¶ Possible Causes
- Power cord plug is loose
- Fuse is damaged
- Touchscreen ribbon cable is loose
- Motherboard power supply port is loose
- Power supply has no output voltage
¶ Required Tools
- 2.0mm hex screwdriver
- Multimeter
- Phillips screwdriver
¶ Troubleshooting Steps
¶ 1.Check the Power Cord Plug
Inspect whether the power cord plug is loose and ensure it is fully inserted.

¶ 2.Check the Power Switch Indicator Light
Check if the power switch indicator light is on.

The fuse specification for Jupiter 2 is 10A 250V 5×20mm. If the fuse is damaged, you can purchase a matching fuse from a hardware store and replace it.
If the switch indicator light is on, proceed with the following troubleshooting steps.
¶ 3.Check the Motherboard Indicator Lights
Use the 2.0mm hex screwdriver to remove the five screws securing the right side panel and remove the panel.

Check whether the three indicator lights on the motherboard are on after powering up.

- If all three motherboard indicator lights are on, check the touchscreen ribbon cable.
- If none of the three motherboard indicator lights are on, check the motherboard power supply port.
¶ 4.Check the Touchscreen Ribbon Cable
Remove the tape at both ends of the touchscreen ribbon cable. Check whether both ends are loose and try re-inserting the ribbon cable.

The blue side of the touchscreen ribbon cable must face upward.
The ribbon cable must be aligned with the connector and not inserted at an angle.
The ribbon cable must be fully inserted into the connector (the exposed blue portion should be approximately 4.6mm wide)

- If the touchscreen ribbon cable is properly connected and the three motherboard indicator lights are on, the touchscreen may be damaged and needs to be replaced.
¶ 5.Check the Motherboard Power Supply Port
Turn off the power switch and unplug the power cord. Check whether the motherboard power supply terminal plug is loose.

¶ 6.Check Power Supply Output Voltage
Use the 2.0mm hex screwdriver to remove the five screws securing the left side panel.

Check whether the wire terminals are loose. If the wire terminals are loose, turn off the printer power switch
, unplug the power cord, and use a Phillips screwdriver to tighten the screws securing the wire terminals.
.png)
If the wire terminals are not loose, turn on the printer power switch. Use the multimeter in DC voltage mode to check whether the power supply has an output voltage of approximately 24V (if you do not have a multimeter, check whether the power supply indicator light is on).

- If there is 24V output at the power supply port, the motherboard or touchscreen may be damaged.
- If there is no 24V output at the power supply port / the power supply indicator light is off, the power supply may be damaged.
