Because of the known problems with the NFC functionality, I have tried to equip the printer after initial setup with the latest firmware. The firmware update started normally, but ended not correct. All LEDs will flash alternately since then. The printer is not to be used. Telephone support from Samsung could not help me. This selects the device from me would be produced in August 2013 and had installed the firmware of May-2013.
After the first unit I received another replacement device from Amazon. Unfortunately, with the same bad result!
