MF644Cdw Serial Number ?

[dws2006]

Just set up my new MF644Cdw. It is working fine and I want to register it.  The Product Registration website says the Serial # starts with 4 letters and ends with 5 numbers.  The Serial # on the unit does not match that format and the website will not accept it.  Anyone else run into this or have a solution?

Hey Darius im at Best Buy right now and it appears that all the mf642cdw they are selling are missing the phone jack ports. Are you saying that they are selling defective/damaged devices?
I was bringing mine back for exchange but it's not looking good:(

So the Mystery is now solved. The MF642cdw does not have fax capability but the MF644cdw does.
So this device that I purchased from Best Buy is a MF642cdw and comes with no fax ports even though the manual doesn't state it.

So the actual solution is that the device I purchased is a MF642cdw and is not fax capable hence it has no telephone jack.
