newly arrived Samsung CLX-4195FW greeted me with just blue samsung’s logo on the white background presented on the front LCD screen; at the same time printer correctly acquired IP via DHCP and i could access the management interface via the network.
i’ve called Samsung 3x and luckily enough at the 3rd attempt i spoke with someone who helped me. i was told to power off the device and press the stop/clear button [or power button – i dont remember which one] for 30 seconds], then release it and connect the device back to the power. that did the trick – device booted completely this time presenting me with menu on the touch screen. most probably pressing one of those buttons does some sort of factory defaults reset/nvram flush.
