we have a WorkCentre 6605 that until a few days ago printed faxes from tray 1 as set by the technician when we bought it. Now it prints faxes from tray 2 which we use only for prints from computers. We could not reach the technician and we don't remember how to set it the right way. We have already checked knowledge base and user guide but we cannot find how to set the machine to print faxes from a specific tray. Could you help me please?
