I have 2 Dell 1600 Laser Printers with the same problem. The paper does not feed from the tray. We can feed page by page thru the bypass but that's not ideal, as you can imagine. It appears that the arm that should lower the feed wheels is not lowering. Before I dig down too deep below the gears I was hoping to get some advice from anyone who has had the same problem.
Also, does anyone know who to contact to get a service manual for this printer. I've tried to call Dell but never get a person.
Thanks in advance,
