I tried this question in the Hardware forum but no one answered so I am going to ask here.
I just purchased a 9 bay Wytron Duplicator tower with 9 pioneer 110D 16x dual layer burners. I have done approx 10 full tower burns without problems. My last burn it stalled out about 1gig short. I pushed the button for abort and nothing happened. Finally I tried ejecting the top tray and it ejected and the rest of the burn took place without any more problems. All the rest of the 8 burnt good copies.
So now the bottom tray ( please note, not the one I ejected manually during the burn ) will not stay closed. It keeps ejecting a empty tray.
thanks in advance.
