Error Codes List page 3

  • Code: 0800
  • Display: Print Unable 08 Turn the power off and then back on again.
  • Description: Error occurred in the internal temperature sensor.
  • Causes: 1 Harness connection failure of the internal temperature sensor 2 Eject sensor PCB harness connection failure 3 Internal temperature sensor failure 4 Eject sensor PCB failure 5 Main PCB failure
  • Remedy: Check the harness connection of the internal temperature sensor and reconnect it. Check the eject sensor PCB harness connection and reconnect it. Replace the internal temperature sensor. Replace the eject sensor PCB ASSY. Replace the main PCB ASSY.
  • Code: 0900
  • Display: Print Unable 09 Turn the power off and then back on again.
  • Description: Machine detected that supplied power was unstable.
  • Causes: 1 Low-voltage power supply PCB failure 2 Main PCB failure
  • Remedy: Replace the low-voltage power supply PCB ASSY. Reset the irregular power supply detection counter after replacement. Replace the main PCB ASSY. Note: The irregular power supply detection error (Error code 0900) occurs when there is a large distortion of the power supply voltage supplied to the machine. In this case, if the same power supply is used, the same error might occur again even if the low-voltage power supply PCB ASSY is replaced. For this reason, be sure to ask the user to rearrange the installation environment.
  • Code: 0A02
  • Display: Print Unable 0A Turn the power off and then back on again.
  • Description: The main fan failure was detected.
  • Causes: 1 Harness connection failure of the main fan 2 Harness connection failure of the high-voltage power supply PCB 3 Harness connection failure between the low-voltage power supply PCB and main PCB 4 Main fan failure 5 Low-voltage power supply PCB failure 6 High-voltage power supply PCB failure 7 Main PCB failure
  • Remedy: Check the harness connection of the main fan and reconnect it. Check the high-voltage power supply PCB harness connection and reconnect it. Check the harness connection between the low-voltage power supply PCB and main PCB, and reconnect it. Replace the main fan. Replace the low-voltage power supply PCB ASSY. Replace the high-voltage power supply PCB ASSY. Replace the main PCB ASSY.
  • Code: 0B01
  • Display: Print Unable 0B Turn the power off and then back on again
  • Description: Error in the high-voltage power supply PCB ASSY while the machine is in operation.
  • Causes: 1 Harness connection failure of the high-voltage power supply PCB 2 High-voltage power supply PCB failure 3 Main PCB failure
  • Remedy: Check the high-voltage power supply PCB harness connection and reconnect it. Replace the high-voltage power supply PCB ASSY. Replace the main PCB ASSY.
  • Code: 0B02
  • Display: Print Unable 0B Turn the power off and then back on again
  • Description: Error in the high-voltage power supply PCB ASSY in the ready state.
  • Causes: 1 Harness connection failure of the high-voltage power supply PCB 2 High-voltage power supply PCB failure 3 Main PCB failure
  • Remedy: Check the high-voltage power supply PCB harness connection and reconnect it. Replace the high-voltage power supply PCB ASSY. Replace the main PCB ASSY.
  • Code: 0C00
  • Display: Print Unable 0C Turn the power off and then back on again.
  • Description: Error occurred in the density sensor.
  • Causes: 1 Registration mark L PCB harness connection failure 2 Eject sensor PCB harness connection failure 3 Registration mark L PCB ASSY failure 4 Eject sensor PCB failure 5 Main PCB failure
  • Remedy: Check the registration mark L PCB harness connection and reconnect it. Check the eject sensor PCB harness connection and reconnect it. Replace the registration mark L PCB ASSY. Replace the eject sensor PCB ASSY. Replace the main PCB ASSY.
