- Regular Inspection: Periodically check all screws and connections to ensure they are secure.
7. Troubleshooting
- Uneven Heating: Ensure the heating element is clean and free of debris. Verify that the pressure is evenly distributed across the platen. The machine features double tube heating for uniform temperature.
- Design Not Transferring: Check that the temperature and time settings are correct for your material. Ensure sufficient pressure is applied. Verify that the heat transfer material is compatible with the substrate.
- Machine Not Powering On: Check the power cord connection and the wall outlet. Ensure the main power switch is in the 'ON' position.
