LaserJet Pro MFP M428fdn becomes unresponsive during sleep mode

Hi there, I have problem with my few days old device. It sometime becomes unresponsive during sleep mode. It does not accept new print jobs and also an input from non responding black touch screen. First press of power button is without reaction, a second press turns off the device. In this strangely state of device, I am able to ping device and also access Embedded Web Server, but that is all. Power off and power on of device is only solution to continue in work.

The OS driver is configured to use standart TCP/IP port. Firmware version is 002.2014A.00.

I have catched mentioned behaviour on video https://www.youtube.com/watch?v=p36dxP_lRgQ.
