MyQ TerminalPro requires an Embedded Lite terminal license, although you can use a full Embedded terminal license as well. The total number of MyQ TerminalPro terminals that can run at the same time is equal to the number allowed by the Embedded Lite terminal licenses and Embedded terminal licenses counted together. If the total number of licenses (Embedded terminal + Embedded Lite terminal) at the server is exhausted, the terminal cannot be activated and the Login failed / Access denied message is displayed each time a user tries to log in on the MyQ Touch Panel.
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, how to activate them, and how to extend the software assurance period, see the MyQ Print Server guide.
