• Code: A3-2110, A3-2113, A3-2210
• Display: ID control has failed. Check the CTD sensor(A3-2110) The CTD sensor is dirty. Please clean it with soft cloth or paper(A3-2113) ID control has failed. Check the CTD sensor(A3-2210)
• Description: CTD sensor is defective or CTD sensor calibration is abnormal.
• Remedy: 1) Open the side cover. 2) Open the ACR module. 3) Move the shutter to the right manually. 4) Close the side cover. 5) Check if the CTD sensor window is contaminated. If yes, clean the window with soft cloth. 6) If the problem persists, replace the CTD sensor(JC32-00012A and JC32-00014A).

• Code: A3-3111, A3-3112
• Display: Sensor Failure: #. Turn off then on. Call for service if the problem persists.
• Description: The NC sensor in the fuser unit is defective. / The sensor signal is abnormal due to a defective harness.
• Remedy: . 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. 1) Enter SVC mode. Execute sensor test to check the sensor operation. (Diagnostics > Engine Diagnostics > Engine Test Routines) . 109-0000 : Fuser Temperature A . 109-0010 : Fuser Temperature B 2) Remove the fuser unit and disassemble the NC thermistor. 3) Measure the resistance value of the thermistor. . Side : 1404.001718 . Center : 1404.001719 If the measured value is out of 307KOm - 430KOm at 25C, replace the thermistor. 4) Install the fuser unit after replacing the thermistor. 5) If the thermistor is normal, replace the harness between the fuser unit and main board. (JC39-01746A) 6) If the error persists, replace the fuser unit(JC91-01121A(220V) / JC91-01120A(110V)). 7) If the error persists after replacing fuser unit, replace the main board(JC92-02516A).
