• Code: E068-0000
• Description: There is an error in the high-voltage output to the separation charging assembly.
  An error (leakage) to the high-voltage output to the separation charging assembly is detected.
• Remedy: - Check if the transfer charging assembly and separation charging assembly are mounted properly. - Check if the connector (J722, J723, J730, J734) of the HV-DC PCB and the connector (J741, J742) of the HV-AC PCB are mounted properly. - Replace the HV-AC PCB. - Replace the separation charging assembly. - Replace the pre-transfer charging assembly.

• Code: E069-0000
• Description: There is an error in the high-voltage output to the transfer charging assembly.
  An error (leakage) is detected in the high-voltage output to the transfer charging assembly.
• Remedy: - Check if the transfer charging assembly and separation charging assembly are mounted properly. - Check if the connector (T701, J723, J730) of the HV-DC PCB is mounted properly and also check the wiring. - Replace the HV-DC PCB. - Replace the pre-transfer charging assembly.

• Code: E100-0000
• Description: The BD PCB is faulty.
  The BD signal does not arrive within 1 sec after the laser drive signal has been generated. Or, the BD signal does not arrive for 1 sec or more while the laser remains ON.
• Remedy: - Check if the BD PCB, laser driver PCB and DC controller are connected properly. - Replace the BD PCB. - Replace the laser scanner unit. - Replace the DC controller PCB.

• Code: E110-0000
• Description: The rotation of the laser scanner motor is faulty.
  The constant speed rotation signal (LM-RDY) does not arrive for 20 sec or more after the laser scanner motor (M4) drive signal has been generated.
• Remedy: - Check if the connector (J762) of the laser scanner motor driver PCB is mounted properly. - Check if the connector (J503) of the DC controller PCB is mounted properly. - Replace the laser scanner unit. - Replace the DC controller PCB.

• Code: E111-0000
• Description: The rotation of the laser motor cooling fan is faulty.
  The lock signal arrives for 5 sec or more although the laser motor cooling fan (FM1) is being driven.
• Remedy: - Check if there is no foreign material in the rotation assembly of the laser motor cooling fan. - Check if the connector (J503) of the relay PCB is mounted properly. - Replace the laser motor cooling fan. - Replace the DC controller PCB.

• Code: E121-0001
• Description: The rotation of the laser cooling fan (1/2) is faulty.
  The lock signal arrives for 5 sec or more although the laser cooling fan 1 (FM3) is being driven.
• Remedy: - Check if there is no foreign material in the rotation assembly of the laser cooling fan 1. - Check if the connector (J503) of the relay PCB is mounted properly. - Replace the laser cooling fan 1. - Replace the DC controller PCB.

• Code: E121-0002
• Description: The rotation of the laser cooling fan (1/2) is faulty.
  The lock signal arrives for 5 sec or more although the laser cooling fan 2 (FM5) is being driven.
• Remedy: - Check if there is no foreign material in the rotation assembly of the laser cooling fan 2. - Check if the connector (J503) of the relay PCB is mounted properly. - Replace the laser cooling fan 2. - Replace the DC controller PCB.

• Code: E202-0000
• Description: There is an error in the detection of the scanner home position.
  Scanner home position cannot be detected within a specific period of time after the power switch is turned on or the Start key is pressed.
• Remedy: Caution No code will be indicated. The keys will be locked. You can check the code in service mode (COPIER>DISPLAY>ERR). - Check if the scanner motor is connected properly, and replace the scanner motor if necessary. - Check if the connector (J1720) of the relay PCB is mounted properly. - Replace the scanner home position sensor. - Replace the reader controller PCB.
