Since I often print in duplex mode, was for me only a printer with appropriate option in question. My old HP 7280 (with CISS) was unfortunately on after many years. So I informed me at various test sites and came finally to Epson XP 850, as it unfortunately no comparable HP gave !? Now it is finally time that I send the printer to Epson after he no longer turns on. Purchase date is the 12.28.13 !! It began shortly after the initial installation so that has caused at every second or third double-sided printing, the printer after printing the front during re-feeding paper jam. Annoying, but quickly resolved by removing the rear cover, the side but was lost in the continuous pressure and had to be reprinted manually. Then it was often the case that the power button after some sideways, responded high and depressing. And finally, the overflow ink tank is full (after 3 months), since the print head quality is either bad or the replacement ink dud (I think not honestly). Keyword printhead cleaning! All in all, in this quarter more anger and frustration than pleasure Print !!!!
