4. Replace the system controller.

6.1.4.26 E02D06/ Ink supply valve switching error

<Cause>

The valve cam sensor could not detect valve cam rotation during switching of the ink supply valve.

Valve motor unit, engine controller, system controller

1. Visual check

Check if there are any foreign objects adhering to the motor, gears, and sensors of the valve motor unit, and remove if any abnormalities are found.

2. Valve motor unit

Check operation by using SERVICE MODE>FUNCTION>INK VALVE, and replace if there are any abnormalities.

3. Cable connection check

Replace the cables between the valve motor and valve cam sensor and the engine controller if any abnormalities are found in the cable connections.

4. Replace the engine controller.

5. Replace the system controller.

6.1.4.27 E02D07/ Feed roller home position sensor error

<Cause>

During power on, the feed roller home position sensor could not detect the change from white to black of the reference area from the scale at the encoder slit.

Encoder slit, feed roller home position sensor, feed motor, engine controller, system controller

1. Visual check

Remove any scratches or adhered foreign objects from the encoder slit.

2. Feed roller home position sensor

Check operation using SERVICE MODE>I/O DISPLAY, and replace if anything does not function normally.

3. Cable connection check

Replace the cable between the feed roller home position sensor and engine controller if the connection is not functioning normally.

4. Cable connection check

Replace the cable between the feed motor and engine controller if the connection is not functioning normally.

5. Replace the engine controller.

6. Replace the system controller.

6.1.4.28 E02D09/ Suction fan lock error

<Cause>

Lock signal is detected longer than prescribed interval while driving the suction fan.

Suction fan, engine controller and system controller

1. Suction fan

Check operation by using SERVICE MODE>FUNCTION>PLATEN FAN, and replace if there are any abnormalities.

2. Cable connection check

Replace the cable connecting the suction fan and engine controller if the connection is not functioning properly.

3. Replace the engine controller.

4. Replace the system controller.

6.1.4.29 E02E01/ E02E05/ E02E06/ Carriage motor error

<Cause>

This is displayed when a jam or other physical problem puts an excessive load on the carriage motor so that the carriage could not operate.

This is displayed when the carriage motor could not reach the prescribed speed within the prescribed time.

Foreign object in carriage movement path, carriage rail, carriage belt, linear scale, linear encoder, carriage motor, engine controller, system controller

1. Carriage movement path check

Remove any foreign objects (jammed sheet) in the carriage movement path.

2. Carriage rail

Use rail cleaner to clean the carriage rails if a visual check reveals that they are dirty.

3. Carriage belt

If a visual check reveals slack in the carriage belt, remount the belt.

4. Replace the linear scale.

5. Replace the linear encoder.

6. Replace the carriage motor.

7. Cable connection check

Replace the cable between the carriage motor and engine controller if the connection is not functioning normally.

8. Replace the engine controller.
