## Troubleshooting

### Red light problem

The printer has a switch that is triggered when the top cover is closed. Because of heat the switch is sometimes not closed even if the cover is closed and that results in the indefinite red light problem. To fix unscrew the back cover and bend the metal on the switch so that it closes correctly.
