This is an error that is not recognized by your Ultimaker S-line printer. In this case, there likely has been a communication error between the services that interact with the touchscreen. The exact origin of the error is unknown. However, the printer control mechanism may still be working, and so it may still be possible to control the printer using Ultimaker Cloud and Ultimaker Connect.
Due to the unknown source of this error, there is no straightforward solution for this error.
- Sometimes the error can be clicked away
- If the error remains on screen, power cycle the Ultimaker S3/S5 using the on/off switch. Wait until the printer has completely shut down before turning it on again
- Update the firmware to the latest stable version
