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) Replace the purge unit.
2) 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) Replace the carriage motor.
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.

6.1.4.20 03130031-2F2A Feed roller home position error

<Cause>
During power-on, the feed roller HP sensor could not detect that the reference of Scale that exists on encoder film area color change from transparent to black.
<Probable fault location>
Encoder film, feed roller HP sensor, feed motor, or main controller PCB
<Countermeasure>
1) Visual check
If the feed roller encoder film is damaged, replace it. Remove foreign substances from the feed roller encoder film if any.
2) Feed roller HP sensor
Select [SERVICE MODE]>[I/O DISPLAY] to check for normal operation. If the operation is abnormal, replace the feed roller HP sensor.
3) Replace the feed motor.
4) Replace the main controller PCB.

6.1.4.21 03130031-2F3A valve open/close error

<Cause>
When the ink supply valve opened or closed, valve open/closed detection sensor could not detect the valve cam rotation.
<Probable fault location>
Valve open/closed detection sensor, valve motor, or main controller PCB
<Countermeasure>
1) Visual check
Remove foreign substances from the motor, gear, and sensor of the valve open/close mechanism if any.
2) Valve open/closed detection sensor
Select [SERVICE MODE]>[I/O DISPLAY] to check for normal operation. If the operation is abnormal, replace the valve open/closed detection sensor.
3) Valve motor
Select [SERVICE MODE]>[FUNCTION]>[INK VALVE] to check for normal operation. If the operation is abnormal, replace the valve motor.
4) Replace the main controller PCB.
6.1.4.22 03800200-2802/03800400-2803/03800300-2801 Printhead error
<Cause>
Improper installation of the printhead was detected.
A checksum error was detected in the EEPROM of the printhead.
