C3765DNF Won't scan? Copy Yes.

I have a problem with my C3765DNF

I can't feed to scan. Network and SMTP settings are all good and correct.

It just won't feed and scan the paper... If I use for the Copy feature it works. But if too scan then it fails...

Keeps telling me there is an error in the network.

Anyone else has the problem?

Also where can I get a motherboard for the priner - maybe its something with the Motherboard....
