Steps to resolve manual or smart connection failure between printer and curing/cleaning unit:
- Connect the printer to a strong 2.4GHz Wi-Fi and retry;
- On the curing/cleaning unit, perform a network reset and restart, then restart the printer and confirm the connection in the newly prompted dialog (wait ~10s after network reset);
- Wait until the curing/cleaning unit is idle before performing smart connection;
- Retry after switching the hotspot.
