■ Error code 0800
Error occurred in the internal temperature sensor.
■ Error code 0900
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.
Print Unable 08
Turn the power off and then back on again.
Step Cause Remedy
1 Harness connection failure of the
internal temperature sensor
Check the harness connection of the
internal temperature sensor and
reconnect it.
2 Eject sensor PCB harness
connection failure
Check the eject sensor PCB harness
connection and reconnect it.
3 Internal temperature sensor
failure
Replace the internal temperature sensor.
4 Eject sensor PCB failure Replace the eject sensor PCB ASSY.
5 Main PCB failure Replace the main PCB ASSY.
Print Unable 09
Turn the power off and then back on again.
Step Cause Remedy
1 Low-voltage power supply PCB
failure
Replace the low-voltage power supply
PCB ASSY. Reset the irregular power
supply detection counter after
replacement.
(Refer to "3.1 Reset of Irregular Power
Supply Detection Counter" in Chapter 4.)
2 Main PCB failure 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 sup-
ply PCB ASSY is replaced. For this reason, be sure to ask the user to rearrange the instal-
lation environment.
