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) Cable continuity check
If continuity of the cable between the feed roller HP sensor or feed motor and the main controller PCB is
abnormal, replace the cable.
4) Replace the feed motor.
5) 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) Cable continuity check
If continuity of the cable between the valve open/closed detection sensor or valve motor and the main controller
PCB is abnormal, replace the cable.
5) Replace the main controller PCB.
