Easy to use
Bought this for my 87 year old Mom, and it was very easy for her to use it. She loves the one button speed dial to fax. She got confused where to put in a sheet to fax, but now she is a champ at it.

It would not send faxes and I returned the machine according to instructions from HP. They sent me a new 2140 that seems to work ok.

Disappointment in quality of 640 fax
I find it odd that when this 640 fax machine is on the way to be returned for poor service and lack of quality that you ask for a review on it. . This equipment is much poorer grade than all the many HP products I have purchsesd for the past 25-30 years or so.
