Hello Luc,

I just had the same problem on mine. With the help of William W.
Hopper Jr.,(thanks William) I was able to fix this problem. It is a
purely mechanical one caused by a little relay located in the
(optional) lower paper tray.

Let me know if you need more details and I'll send the to follow
procedure to you.
