<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) Media loading position check
If the media loading position is wrong, load the media again.
3) Visual check
Remove foreign substances from multi sensor if any.
4) 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.
5) Cable continuity check
If continuity of the cable between the multi sensor and the head replay PCB is abnormal, replace the cable.
6) Replace the head relay PCB.
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.
6.1.4.2 03010000-200D Cut media end error
0014-0977
<Cause>
When cut media was fed by the specified length, the media sensor could not detect the trailing edge of the cut
media.
During printing, the media sensor detected the trailing edge of the cut media at the position different from that
detected during cut media feed.
<Probable fault location>
Paper path, media sensor, or main controller PCB
<Countermeasure>
1) Visual check
Remove foreign substances from the paper path and media sensor if any.
If the paper feed surface or moving part of the paper path is damaged or deformed, replace the paper path.
2) Media sensor,
Check the media sensor for normal operation. If the operation is abnormal, replace the media sensor.
3) Cable continuity check
If continuity of the cable between the paper detection sensor and the main controller PCB is abnormal, replace
the cable.
4) Replace the main controller PCB.
6.1.4.3 03010000-2016 Paper feed/delivery jam error
0014-0981
<Cause>
During paper feed or delivery, paper jammed or paper was fed improperly.
During printing, paper was fed out of the way.
<Probable fault location>
Paper path, media sensor, or main controller PCB
<Countermeasure>
1) Visual check
Remove foreign substances from the paper path and media sensor if any.
If the paper feed surface or moving part of the paper path is damaged or deformed, replace the paper path.
2) Media sensor
Select [SERVICE MODE]>[I/O DISPLAY] to check the media sensor for normal operation. If the operation is
abnormal, replace the media sensor.
3) Cable continuity check
If continuity of the cable between the media sensor and the main controller PCB is abnormal, replace the cable.
4) Replace the main controller PCB.
