The Machine Reports Error During Printing; Front And Back Side Limited Sensor Error; Error Code - Nuocai NC-DX0406 User Manual

3.3 Clean the encoder strip by alcohol if there is any ink, dust, oil or other dirty on it.
3.4 Check if the encoder strip is in the middle of the encoder strip sensor.
3.5 Check if the encoder strip is in the bars or not.
3.6 Replace the print head board(barely has this problem).
Mark: For this problem, the print head board receives the signal from the mainboard, but encoder strip sensor
couldn't read the encoder strip.

4. The machine reports error during printing.

4.1 Check if there's scratch on the encoder strip, if so, replace it.
4.2 Clean the encoder strip by alcohol if there is any ink, dust, oil or other dirty on it.
4.3 Check if the encoder strip is in the middle of the encoder strip sensor.
4.4 Check the screw which use to secure the X axis belt is tight or not, and the X axis belt is tight or loose.
4.5 Replace the mainboard cable.
4.6 Check if the temperature of the X axis motor is more than 50℃, if so reconnect the cable on the X axis motor.
Mark: For this problem, the encoder strip sensor can read the encoder strip, but will have wrong data to be read.
5. Move the cart to the middle of carriage beam and turn on the machine, cart moves to left size and then right
side, then towards and hit the left side fast and back to middle side and reports error.
5.1 Check if the zero position sense metal installed straight or not.
5.2 Change the black zero position limited sensor.
4.3 Change the balck zero position limited sensor cable.
4.4 Replace the print head board.

9.4 Front and back side limited sensor error

1. Disconnect and reconnect the limited sensor cable.
2. Replace the limited sensor.
1. Check if the limited sensor cable connects well or not.
2. Replace the mainboard.
3. Check if the limited sensor cable connects well or not.
4. Replace the mainboard.

9.5 Error code:

Error 1: PC driver problem, use the correct P Atool driver;
Error 2: The available printing area or time is very less, need to upgrade or authorize to have more printing time
or area;
Error 3: Available printing area or time is zero, need to upgreade or authorize to have more printing time or area;
Error 4: Cart black zero position limited sensor problem, repalce the limited sensor or its cable;
Error 5: Initizlization parameter problem, upgrade the P Atool driver;
Error 6: Cart hits on obstacle, check the impingement device;
Error 7: Checking if the P Atool is matches with the printer or not;
