■ Error code 6801
The internal temperature sensor detected a temperature higher than the specified value.
<User Check>
- Decrease the room temperature.
- Place the machine away from a heater.
■ Error code 6901
Some fuser unit errors occurred at power-ON or upon recovery from sleep mode.
Error code 6902
After the error was detected at the fuser unit, power was turned ON again and the error is
being checked. (If power is turned OFF and ON after error code 6901 occurred, this code is
displayed for about 15 minutes.)
Cooling Down
Wait for a while
Step Cause Remedy
1 Internal temperature sensor
harness connection failure
Check the internal temperature sensor
harness connection and reconnect it.
2 Eject sensor PCB harness
connection failure
Check the eject sensor PCB harness
connection and reconnect it.
3 Eject sensor PCB failure Replace the eject sensor PCB ASSY.
4 Main PCB failure Replace the main PCB ASSY.
Fuser Error
Turn the power off, then on again. Leave the machine for 15 min.
Self-Diagnostic
Will Automatically Restart within 15 minutes.
Step Cause Remedy
1 Each harness connection failure
of the fuser unit
Check each harnesses connection of the
fuser unit and reconnect them.
2 Eject sensor PCB harness
connection failure
Check the eject sensor PCB harness
connection and reconnect it.
3 Fuser unit failure Replace the fuser unit.
4 Eject sensor PCB failure Replace the eject sensor PCB ASSY.
5 Low-voltage power supply PCB
failure
Replace the low-voltage power supply
PCB ASSY.
6 Main PCB failure Replace the main PCB ASSY.
Note:
Turn the power OFF. After checking that the fuser unit has cooled down, turn the power ON
again. After the machine is left as it is for about 10 minutes, this problem may be resolved.
