There is no way I am going back to an ink printer, but I used to have to if I wanted color print. Now I don't have to. Yeah!

Had this color laser printer for over a year and before that I had a B&W version of that printer from Brother. I find absolutely no reason why I would want to switch to another printer maker. Their product has been extremely reliable for home use. I would not be very surprised if they did well for small office use too, and if I had a larger business doing lots of color printing, I would certainly buy one to see how it compares to more expensive ones (i.e. those you have to have a maintenance contract for). I bet if it broke you could get a new one for less than the maintenance contract price and that in the long run you would save money. If you are so desperate to have quick maintenance, buy an extra one and keep it in a store room. At about $300, you can pay it from petty cash.

This printer was purchased for home office. I was concerned about shelling out this much cash (although the best deal by far was though Amazon!) for a printer as I already had a multifunction. My issue was that I have 4 computers with 3 different operating systems and nothing has worked right (or at all) since we were forced to upgrade to Vista on 2 machines. After reading the reviews and contacting Brother directly, I purchased the printer and so far, I am very happy with it.

Pluses
-Super easy to install on the network
-Cost effective laser printing
-Works with all my operating systems
-Can manipulate scan type needed directly at the PC requesting it (ex. PDF, jpeg, tiff, etc.)
-Inexpensive color printing

Minuses
-Its heavy and big. This is not something to sit on your desk and you probably will need 2 people to move it.
-Its not photo quality printing...but it never claimed to be. Its still pretty darn good.

I am a real estate agent and sorta live or die with computer and printer.  This is the 3rd MX922 in 6 years I have installed in our office.  This printer does all it says it will do and then some.  There would have been 5 stars except that this printer sometimes creates delays (usually not too long) to perform its magic.  Great printing in B&W and color, affordable supplies, good FAX machine.  Great deal for the price.

I purchased this printer to replace an old HP printer which I was very happy with, but the ink is no longer available and there's no Windows 7 driver to do automatic double-sided printing. Also I liked the idea of wireless and of having the copy and scan functions as well as printing. Fax would have been nice but since I don't have a landline phone it probably wouldn't work very well anyway.

Setup went very smoothly, and I used WPS to connect it to my router and never had to use the USB connection at all. I only installed the drivers, the scan utility, the on-screen manual, My Printer, and the network and scanner selection tools. The install could have been a little more informative and told me the printer had successfully connected to my router, but it's a minor point.

The text and images I've printed look great, the test image I scanned looked great, and the test copy I made looked similarly great both in color and black and white. So far I've used only plain paper so I can't speak to quality of images printed on photo paper. Automatic double-sided printing worked well.

My only real complaint is that the paper trays are flimsy - I have cats, and when I'm not using the printer I leave the paper output tray closed and the paper stop thingie folded in so they won't step on them and possibly break them. Speaking of, the paper stop thing is kind of clumsy - it rotates way out and can't be shortened. But it really isn't needed unless you're printing multiple sheets so I leave it folded in.

It may sound silly to focus on appearance but this printer looks really beautiful - glossy black and with the paper trays both closed it becomes a compact and classy-looking box. It's got a pretty small footprint for an all-in-one and that's a big plus in my limited space.

Edit 12/6/2012:
I've removed one star from my rating because the printer has major paperfeed problems. Every time I use it I have to manually push the paper in or the printer won't grab it. I've tried cleaning it but that doesn't help.

Pros: Setup took under and hour from the time I cracked open the box as a wireless lan on 2 PC's, one running dual boot Windows 7 and Vista Ultimate and the other Vista Home Premium. You do want to pay attention to the somewhat confusing work flow chart in the manual that tends to jump all over the place, but if you do so it should install with no glitches. The printer prints very rapidly in B&W and does a beautiful job making professional looking color prints with excellent detail. My wife loves the fact she can make copies without involving a computer and that my PC doesn't have to be on for her to make prints from her laptop. The MP620 is a reasonably quiet machine and seems to be well designed overall. I also like the dual trays as I can leave photo paper in the rear tray and still print text from the bottom tray.
Cons: The paper trays are not quite as sturdy as I would have liked and as was mentioned in a few other reviews, but if one is careful they should do the job. I was disappointed that the built in card reader doesn't seem to offer to open any of my photo programs as my now defunct Epson printer did, but instead wants to set itself as another drive on my computer. You can, of course copy from this drive, but since it's wireless lan, it's a bit slow. Since I have other card readers, I still gave it 5 Stars, as I got it more for printing than anything else.
Amazon Cons: I too originally ordered from Amazon,as another reader did  only to check my order email invoice later that day and see it also showed a delivery delay of over a month! As my current printer was quite dead I too canceled my Amazon order, ordered from another source and received it within 3 business days. If Amazon does indeed either have this printer in stock or not, they need to straighten out their system. I ended up buying from another source because of it!

