Description: Sensor Failure: #A3-3111. Turn off then on. Call for service if the problem persists Sensor Failure: #A3-3112. Turn off then on. Call for service if the problem persists
Causes: The NC sensor in the fuser unit is defective. / The sensor signal is abnormal due to a defective harness. • A3–3111 : Center NC sensor is in short status. • A3–3112 : Center NC sensor is in open status. • A3–3113 : Side NC sensor is in short status. • A3–3114 : Side NC sensor is in open status.
Remedy: 1) Remove and disassemble the fuser unit. 2) Measure the resistance value of the thermistor (1404-001453). If the measured value is out of 307KΩ~430KΩ @25℃, replace the thermistor. 3) Install the fuser unit after replacing the thermistor. 4) If the error persists, replace the fuser unit (JC91-01163A(220V) / JC91–01164A (110V)). 5) If the error persists after replacing fuser unit, replace the main board(JC92–02746A).

Description: Sensor Failure: #A3-3210. Turn off then on. Call for service if the problem persists Sensor Failure: #A3-3211. Turn off then on. Call for service if the problem persists Sensor Failure: #A3-3212. Turn off then on. Call for service if the problem persists
Causes: Inner temperature sensor is defective. • A3–3210 : Inner temperature sensor value is abnormal. • A3–3211 : Inner temperature sensor is in short status. • A3–3212 : Inner temperature sensor is in open status.
Remedy: 1) Open the side cover. Check the inner temperature sensor connection. • If the connection is OK, replace the photo sensor (1404-001417). 2) If the sensor is normal, replace the main board(JC92-02746A).
Code: A3-3310, A3-3311, A3-3312

Causes: Symptom Outer temperature/humidity sensor is defective. • A3–3310 / A3–3311 / A3–3312 : Temperature function is abnormal. • A3–3410 / A3–3411 / A3–3412 : Humidity function is abnormal.
Remedy: 1) Remove the left cover. 2) If the harness and sensor are normal, replace the main board (JC92-02746A).

Description: Prepare new yellow toner cartridge. Shake toner cartridge and then install. Replace toner cartridge if the problem persists
Causes: Toner remained is 5 ~ 30% of its life.
Remedy: 1) Order new yellow toner cartridge because toner cartridge with level of “Low” will be exhausted soon.
