter, is lower than 70 deg C for 2 sec or more.
