Summary: A good machine with some frustrating quirks...
Comment: I love the fact that this faxes quickly and efficiently, and that it makes black and color copies, but takes up not much more space than a fax machine. I have just tested the color copy feature today for the first time, and I am pleased. It is fast and sharp. You can fax multiple pages without having to separate pages or have pages go through together as was the case with a fax machine that I owned for only a few weeks due to its poor feeding problem. I don't know about color faxes, so I'm not sure if I would ever use that feature. It's just a nice compact desktop way of having fax and copying options virtually at your fingertips. The unit is well-designed and appears to be well-built. I am using this fax/copier in a home office primarily for faxing out and making copies. I use a fax service from innoport.com for incoming faxes that are delivered to my email.
Since I wrote this, I have had an a vertical black line on all incoming faxes,and black and white and color copies. I am going to attempt to clean the scanner glass per the instructions of technical support. The other frustrating thing is that the bar that rolls the paper through the machine is very tight, so it can get jammed at times, but on the plus side, this machine feeds sheets of paper usually fairly well. A mixed bag - sorry I can't change my review to 3.5 stars. The color copy quality (aside from the vertical line) is very good and rivals that of an inkjet printer. The features for enlarging, reducing and changing tone and contrast are also very intuitive and helpful. It also is a very fast copier in black mode.
