5.0 out of 5 stars Great Wireless Multi-Function!, April 23, 2008

By	B. Mills (Atlanta, GA) - See all my reviews (REAL NAME)

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.

5.0 out of 5 stars Excellent For Small Office - Great For Envelopes, October 10, 2008

By	Aaron SRQ (Sarasota, FL) - See all my reviews

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. I also took my own originals (a purchase order and envelope - both with various sizes of text and graphics) so I could compare apples to apples.

Most machines I tested had decent quality copying. There were differences, but all were acceptable for b&w general office work. Of course, copying was the only feature I could really test at the store. They all warmed up quickly and most were quiet enough. Here's what I found...

Brother MFC-8460 is too loud, big and imposing for my small office and took a little longer to warm up.

Canon 4270 has duplexing, which I was in the market for, but a funky half-tray for paper that was hard to load and looked like it could have problems down the road. Other than that, I liked it a lot (my second choice). Printed envelopes well and looked stylish.

Canon 4150 printed the envelope crooked and the coverage was too heavy and "grayed" the white envelope. I imagine this might be improved when changing settings from the print software to adjust for the thicker envelope paper.

HP1522NF printed the envelope uncrinkled, but it made a LOT of noise curling around the paper feed, which worried me. It also "grayed" the white envelope without being able to select a "thick paper" option.

HP M2727 did not print the envelope well at all.

Samsung SCX-4725fn has an easy manual feed, but toner on my graphics flaked off the envelope. It copied very quickly and quietly.

Brother MFC-7840w and MFC-7440n are pretty much the same except the they are different colors and the 7840 is wireless and better for networking. They both have backs that open so labels and envelopes can pass straight through and not wrinkle or curl at all.

I ended up with the Brother MFC-7840W from OfficeMax for $299.00. (It was $249 at Staples and Office Depot with a mail-in rebate - it's a long story why I couldn't get back to one of them and save the $50.) Not only did I like this machine best in my test, but I was happy with my old MFC-7420 and hope this updated version will treat me as well. The one thing I really wish the 7840 had that is does not, is duplex printing. If it had that, it would be the perfect machine.

I did a USB installation to Windows XP, which was simple and took about 45 minutes, but unfortunately the copier and scanner did not work. I called tech support and got through quickly. They couldn't help me, but quickly bumped me up to the next level of tech support. This next level was actually staffed with a real engineer who had the machine in the same room with him. After a few diagnostics he had me run, he determined that the logic board was defective and volunteered to send me a new one. I opted to return it to OfficeMax, who exchanged it with no problem.

I just plugged the new machine in and didn't reinstall the software. Now everything works perfectly and I'm very happy with this machine.

5.0 out of 5 stars Full-featured multifunction device, July 21, 2008

By	Travel & Tech (San Francisco Bay Area) - See all my reviews

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.
