Samsung SLM4583FX

• Code: A2–1210, A2–2110
• Display: Fan Failure: #A2-xxxx. Turn off then on. Call for service if the problem persists
• Description: SMPS or Fuser or LSU or Deve fan is not operational.
• Remedy: NOTE • SMPS fan error : A2–1210 • Main(Fuser) fan error : A2–2110 • LSU fan error : A2–2410 • Deve fan error : A2–2610 1) Turn the machine off. 2) Check if the corresponding fan connector is connected correctly 3) If the connection is OK, Enter SVC mode and execute fan test. (Diagnostics > Engine Diagnostics > Engine Test Routines) 4) If the fan is not operational, measure the fan power. a) If 24V power is generated, replace the defective fan. • SMPS fan : JC31–00153A • Main(Fuser) fan : JC31–00088A • LSU fan : JC31–00086A • Deve fan : JC31–00086A b) If 24V power is not generated, • Measure the 24V power on the SMPS board. If the SMPS board(JC44-00092C (220V) / JC44-00091C (110V)) is defective, replace it. • If the SMPS board is normal, replace the main board(JC92–02722A). 5) If the fan operation is normal but the error persists, a) Check the yellow line signal with DVM. b) Check fan operation as connected or disconnected. • If the Lock signal is 0V continually, check the harness. If the harness is OK, replace the main board. • If the signal value is different from the table above, replace the fan.

• Code: A3–3212
• Display: Sensor Failure: #A3-3212. Turn off then on. Call for service if the problem persists
• Description: Inner temperature sensor is defective.
• Remedy: 1) Enter SVC mode. Execute sensor test to check its operation. (Diagnostics > Engine Diagnostics > Engine Test Routines) 2) Measure the resistance value of the connector at both ends. If the value is not in 47.5K - 52.5K (@ 25C), replace the inner temp sensor(1404-001417). 3) If the sensor is normal, replace the main board(JC92.02722A).

• Code: A3–3312, A3–3320
• Display: Sensor Failure: #A3-3312. Turn off then on. Call for service if the problem persists The room temperature is not suitable for this set use. Please adjust room temperature
• Description: Outer temperature/humidity sensor is defective.
• Remedy: 1) Enter SVC mode. Execute sensor test to check its operation. (Diagnostics > Engine Diagnostics > Engine Test Routines > Outer Temperature) 2) Measure the resistance value of the connector at both ends. If the value is not in 47.5K - 52.5K(@ 25C), replace the outer temperature/humidity sensor(JC32-00005A). 3) If the harness and sensor are normal, replace the main board(JC92.02722A).

• Code: A4-1110
• Display: Lamp Failure: #A4-1110. Open the door, then close it. Call for service if the problem persists
• Description: Erase Lamp does not turn on.
• Remedy: 1) Enter SVC mode. Execute the erase lamp test. (Diagnostics > Engine Diagnostics > Engine Test Routines > Erase Lamp) 2) If the erase lamp does not turn on, replace it(JC92-02373A).

• Code: C1–1110, C1–111A
• Display: Prepare new toner cartridge Shake toner cartridge and then install. Replace toner cartridge if the problem persists
• Description: Toner cartridge is almost empty.
• Remedy: 1) Open the front cover. 2) Remove the toner cartridge. 3) Shake the toner cartridge horizontally to distribute the toner evenly inside the cartridge. 4) Reinstall the toner cartridge. 5) Close the front cover. 6) Prepare new toner cartridge because it will be exhausted soon.
