Restricting the Remote UI
You can set whether to enable the Remote UI to operate the machine and change settings. If you want to access the machine more securely from a web browser, enable TLS (Transport Layer Security) for encrypted communications. You can also set the Password so that general users are required to enter the Password to log in to the Remote UI.

|
Changes made to RUI settings become effective when the machine is restarted. To restart the machine, turn it OFF, wait at least 10 seconds, and then turn it ON. For instructions on how to turn the machine ON and OFF, see Chapter 2, “Before You Start Using the Machine,” in the User’s Guide.
