6.1.3.24 03800501-280D/03800502-280E Defective printhead nozzle
0013-7178
<Cause>
Many non-discharging nozzles were detected on printhead R.
Many non-discharging nozzles were detected on printhead L.
<Probable fault location>
Printhead, head management sensor, or main controller PCB
<Countermeasure>
1) Clean the printhead.
2) Replace the printhead.
3) Replace the head management sensor.
4) Replace the main controller PCB.
6.1.3.25 03841201-2816/03841201-2817/03841101-2818/03841001-2819/03841001-281B Maintenance cartridge error
0013-7179
<Cause>
The maintenance cartridge is full.
The maintenance cartridge does not have the free space for various types of cleaning.
No maintenance cartridge is installed.
The EEPROM of the maintenance cartridge is abnormal.
A maintenance cartridge ID error occurred.
<Probable fault location>
Maintenance cartridge, maintenance cartridge relay PCB, or main controller PCB
<Countermeasure>
1) Replace the maintenance cartridge.
2) Replace the maintenance cartridge relay PCB.
3) Replace the main controller PCB.
6.1.3.26 03010000-2820/03010000-2821/03010000-2822/03010000-2823/03130031-2F32/03010000-2F33/ Adjustment error
0013-7180
<Cause>
Auto head alignment selected from the user menu could not be carried out because the alignment pattern read result was NG.
Auto LF adjustment selected from the user menu or in the service mode could not be carried out because the adjustment pattern read result was NG.
Decentering correction selected in the service mode cannot be carried out because the correction pattern read result was NG.
Auto LF adjustment selected from the user menu or in the service mode could not be carried out because the head check pattern read result was NG.
Optical axis adjustment selected in the service mode cannot be carried out because the adjustment pattern read result was NG.
When adjustment has been carried after selecting [SERVICE MODE]>[ADJUST]>[PRINT PATTERN]>[OPTICAL AXIS] or [SERVICE MODE]>[AD-
JUST]>[PRINT PATTERN]>[LF TUNING] in the service mode, check that photo glossy paper is used.
<Probable fault location>
Operation method, printhead, multi sensor, head relay PCB, carriage relay PCB, or main controller PCB
<Countermeasure>
1) Check whether the media type selected on the operation panel is the same as the type of the media used to print the adjustment pattern. If they are different, retry
adjustment using the media of the type selected on the operation panel.
2) If ink bleeds greatly, change the media.
3) Carry out head cleaning, and retry adjustment. If the adjustment result is poor, replace the printhead.
4) Cable continuity check
If continuity of the cable between the multi sensor and the head relay PCB is abnormal, replace the cable.
5) Cable continuity check
If continuity of the cable between the head relay PCB and the carriage relay PCB is abnormal, replace the cable.
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 multi sensor, and then retry adjustment.
8) Replace the head relay PCB.
9) Replace the carriage relay PCB.
10) Replace the main controller PCB.
6.1.3.27 03130031-260E Gap detection error
0013-7224
<Cause>
A detection error occurred due to damaged hardware, uncorrected gap, or damaged correction data.
<Probable fault location>
Multi sensor, head relay PCB, carriage relay PCB or main controller PCB
<Countermeasure>
1) Cable continuity check
If continuity of the cable between the multi sensor and the head relay PCB is abnormal, replace the cable.
2) Replace the multi sensor.
3) Cable continuity check
If continuity of the cable between the head relay PCB and the carriage relay PCB is abnormal, replace the cable.
4) Replace the head 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 carriage relay PCB.
7) Replace the main controller PCB.
6.1.3.28 03130031-260F Gap adjustment error
0013-7228
<Cause>
Gap reference surface error (This error occurs only in the service mode.)
