1. Check that the input components are normal, and ensure that the power box has 24V output.

2. The data cable is not plugged tightly, or the trolley voltage output by the mainboard is abnormal; Change the trolley board or main board.

3. Check the connecting line between the servo motor and the mainboard: the servo motor is abnormal.

1. Check the grating strip, decoder.

2. The trolley board or motherboard is broken; the motor connection wire is not securely connected or the motor is abnormal.

Check the sensor connection lines, the sensor.

1. Check that the power box has no 42V output, and the 42V insurance pipe of the motherboard is fused.

2. Check the print head data cable.

3. Replace the carriage board or print head board.

1. Replace the carriage board and print head board.

2. Check the print head data cable

The ink pump and solenoid valve are abnormal.

1. Check the connection lines, paper feed motor.

2. Replace the circuit board.

1. Reconfigure the IP address as required

2. Replace the network cable or Ethernet cable

3. Ensure that the cable connectors are not affected by the drag chain and become loose; replug the network cable and check if the connections are loose

Replace the carriage board.

1. Re-calibrate the stepper motor; when using different printing media, re-calibration of the stepper motor is required.

2. Adjust the spreader to make the paper pull evenly. Recalibrate the step with equal tension.

Re-calibrate the stepper motor or adjust the automatic compensation parameters within Montai.

1. Adjust the distance between the print head and the printing medium.

2. Check whether the output of the power supply box 42V is normal.

3. Recalibrate both vertical and bidirectional.

4. Adjust the printing speed.

5. Replace the print head driver board.

1. The print head's ink ejection is affected by the ambient temperature; it is necessary to maintain the working environment temperature within the normal range.

2. Replace with higher quality ink.

3. Ensure the ink supply pressure is normal and that there are no air leaks at the ink hoses and transition connectors.

4. Adjust the printing speed.

5. Replace the print head driver board.

1. The ink does not match the ICC profile well, or the print head nozzles are clogged.

2. Check whether the output of the power supply box 42V is normal.

3. Replace the print head driver board.

1. Re-tighten the cable.

2. Check the servo motor connection cables.

3. Inspect the grating position, check if the grating is scratched, the connection wire from the grating to the circuit board, the grating decoder.
