Summary: In common with some of the other reviewers, I purchased the 8660DN from Costco on a coupon deal. Additionally, I was aiming to replace a old Apple Laserwriter and an HP3210 Photosmart multifunction that I hve learned to hate. Finally, I just left the corporate world and needed a home office fax machine.
Summary: I bought this printer after reading some reviews posted here. But more importantly I've used Brother printers for some time now and had faith in this quality-oriented company. Rather than re-hash what's been said already I'll list my pros and cons: 1) This is a 'Energy Star' Vista ready printer. Have Vista on your computer? Just plug this in using your USB port and it's set to go. Haven't tried it on a network so can't comment. 2) Scanner operation is razor sharp.
Summary: This is my second Brother multi-function machine. The first one lasted forever, and we decided that it was time to upgrade. Also figured that getting this at Costco made it easy to return if we didn't like it. It periodically goes on special with a coupon, so that helped, too. This is my first network MFC. We had a Hawking Print Server attached to the old unit, and that worked okay. This one installed very quickly and easily.
Summary: I'm not new to the Brother MFC line, having owned the 8440D for almost 2 years before purchasing the 8660DN at Costco just a few days ago. I'm a business users, and the 8440D was a great device (except for the power consumption). I purchased the 8660DN to replace the 8440D because it has the built-in network card. I want to connect this device straight to the LAN without having to use a PC as a print server.
Summary: I'm surprised that one reviewer rated this machine so negatively. This is my fourth Brother MFC printer. My previous one mysteriously stopped working, but Costco gave me a full refund (after using it for two years), so I bought this one. It's a very good printer/scanner/fax machine and does everything I ask it to very reliably. Almost all of my previous printers were HPs, and I had pretty good luck with them but decided to give Brother a try a few years ago.
Summary: Prior to this I had an HP 3330, and it was good to me for over 7 years, but I decided to upgrade to a duplexing unit. I bought a Canon laser printer, and sent it back two days later to Office Depot--whoever designed that unit should be shot. Anyway... My wife was in Costco a couple of days later, and told me they had the Brother MFC 8660DN there, and since it's easy to return stuff to Costco, I told her to bring it on home. This unit is a dream. The footprint is small.
Summary: I was with HP for 15-20 years, needed MFP read all reviews here and decided that MFC-8860DN will be a good choice (other option was HP 3055). It has everything I need - copier, network print, scan, fax. Easy setup (I am in IT for 25+ years). Everything was almost perfect. The only complaint you need to keep in mind - IT EATS 1100 WATTS when starts printing - light could flash. It was OK, until I reached 1500 pages mark - it start printing small dots every ~3".
