I quote here only for me disturbing things on, anything like device, WLAN, etc. works fine. If the printer is turned off and it turns him on the power button or wakes wireless printer takes a long time until the printer is ready for operation and outputs the pressure. During this time he also rattles very long, that's too bad and very disturbing. These operating noises occur when you turn off, as if the unit still makes an adjustment. The option in the printer which is to make the sounds quieter, has brought nothing with me, I hear no difference. Too bad, otherwise it would be 5 star
