• Description: The cassette cannot work. The cassette cannot work.
• Causes: Pressure plate arm, cassette cam sensor, cassette motor, or main controller PCB
• Remedy: 1. Visual check If the pressure plate arm is abnormal, replace the pressure plata arm. 2. Cassette cam sensor Select [SERVICE MODE]>[I/O DISPLAY] to check for normal operation, If the operation is abnormal, replace the valve motor. 3. Cable continuity check If continuity of the cable between the cassette cam sensor, cassette motor and the main controller PCB is abnormal, replace the cable. 4. Replace the cassette motor. 5. Replace the main controller PCB.

• Code: 03130031-2F2E
• Description: Roll drive time-out error. The roll cam sensor home position in roll feed unit could not be detected within the specified time.
• Causes: roll cam drive unit, roll cam sensor, roll motor, Connector, roll feed unit PCB, or main controller PCB
• Remedy: 1. Visual check If the gear in roll cam drive unit is abnormal, replace the gear. 2. Roll cam sensor Select [SERVICE MODE]>[I/O DISPLAY] to check for normal operation. If the operation is abnormal, replace the roll cam sensor. 3. Cable continuity check If continuity of the cable between the roll cam sensor, roll motor and roll feed unit PCB is abnormal, replace the cable. 4. Replace the roll motor. 5. Replace the roll feed unit PCB. 6. Cable continuity check If continuity of the cable between the roll feed unit PCB and main controller PCB is abnormal, replace the cable. 7. Replace the connector. 8. Replace the main controller PCB.

• Code: 03130031-2F32
• Description: Adjustment error. Auto head alignment selected from the user menu could not be carried out because the alignment patter 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 patter 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 patter read result was NG.
• Causes: Operation method, printhead, multi sensor, carriage PCB, or main controller PCB
• Remedy: 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. Replace the multi sensor, and then retry adjustment. 5. Cable continuity check If continuity of the cable between the multi sensor and the main controller PCB is abnormal, replace the cable. 6. Replace the carriage PCB. 7. Cable continuity check If continuity of the cable between the carriage PCB and the main controller PCB is abnormal, replace the cable. 8. Replace the main controller PCB.

• Code: 03130031-2F3A
• Description: Valve open/close error. When the ink supply valve opened or closed, valve open/closed detection sensor could not detect the valve cam rotation.
• Causes: Valve open/closed detection sensor, valve motor, or main controller PCB
• Remedy: 1. Visual check Remove foreign substances from the motor,gear, and sensor of the valve open/close mechanism if any. 2. Valve open/close detection sensor Select [SERVICE MODE]>[I/O DISPLAY] to check for normal operation. If the operation is abnormal, replace the valve open/close 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/close detection sensor, valve motor and main controller PCB is abnormal, replace the cable. 5. Replace main controller PCB.

• Code: 03180003-2E22
• Description: MIT error. When set to cassette paper feed "No" with MIT, the job of the cassette specification was received.
• Causes: Main controller PCB
• Remedy: 1. Replace the main controller PCB.

• Code: 03180101-2E17
• Description: Cassette uninstallation. The cassette has come off.
• Causes: Cassette detection sensor or main controller PCB
• Remedy: 1. Cassette detection sensor Select [SEVICE MODE]>[I/O DISPLAY] to check for normal operation. If the operation is abnormal, replace the cassette detection sensor. 2. Cable continuity check If continuity of the cable between the cassette detection sensor and the main controller PCB is abnormal, replace the cable. 3. Replace the main controller

• Code: 03800200-2802
