Control panel message Status alert Description Recommended action
50.10 Fuser error
Fuser is defective (abnormal
high temperature of the
thermistor)
1. Reconnect the connectors
of the fuser unit (J802) and
DC controller PCA (J104).
2. Measure the resistance
between the connector
J802-1 and J802-3 on the
fuser. If the resistance is
not within the range from
approximately 220 kΩ to
660 kΩ (at ambient
temperatures), replace the
fuser.
3. Replace the fuser power
supply unit.
50.12 Fuser error
Fuser is defective (Fuser 1
pressure release mechanism
failure)
1. Reconnect the connectors
of the DC controller PCA
(J110, J115).
2. Check the sensor flag of
the fuser pressure release
sensor. If the sensor flag is
damaged, replace it.
3. Replace the fuser motor.
4. Replace the high-voltage
power supply unit.
5. Replace the fuser unit.
50.2 Fuser error
Fuser is defective (warm-up
failure)
1. Reconnect the connectors
of the fuser unit (J802) and
DC controller PCA (J104).
2. Measure the resistance
between the connector
J801-1 and J801-3 on the
fusier. If the resistance is
not within the range from
approximately 220 kΩ to
660 kΩ (at ambient
temperatures), replace the
fuser.
3. Reconnect the connectors
of the fuser power supply
unit (J201, J202, J203).
4. Measure the resistance
between the connector
J801-1 and J801-2 on the
fuser. If the resistance is
not within the range from
approximately 21 Ω to 25 Ω
(at ambient temperatures),
replace the fuser.
5. If the message persists,
replace the fuser power
supply unit.
