C5300 Broken cleaning lamp wire
While the cleaning lamp is on, the bro-
ken cleaning lamp wire detection signal
is detected for 2 s continuously.
C6000 Broken fixing heater wire
• When the power is turned on or at the
start of fixing control from the sleep
mode, 10 s after fixing heater M is
turned on, the detected temperature
of fixing thermistor 2 is lower than 40
°C/104 °F.
• When the power is turned on or at the
start of fixing control from the sleep
mode, 7 s after fixing heater S is
turned on, the detected temperature
of fixing thermistor 1 is lower than 40
°C/104 °F.
• During standby, the detected
temperatures of fixing thermistors 1
and 2 become lower than 60 °C/140
°F.
C6020 Abnormally high fixing unit thermis-
tor temperature
• Fixing thermistor 1 detects
temperature 250 °C/482 °F or higher.
• Fixing thermistor 2 detects
temperature 210 °C/410 °F or higher.
C6050 Abnormally low fixing unit thermis-
tor temperature
• When only fixing heater M is on, fixing
thermistor 2 detects temperature
lower than 80 °C/176 °F during
copying.
• When fixing heater M and fixing
heater S are on, fixing thermistor 2
detects temperature lower than 80 °C/
176 °F or fixing thermistor 1 detects
