HP Laser Jet Pro 300 color. When I try to print or make a copy from the flatbed scanner, the gears keep turning but no paper comes out. The gears continue without end until I finally cancel the job. (I've let it go for over 5 minutes to see if I could get an error message, but the screen just says "Printing document".) I've tried printing using the paper tray and the manual paper tray. I've tried small print jobs, large print jobs, I've tried printing a copy by using the flatbed scanner. I've replaced the rollers, cleaned the cartridges, checked for jams, restarted the printer, unplugged the printer, restored to default settings. Everything seems to work as normal, it seems to be having an issue with picking up the paper. ON OCCASION, the first page of the job will come out. But for the rest of the pages, the gears just keep going and going and going.
