I have tried the applicable steps (i.e., can't copy, no airprint), and no luck. However, I replaced the Ethernet cable, and it worked - for one copy. I was able to print a self test page, but it still showed no connection. I tried to print other pages, but no luck. I moved the cable on the switch to different ports, patch board locations, new cable again - still nothing. I used the MacBook Pro with no luck - neither could find the printer. The green status light, next to the Ethernet cable entering the printer, is always a solid green. The yellow light flashes intermittently, as I believe it should. I bypassed the power strip and went directly to a different outlet.
