Have a machine jamming every print from every tray except the bypass. The paper never makes it around the vertical path, stops just prior to entering. I checked all the guides for obstructions and found none, can manually pass a page through. I cannot hear the vert feed motors in test mode, even with the back cover off and controller box opened. Thinking of the cassette feed PCB as that what supplies the drive to them, but would be great if someone has seen this before. The code never changes, started suddenly, and is consytant from all trays, except the manual bypass which works fine.
Thanks!