Good printer, scanner, and copier.  Fax loses WiFi signal so frequently, it is hard to use.  No other WiFi device in our office has this problem, so it has to be this machine.  Otherwise, good product.

The only thing this behemoth is missing is a fax.  It is so luxurious to have a home printer that prints on both sides without any outside help.  The Mac interface is lame compared to what is provided for windows but, in my experience, that's always the case.  The copy and scan functions are great and print quality is excellent.  So far, the ink usage has been much better than with an HP -- about the same as my old Epson but without ink splashing all over the inside like the Epson was so fond of doing.  Unlike an HP, the Canon seems to have no problem grabbing a piece of paper and printing on it without jamming. I've had the Canon for 2 months and so far, so good.

Here's an update. It's 8 years later and I still use this printer all the time. However, after doing a Quicken report, I have to admit I have spent probably $3000 on inks in 8 years!! Is that crazy or what?? That's like $375 a year. Wow!! I am stunned.

I ordered this printer with scanning in mind. I am in the process of digitizing pretty much everything. So far, I've scanned around 3,000 family photos and documents from my mother and grandmother. In all that scanning (easily 50 hours worth), I've only had one issue: I noticed one-pixel-wide vertical lines in some of the photos. I caught these lines during the scanning and turned the printer off and then on again. I rescanned the affected photos and the problem was gone. Since scanning is my main use for this printer so far, I give it an A+.

Other essential functions for me:
Duplex scanning through the ADF: A+
Duplex printing: B+
General printing: C

The printing has been the worst part of this printer and the reason I only gave it 4 stars. It is SLOW. I've owned and used 5 printers in the last 12 years and this one is by far the slowest to print. I gave duplex printing a B+ because having the function is essential for me, but of course it's even slower than regular printing. I had to print about 30 documents to prepare for a job interview a month or so ago, some duplex and some not, some single page and the longest about 5 pages, and it took over an hour to finish the job. I don't usually print a ton, so this has only happened to me this one time, but this printer probably won't work for you if you print a lot.

I've also had a couple of paper feed issues where the printer would suck up 2-4 sheets at once instead one and ruin the print job. I since moved the printer to a different surface and haven't had the issue again, but it seems pretty sensitive to how smooth and stable the surface you put it on is. Not a big deal, but be aware.

Overall, this printer has been a workhorse and I'm very pleased with its performance, especially the scanning. The slow printing isn't ideal, but with the amount I print, I can get over it, especially with the awesome scanning.

Overall I am very pleased with this all in one.  The two sided duplex scanning and printing features are amazing.  I also like the rear paper slot for printing two sided greeting cards where the paper has to be turned over.

My only real complaint is the fax feature.  I have to use a PBX style system that requires a 9 the phone number and then a PIN.  Getting the printer to accept this was tricky as it was not in the instructions nor was tech support able to help.  I ended up figuring it out on my own using the pause function.  It's a bit complicated to enter all those digits and pauses but I've made it work.  I wish it had the old style hook dialing that some HP printers had.

The printer I had previous to this was a&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/HP-OfficeJet-4650-All-in-One-Color-Photo-Printer-with-Wireless-Mobile-Printing-Instant-Ink-ready-F1J03A/dp/B013SKI4X8/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">HP OfficeJet 4650 All-in-One Color Photo Printer with Wireless & Mobile Printing, Instant Ink ready.

Packed with all sorts of high end office printer features:  Autofeed scanner great.  Print quality great.  the ability to hold standard paper and photo paper in self contained and "hidden" trays is great.  Wifi printing is great from multiple devices including windows 7 computer and android phone.  I haven't tried out all the features yet, but I like what I have tried.

A couple of negatives to consider:
Needs super special paper every time you want to print a test page for alignment etc... and it only comes with two of these.
It takes FOREVER to print the first page, as in you can say "print", finish your coffee, go wash the cup out, answer a couple txt messages and emails and then see that it has STARTED to print the first page.
The drivers and software a pretty bloated, ans not so intuitive.  I guess this is a standard for at home all in ones, but this cannon's software is a memory hog, is defaulted to autostart and will take over a good part of your desktop when it does.  I recommend setting preferences for it not to autostart so you only have to deal with it when you want to scan a pdf.

