1) Suction fan
Select [SERVICE MODE]>[FUNCTION]>[PLATEN FAN] to check the suction fan for normal operation. If
the operation is abnormal, replace the suction fan.
2) Cable continuity check
If continuity of the cable between the suction fan and the main controller PCB is abnormal, replace the cable.
3) Replace the main controller PCB.
6.1.4.17 03130031-2F20/03130031-22/03130031-2F23/03130031-2F28/03130031-2F2D
Defective sensor in purge unit
<Cause>
The pump cam sensor in the purge unit could not detect the home position of the purge motor within the
specified time.
<Probable fault location>
Purge unit or main controller PCB
<Countermeasure>
1) Cable continuity check
If continuity of the cable between the pump cam sensor or purge motor and the main controller PCB is abnormal,
replace the cable.
2) Replace the purge unit.
3) Replace the main controller PCB.

6.1.4.18 03130031-2F25 Carriage home position error

<Cause>
The carriage home position could not be detected within the specified time.
<Probable fault location>
Carriage stopper, linear scale, linear encoder, or main controller PCB
<Countermeasure>
1) Visual check
Remove foreign substances from the carriage stopper, linear scale, and linear encoder if any.
2) Replace the linear scale.
3) Replace the linear encoder.
4) Replace the main controller PCB.

6.1.4.19 03130031-2F26/03130031-2F27 Carriage motor error

<Cause>
The carriage did not operate because the carriage motor was overloaded due to a physical cause such as a jam.
The carriage motor did not reach the specified speed within the specified time.
<Probable fault location>
Carriage pathway, carriage rail, carriage belt, linear scale, linear encoder, carriage motor, carriage relay PCB,
or main controller PCB
<Countermeasure>
1) Carriage pathway check
Remove foreign substances (jammed paper) from the carriage pathway if any.
2) Carriage rail
Visually check whether the carriage rail is dirty. If the carriage rail is dirty, clean it using rail cleaner.
3) Carriage belt
Visually check whether the carriage belt is loose. If the carriage belt is loose, remove it and then reinstall it.
4) Replace the linear scale.
5) Replace the linear encoder.
6) Cable continuity check
If continuity of the cable between the linear encoder and the carriage relay PCB is abnormal, replace the cable.
