6.1.4.33 03862000-2E09 Insufficient roll media error

<Cause>
The machine detected that the remaining roll media was insufficient.
<Probable fault location>
Roll media, feed roller HP sensor, feed roller encoder film, feed roller encoder, or main controller PCB
<Countermeasure>
1) Replace the roll media.
2) Feed roller HP sensor
Check for normal operation. If the operation is abnormal, replace the feed roller HP sensor.
3) Replace the feed roller encoder film.
4) Replace the feed roller encoder.
5) Replace the main controller PCB.

6.1.4.34 03870001-2015 Cutter error

<Cause>
After roll media cutting, the multi-sensor could not detect the media end.
<Probable fault location>
Media, defective multi sensor, cutter unit, head relay PCB, or main controller PCB
<Countermeasure>
1) Media check
If there is any print or stain in the detection area on the media or the media size is not the specified one, replace the media.
2) Multi sensor
Select [SERVICE MODE]>[DISPLAY]>[SYSTEM]>[SIZE CR] to check the value read by the multi sensor. If the value is wrong, replace the multi sensor.
3) Visual check
Remove foreign substances from the multi sensor and cutter unit if any.
If the cutter unit is damaged or deformed, replace it.
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) Cable continuity check
If continuity of the cable between the head relay PCB and the carriage relay PCB is abnormal, replace the cable.
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 carriage relay PCB.
9) Replace the main controller PCB.
6.1.4.35 03900001-4042/03900001-4049 Firmware error
<Cause>
Firmware cannot be recognized.
The firmware is for another model.
<Probable fault location>
Firmware or main controller PCB
<Countermeasure>
1) Firmware
Check the version of the transferred firmware and the compatible models.
2) Replace the main controller PCB.

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) Cable continuity check
If continuity of the cable between the head relay PCB and the carriage relay PCB is abnormal, replace the cable.
7) Replace the carriage relay PCB.
8) Cable continuity check
If continuity of the cable between the carriage relay PCB and the main controller PCB is abnormal, replace the cable.
9 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
