Samsung Scanner Server is not running

[dex]

Fresh Installation of Lubuntu 16.04.
i have installed through synaptic package manager following packages as in attachment. Scanner and printer is working by simple scan , and printer as well.
But I have a problem with Samsung server which is not running When I click check Server Status, even after restart server click.
When I click view log nothing is done.

Where are the logs files?
