I just received this printer. The power button does not do anything. I plugged and unplugged power cord several times. After one of these times the panel lit up with the words PLEASE WAIT. After a few seconds a click noise was heard and the panel became unlit....you could still hear some fan(s) running. Again, the power switch does nothing so I unplug again and after several more attempts the panel stays lit, goes through the brief setup and I print a test page. I began printing some postcards and foolishly? waited 2 minutes between printing. The printer went to sleep and won't wake up. In control panel it will say that the printer is offline. This is just one of several issues with this new printer. Anyone have some ideas on what is happening? Thanks.
