Question about Printers & Copiers
Sorry it's taken so long to get back to you on this. Since you get no dial tone with the hook function and you have verified you have a good phone line to the machine, sounds like you have a blown Network connection board. I do not have a service manual for this machine to give you part numbers out of. Do a google search for MFC5840 parts / service manual. The part you need is the board that the phone line plugs into.