An outstanding piece of equipment! This has replaced a 20 year old B&W copier, thermal fax machine and several college-quality ink jet color printers. Only two minor caveats: 1- It is, as others have mentioned, huge! While I had no trouble with placing it in our office as I did the measuring after reading earlier reviews, I was still surprised at how big it is. 2- My experience with Brother printers has been that setting up the Wi-Fi using the wizard was easy. I did have difficulty in getting it to accept the password for my Wi-Fi. Trick-I had to reboot my network to get it to work.

Otherwise set-up and performance have been very good. The Wi-Fi connections are surprisingly fast, using laser color is so much better than ink jets which are slow, expensive, and dry up quickly when not in use. I don't use fax too much anymore, but this sets up quickly and seems to work fine over FiOS broadband-shared Ooma voice line for small runs.

Bottomline: I'm impressed. I started off with just wanting to get rid of my old equipment and consolidate space, and I find I'm getting additional and valuable productive work done to boot! I have used the two-sided auto scanner saving to to the USB drive on front of the machine for large documents saving me much time. We have an Apple office so it's great to be able to send docs from our mobile devices to be printed out no matter where we are. Also we are using color printing more as high capacity color toner cartridges are not expensive (especially compared to ink jet), which is great for graphs and financial reports. It even does a good-enough job of printing photos on basic copy paper. The double-sided automatic scanning/copying seems to be unique for this type of device and does add a bit to the cost, but is definitely worth it. And I found it was reasonably priced compared to other devices I researched.

I'm a fan and would highly recommend this device for all the reasons above.

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. I was able to discuss the Brother, HP, Xerox, and Canon solutions with their respective factory reps at the 2008 Macworld exhibition in SF back in January, as well as demo most of the applicable products. So, the Brother unit won the battle of live demos and Costco pricing.

Here is how the 8660DN dealt with these missions:
1. Faxing - It's full featured and just a great performer. I have to send faxes every week due to health insurance and investment order processing. It's easy, fast and has all the memory a home office could ever use.

2. Printing - My home network has four computers attached running Mac OSX (10.4 and 10.5) in addition to a laptop running Windows XP. I have WiFi and hardwired connections. The MFC does a great job of printing in both single sided and duplex mode from all our computers.
***** ONE ISSUE: Do NOT plug the MFC power cord into the same circuit as the network router or any other network hub. When the MFC awakes from sleep, the startup power surge is sufficient to glitch the hub and lose the network address assignment necessitating a re-cycle of the MFC power switch to reconnect to the network. *****

NOTE: The above issue was diagnosed by Brother's excellent (in my opinion) customer support. I moved the power around, and now it's fine.

3. Scanning: Both network and USB connected scanning work well and produce moderate to good quality scans. It's not a replacement for a dedicated scanner, but it's fine for home office work. Also, the ADF works really well.

4. Copying. It's just great and is a much used features. The enlarge and reduce functions work well with presets for letter, legal, etc.

Conclusion: This is a great unit

The printer, scanner and copier work very well - easy to use, good quality print, doesn't use too much ink.  I haven't been able to figure out how to use the fax, however.

Great printer!  This is my third Brother Multi Function Printer.  All have been very dependable.  The B&W laser prints are the lowest cost per page and trouble free operation.  {I have had problems with ink jet printer ink drying and plugging up when not used frequently.}  The ability to scan, fax, and copy makes it a great home office machine. The ability to print via WiFi or Bluetooth is a great addition, and it allows me to print directly from my phone.  I also use the PC-Fax feature to send out fax blasts, but that software needs work to make it more user friendly.  I use B&W for its low cost per page, but there is a similar Brother color laser printer that produces lower cost color prints and copies.

The MF4150 is awesome.  Prints very fast.  Text is crisp and clear.  Graphics are pretty good.  The ADF is nice for scanning a bunch of papers to PDF for reducing paper clutter.  Duplexing is great.  And the price was excellent for the feature set.

If I had to change anything, it'd be to add a duplexing ADF so that it could easily scan 2-sided docs, and ethernet connectivity would be nice as well.  But, Ethernet can be added by buying the MF4690 (albeit for about another $100).

Very happy with this printer / scanner / fax! 1st: THE INK LASTS LONGER, AND IF YOU RUN OUT OF COLOR INK YOU CAN STILL PRINT IN BLACK!!!! 2nd: A PAPER JAM IS EXTREMELY RARE AND HAS SO FAR BEEN MY FAULT (sloppy feeding of paper.) I've had it about a year with no problems. After using Epson and Hp, I will never go back to them (see all-caps for reasons.)
