Thank you so much for this. I'm not mechanical at all, but I turned the printer on its
side, found the wheels and turned the rubber rings inside out.
Now I can use the tray to feed. I now get the error light coming on each time after printing, but it still prints and works well. You just have to hit the blue light (continue) and it prints. I see that the error light refers to a secondary error, have tried loosening or tightening the paper in the tray. For now, this error light is not doing any damage, so I'm not worrying about it. Thank you again. You are a dream.
