During printing, ink tank cover switch has detected the open state of the ink tank.
<Probable fault location>
Operation method, ink tank cover, ink tank cover switch, main controller PCB
<Countermeasure> 1) Operation check
Close the ink tank cover surely.
2)Replace the ink tank cover unit.
3)Replace the main controller unit.
6.1.3.5 03031000-2E11 Carriage cover sensor error
<Cause>
The carriage cover sensor detected that the carriage cover was opened with the upper cover locked.
<Probable fault location>
Operation method, carriage cover sensor, carriage relay PCB, or main controller PCB
<Countermeasure> 1) Operation check
Close the carriage cover tightly.
2) Visual check
If the carriage cover is damaged or deformed, replace it.
3) Carriage cover sensor
check the carriage cover sensor for normal operation. If the operation is abnormal, replace the carriage cover sensor.
4)Replace the carriage relay PCB.
5)Cable continuity check
If continuity of the cable between the carriage relay PCB and the main controller PCB is abnormal, replace the cable. 6) Replace the main controller PCB.
6.1.3.6 03031000-2E12 Defective paper release lever
<Cause>
The pressure release switch detected that the paper release lever was opened with the upper cover locked.
<Probable fault location>
Operation method, pressure release switch, or main controller PCB
<Countermeasure> 1) Operation check
Close the paper release lever fully.
2) Visual check
If the paper release lever is damaged or deformed, replace it.
3) Pressure release switch
check the pressure release switch for normal operation. If the operation is abnormal, replace the pressure release switch. 4) Replace the main controller PCB.
6.1.3.7 03010000-2016/03010000-2E27 Paper feed error
<Cause>
During paper feed or delivery, paper jammed or paper was fed improperly.
During printing, paper was fed out of the way.
During paper feed, delivery or printing, the feed motor has gone out of synchronization.
<Probable fault location>
Paper path, media sensor, feed roller encoder, feed roller HP sensor, feed motor, feed roller, 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 for normal operation. If the operation is abnormal, replace the media sensor.
3) Replace the feed roller sensor unit
Check for normal operation. If the operation is abnormal, replace the feed roller sensor unit.
4)Replace the feed motor.
5)Replace the feed roller.
6)Replace the main controller PCB.
6.1.3.8 03010000-200D Cut media end error
<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, feed roller encoder, feed roller HP sensor, feed motor, feed roller, 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) Replace the feed roller sensor unit
Check for normal operation. If the operation is abnormal, replace the feed roller sensor unit.
4)Replace the feed motor.
5)Replace the feed roller.
