Display: Print Unable 08 Turn the power off and then back on again.
Description: Error occurred in the internal temperature sensor.
Remedy: 1 Connection failure of the internal temperature sensor harness Reconnect the internal temperature sensor harness. 2 Main PCB failure Replace the main PCB ASSY.

Display: Print Unable 09 Turn the power off and then back on again.
Description: Machine detected more than 100 times that supplied power was unstable.
Remedy: < User Check > - Turn OFF the power switch. After several seconds, turn ON the power again and check that this error is reset. 1 Low-voltage power supply PCB failure Replace the low-voltage power supply PCB unit. After replacing the low-voltage power supply PCB unit (Function code 88), and reset the irregular power supply detection counter of the low-voltage power supply PCB unit. 2 Main PCB failure Replace the main PCB ASSY. Note: The irregular power supply detection error (Error code 0900) of the low-voltage power supply PCB unit occurs when there is a large distortion in 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 unit is replaced. For this reason, be sure to ask the user to rearrange the installation environment.
