I had a flyer which I printed. I loaded the paper try with card stock and it indicated it was out of paper. When I couldn't correct it I changed back to regular paper however it continues to state it is out of paper. I have followed the all of the help topics but there is nothing too do.
Try removing and readding the card stock to the paper tray. Perhaps the paper sensor on that tray is malfunctioning and needs to be wiggled loose or reset. If the tray cannot detect any kind of paper then consider servicing or replacing the paper tray which would include the paper sensors too.
