Even if the paper tray has enough papers in it, it says "Out of paper, load paper ...". I have wasted hours on this stupid issue. Seems as if some kind of sensor does not work - what a waste of money and time (sigh...) I am not unfamiliar with techies, computers, scanners, printers etc. (my warranty period has expired too).Folks looking for HP Photosmart 8050 - its a nice printer while it works, but don't go for it, its a trouble in slightly longer term.
