Have you done a simple restart of both the printer and your computer.
It seems the HP Software talking to the printer can get confused at times. In my case, at it's worst, it causes the HP Utility to quit.
My recent install of the latest firmware and driver has been much more stable. Check your versions, also.
Best of luck, TOM
What the hell is this set up doing? I can't find out on the website. Are they assigning more passes in the media preset Automatically... and an Option only for matte media or is my firmware screwed up?
