I spent about a week researching for just the right multi-function printer for my needs. I own a small business with about 30 employees so I needed more than an inkjet but didn't require a 'corporate' $1000+ version either. I needed fax, scan, copy, and print capability with laser printing and built-in wireless capability. Suprisingly, there are not that many printers on the market that can give you all of these in one package. Originally I was going to purchase the Brother's MFC-8870 for around $500 which all the reviews on the internet recommend, but I found this while browsing around and realized that it had just come out a few weeks ago. Although there were no reviews out yet for this new printer, it was considerably less expensive than the 8870 and the only thing I seemed to be losing was auto-duplexing so I made the purchase. It took about 15 minutes total for me to set up an ad-hoc wireless printer setup and everything works great. The scans are nice, the printing is very crisp and clear even in very small fonts. The only thing I haven't tried yet is the fax which I won't be using much. I really can't say anything bad about this product. Sure it would be nice to have a legal-size flatbed, auto-duplex, and 64mb memory (instead of the default 32mb) but for the money this can't be beat. Overall, this seems to be a really great product at a great price. I highly recommend this if you need a 4-in-1 with wireless capability. Definitely the best on the market for this niche.

I replaced my Brother MFC 7420 with this MFC-7840 and am very happy with the upgrade. It does everything I need and is small and quiet in my small office. It has a straight paper passthrough for envelopes, which works great. Read below for a comparison to other similar models.

I've had a Brother MFC-7240 for 2 or 3 years when the fuser went out last week. A new fuser is $150 + $75-100 to install, so needless to say, I decided to buy a new all-in-one machine. My Konica Minolta 2430DL color laser printer also conked out at the same time and I investigated replacing both with a color laser AIO. After not having much luck finding one of those that could easily print envelopes, I decided to stick with two different machines. In retrospect, I'm glad I did - it's good to have two printers around to back each other up just in case. (If you've got really light duty needs, consider the Samsung CLX-3160FN, which I came across in during this first shop. It's dirt cheap for a color laser AOI. Very small and very quiet, but not solid enough for a small office load.)

After reading up on monochrome laser AOIs for much too long, I narrowed my choices down to about a dozen in the $200-$500 range. I refuse to buy something I can't see and play around with first, so I went shopping at local stores to see the models I chose in action. I went to Staples, Office Depot and OfficeMax. Tried for Circuit City and Best Buy also, but believe it or not, they don't carry ANY monochrome laser AIO machines in their stores - only on-line. A manual feed and envelope printing are a must for my use, and reviews I read were conflicting, so I took a big stack of envelopes to test the machines out myself.

This is a very nice printer and I agree with the other reviewers positive feedback. But there is one problem I have found for those who print forms and envelopes via the manual feeder. When the printer is in sleep mode and you put a piece of paper in the manual feeder the printer wakes up and does a small grab of the paper. Unfortunately this small grab puts the paper off center so if you are printing on form paper it is a real nuisance. A solution may be to wake it up first by printing something else, then put in your form paper and print before it goes to sleep again, but again not the best solution. Also the lack of ability to put multiple envelopes in the manual feeder I find is a weakness. All my older LaserJets could at least handle 5-6 envelopes in the manual feeder. After reading many reviews though I find that trying to find a MFP that can handle envelopes is a major problem in itself and this printer is no different. I also noticed the toner that came with the printer did not last for nearly as long as advertised, it started showing toner low very very soon!

I was looking for a laser multifunction device with network capability that I could use to print from my laptop anywhere in the house. A lot of reviews seemed to point to the Brother MFCs as the best overall brand for laser monochrome devices. The only problem was that there were a LOT of different models to choose from - just going to the Brother website to do some comparison shopping made my head spin.

The MFC-7840W is a recently introduced model which has seemed to get good reviews across the board. A major plus is that it has both wireless and wired network capabilities. I took the plunge and purchased this model. Since I already had a wireless router to plug it into, I didn't need to use the wireless capabilities, but it seemed to be a nice option for future flexibility. The Ethernet connection was easy to set up and worked the first time I tried printing from my laptop.

I've been very pleased with the quality and feature set of the MFC-7840W. Not only does it print high quality output, but it has clearly-labeled buttons for scan, fax, and copy, which makes it a breeze to use any of these functions. Plus, the device is relatively light and doesn't have a very large footprint, so it fits easily on top of a small file cabinet. High marks overall.
