I just got the printer this week. I got it hooked up to wi-fi finally, and uploaded the most recent update. I'd run a test print prior, and had no issues. I went to run another test print after the update, and once I get to the screen that shows all the settings and has the green start button, the touchscreen becomes unresponsive, like the system froze. Has anyone else experienced this issue, and if so, do you know of any fixes for this?
