Their support sucks my S4 been broken longer than I've gotten to use it. Email reply are every other day at best. During the self test I get an error that the screen not connected. They sent me a screen that took 20 business days to arrive. I also bought my own screen and I get the same error. I keep telling them it's the main board but they haven't shipped a new board out yet. I really regret even getting this printer.
