■ Error code 0800
Print Unable 08
Turn the power off and then back on again.
Error occurred in the internal temperature sensor.
Step
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
■ Error code 0900
Print Unable 09
Turn the power off and then back on again.
Machine detected that supplied power was unstable.
<User Check>
- Turn the power OFF and ON again after several seconds to check if the error code
disappears.
Step
1 Low-voltage power supply PCB
failure
2 Main PCB failure
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 sup-
ply PCB ASSY is replaced. For this reason, be sure to ask the user to rearrange the instal-
lation environment.

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.
Remedy
Replace the low-voltage power supply
PCB ASSY. Reset the irregular power
