You can enable users to scan to email even when the MyQ server is offline. In such cases, users can log in to the terminal in the Offline mode and use the Panel Scan action to scan to emails. The terminal remembers the outgoing SMTP server and sends all emails directly to this server. Scanning to email in the Offline mode is supported by all the models that support embedded terminals.

To enable the feature:

Go to the printing device's Web UI and set your (customer) SMTP server's IP address in the SMTP Server Name field.

The email@myq.local and root@myq.local variables cannot be used in the Offline mode for scanning from the panel with these settings, because scanning is not done via the MyQ server.
