Summary: Slick and easy
Comment: Very easy to install (and use). Replaced a unit, which after many years of service said 'enough already' and quit. Print, speed, and ease of use superior in every aspect.

Summary: Great for occasional use!
Comment: The HP 640 inkjet Fax Machine is a nice compact, easy to use product. It is great for occasional use if you have a business and want to use it once a week or so. Also the price is right!
I use it in my business but only occasionally, three or 4 times a month tops and this is exactly what it's good for.
What it is not? It is not a high quality, last a real long time, heavy duty fax machine. So if that's what you need this isn't your product. Additionally, I wouldn't recommend this to be used as a telephone, the receiver is very flimsy, weighs maybe an ounce or two and the sound quality is poor.
That said, I recommend the fax portion of this product highly for occasional use and light duty.

Summary: Great Fax Machine!
Comment: This is the best fax machine we have had. I like the fact that it uses inkjet instead of film.

Summary: Great Little Machine
Comment: I bought this fax as a replacement for an older film type fax. Good decision! It is quite compact, makes good copies, and is a trouble free fax machine that works well in conjunction with an answering machine.

Summary: Distinctive ring defective
Comment: This fax machine is supposed to recognize my distinctive ring. It does not. It randomly picks up my phone calls and screams in their ear. I followed the directons to set it up ( by the way the distinctive ring option is uder the Basic fax menu not the advanced fax menu, as it states in the directions.) I've talked to two different tech guys in India for four hours with no luck. We cleared the machine and started over but no luck. They finally gave up on me and I'm giving up on HP. I had to order another fax from another maker and really don't know what to do with yours.
