6.1.4.36 E194-4034 Sensor calibration error

<Cause>
Sensor calibration failed.
<Probable fault location>
Multi sensor, multi sensor base, head relay PCB, carriage relay PCB, or main controller PCB
<Countermeasure>
1) Retry calibration in the service mode.
2) Visual check
Remove foreign substances from the multi sensor base if any.
3) Replace the multi sensor.
4) Cable continuity check
If continuity of the cable between the multi sensor and the head relay PCB is abnormal, replace the cable.
5) Replace the head relay PCB.
6) Replace the carriage relay PCB.
7) Cable continuity check
If continuity of the cable between the carriage relay PCB and the main controller PCB is abnormal, replace the
cable.
8) Replace the main controller PCB.

6.1.5 Troubleshooting When Service Call Errors Occur

6.1.5.1 E141-4046 Recovery system's rotation count reached 50,000

<Cause>
The machine detected that the rotation count of the purge unit reached the specified value.
<Probable fault location>
Purge unit or main controller PCB
<Countermeasure>
1) Replace the purge unit.
After replacing the purge unit, select [SERVICE MODE]>[INITIALIZE]>[PARTS COUNTER] to reset the
counter.
2) Replace the main controller PCB.
