<Probable fault location>
Multi sensor reference plate, multi sensor, head relay PCB, carriage relay PCB or main controller PCB
<Countermeasure>
1) Replace the multi sensor reference plate.
2) Cable continuity check
If continuity of the cable between the multi sensor and the head relay PCB is abnormal, replace the cable.
3) Replace the multi sensor.
4) Cable continuity check
If continuity of the cable between the head relay PCB and the carriage relay PCB is abnormal, replace the cable.
5) Replace the head relay PCB.
6) Cable continuity check
If continuity of the cable between the carriage relay PCB and the main controller PCB is abnormal, replace the cable.
7) Replace the carriage relay PCB.
8) Replace the main controller PCB.

0013-6984
<Cause>
When the suction fan was driven, the lock signal was detected for more than the specified time.
<Probable fault location>
Suction fan or main controller PCB
<Countermeasure>
1) Suction fan
2) Replace the main controller PCB.
6.1.3.33 03030000-2E21 IEEE1394 Error
0013-7192
<Cause>
The IEEE1394 interface is faulty.
<Probable fault location>
IEEE1394 interface board or main controller PCB
<Countermeasure>
1) Turn off the printer, and then turn it on again.
2) IEEE1394 interface board
Remove the IEEE1394 interface board, install it again, and then turn on the printer. If the trouble persists, replace the IEEE1394 interface board.
3) Replace the main controller PCB.
