The total number of embedded terminals that can run at the same time is equal to the number allowed by the embedded terminal licenses. If the number of embedded licenses at the server is exhausted, the terminal is deactivated. As a result, users cannot log in to this terminal and the Login failed/Internal error message appears on the terminal.
To regain access to the terminal, you can add a new license or deactivate one of the currently activated terminals and then, reactivate the printing device on the MyQ Web administrator interface.
For information on how to add embedded terminal licenses, activate them, and extend the software assurance period, see Licenses in the MyQ Print Server guide.
