Waynepice56 0 Report post Posted June 1, 2015 We started printing documents today on our Epson XP-820 All in One printer and the print quality is awful. The only thing that has changed within the last 48 hours was a download of firmware we did yesterday. It still recognizes all of the cartridges but the print quality has been drastically affected. Blacks fade in and out, nozzle checks show many lines missing and broken on the black output. I am not using Epson cartridges so this is where I think we're having the issue. How do I get back to the previous firmware when all was working fine? Many thanks, Allspice56 Share this post Link to post Share on other sites
