Before printing or when encountering an issue, you may need to check the status of your Sonic Mini 4K's LCD screen. This is to ensure that both the UV lights and the 6.1” Mono-LCD screen are functioning properly. We will guide you through the steps of performing an LCD test and how you can read it:

Performing a Dry Print
Sometimes issues such as flickering or glitches may still be difficult to be identified after performing the above tests. This is why Dry Prints are helpful. A dry print is when you run a test print without placing the resin vat and the building plate. It is to check whether the LCD is flickering or not.
- Remove the resin vat and the building plate.
- Perform any test print of your choice.
- Inspect to see if the image shown on the LCD is the same as on the touch panel.
