In a heater-off state, the
detection temperature of fuser
thermistor 1 is higher than
195°C/383°F after the detec-
tion temperature of fuser
thermistor 1 was 155°C/311°F
or less.
(40 ppm model)
The detection temperature of
fuser thermistor 1 is higher
than 250°C/482°F.
In a heater-off state, the
detection temperature of fuser
thermistor 1 is higher than
170°C/338°F after the detec-
tion temperature of fuser
thermistor 1 was 155°C/311°F
or less.

6130 Broken fuser thermistor 1
wire
(50/60 ppm model only)
A/D value of the fuser thermis-
tor 1 exceeds 1019 bit contin-
uously for 4 s during warming
up.
Connector cable or
poor contact in the
connector
Reinsert the connector. Also check for conti-
nuity within the connector cable. If none,
replace the cable.
