Power down and prepare

• Carefully lay the printer down on a flat surface
• Loosen the 4 screws on the bottom case, and then open it

Remove the LCD hood

• Loosen the 4 screws that hold the hood in place
• Remove the hood from the printer

Identify the Touch Panel cable

• Locate the white ribbon cable which connects to the touch panel and the mainboard

Reseat the Touch Panel ribbon cable

• Open the cable clips on both the mainboard and the touch panel
• Detach the ribbon cable from both ends
• Check if the blue mark on the ribbon cable is facing upwards, then insert the cable all the way into the connectors
• Once the cable is fully inserted, lock the cable clips to secure the cable in place

Reassemble the printer 

• Reinstall the LCD hood 
• Put the bottom case back and tighten the 4 corner screws

Check the Touch Panel’s functionality

• Plug in the power cord and switch on the printer
• Verify if the touch panel is working properly

2. Updating firmware

Reflashing the firmware can solve touch panel issues caused by outdated software conflicts.

By doing so, you can make sure the printer's software is fully compatible with the touch panel, which can help to prevent issues such as unresponsiveness or erratic behavior.
