Screen Wiring

Power Off Before Operating

Before starting, completely shut down the printer and disconnect the power supply. Do not plug or unplug cables, organize connector wiring, or touch terminals while the device is powered on.

When connecting a TFT or HDMI screen, carefully confirm the orientation of the FPC cable to avoid device failure due to reverse connection.

Configuration Precautions

Please confirm the DIP switches on the back of the screen are set correctly: set to Resi for resistive screens and Cap for capacitive screens
The configuration file format must be key=value; there should be no spaces after the equals sign
Do not modify the configuration file format arbitrarily, otherwise the configuration will not take effect

After saving the configuration

Important Note

After modifying the configuration, please restart the system to apply the changes
