All-in-One Functionality: Print, Copy, Scan, and Fax
The Brother MFC-9840CDW color laser all-in-one does it all, so you have to do less. It prints at laser-fast speeds of up to 21 pages per minute (ppm) in black or color. Printing is not only fast, but it looks great too. You get professional print quality at resolutions as high as 2400 x 600 dpi for stellar image-rich documents, presentations, signs, and business reports.

When you need copies, the MFC-9840CDW will deliver them at a brisk rate of up to 17 copies per minute (cpm) in black or color. Thanks to the 35-sheet automatic document feeder (ADF), you can take on multi-page faxing, copying or scanning jobs without having to feed paper manually. And the high-capacity dual paper trays hold up to 300 sheets, so you spend less time restocking paper. For even more paper capacity, the MFC-9840CDW can be equipped with an optional 500-sheet paper tray (sold separately) to bring the total paper capacity up to 800 sheets. Both the paper trays and auto document feeder can handle paper sizes up to 8.5 x 14 inches. The flat-bed document glass can be used to copy, scan or fax irregularly shaped or bound documents up to 8.5 x 14 inches.

The MFC-9840CDW scans documents with incredible accuracy at optical resolutions as high as 1200 x 2400 dpi and interpolated resolutions up to 19,200 dpi. You can scan your documents to a variety of formats, including JPEG, TIFF, and PDF. For even greater efficiency, the MFC-9840CDW also allows you to scan directly to email, OCR and more.

If all that weren't enough, Brother has equipped this all-in-one machine with a high speed 33.6K bps Super G3 fax modem for ultra-quick faxing. You no longer need to have four separate machines taking up valuable space in the office: the Brother MFC-9840CDW takes care of it all--printing, copying, scanning, and faxing.

Automatic Duplex Printing, Copying, Scanning and Faxing for Easy Two-Sided Documents
Produce two-sided documents quickly and easily, thanks to the MFC-9840CDW's duplex feature that automatically prints on both sides of the paper for professional-looking business documents. Automatic duplex also help to lower overall printing costs by reducing paper usage, mailing costs and filing space. Duplex fax and copying makes quick work of handling two-sided original documents.

Simple, Easy-to-Use Interface and Built-In Memory
The integrated and easy-to-read back-lit LCD display guides you through the operation of the MFC-9840CDW. Whether you need to fax, print, scan or copy, helpful display prompts make it easy to get started right out of the box. The 16 one-touch keys make it easier to access frequently used functions, and each key is relatively large and easy to read, so it's a breeze to use any of the MFC-9840CDW's many features.

The MFC-9840CDW features 64 MB of powerful built-in memory for better performance, including the ability to store up to 500 pages of faxes in the event of a power outage or running out of paper or toner. Up to 576 MB of additional memory can also be added (sold separately) for even greater memory capacity.

Built-in Wireless and Wired Networking, USB 2.0 and USB Direct Interfaces
The Brother MFC-9840CDW offers both wireless and wired networking capabilities, allowing multiple computers within a workgroup to share the machine easily. The MFC-9840CDW supports 802.11b/g wireless networking for wide compatibility, and also has a 10/100 Base-TX Ethernet port. No longer will you need multiple machines at each workstation. With the MFC-9840CDW you get one machine that will do it all for the entire group.

Other standard connectivity options include a Hi-Speed USB 2.0 interface to connect directly to your computer, plus a USB Direct Interface to print from and scan to a USB flash memory drive. It even supports easy, direct printing of images from any PictBridge-enabled digital camera without having to download to a computer first.

Place the MFC anywhere and print documents wirelessly.

I have waited many many years for the perfect all in one COLOR LASER....and this is it + more! I bought mine from a local store and have had it about a week. It comes in a huge box, but don't worry, this MFC is large but not too large compared to the other Brother mono laser all-in-ones (of which I have owned three over the years). The print quality is EXCELLENT and very fast for full color (21 pages per minute). My only initial concern was that it creased envelopes when printing on envelopes......but after consulting the manual there are fuser tension adjustment switches that solves that for perfect envelope printing (Settings, A, B and Envelope). I had compared many all-in-one color laser machines for many years (including recent ones from Xerox and HP). I was surprised that HP hadn't come out with a great, feature rich one yet. Brother beat HP to the punch and it is a knockout for sure. I am replacing a higher end Minolta color laser with flatbed scanner, a Brother MFC mono, and an HP mono workhorse with this ONE MFC-9840CDW!!! I am very very picky with print quality but this one is great! Bonus features are built-in duplex scanning, duplex printing, and wireless network capability! The replacement supply costs are also very reasonable and lower than most of the other color laser brands. Brother truly has a winner on its hand with the MFC-9840CDW!!! Thank you Brother....I LOVE IT!

My wife is an em elementary school teacher, and she gets limited numbers of copies for each term. She also has a great deal of worksheets and other papers that take up a lot of room and make finding a particular worksheet very hard. We came up with a plan: All of her documents would be scanned into a PDF with management software, and she would be able to make copies for her classroom when she ran out at work. We wanted a color laser printer with network scanning and duplexing and had looked at all the different solutions but were bummed to find that many of the scanners only supported printing from Apple computers and not scanning to them. Some had the options to scan to e-mail, but the documentation on these features were very limited.

After looking around at an HP model and a Canon model we decided to look at what Brother had to offer. We were pleased when we saw the specs and features on this model. The best feature was its Mac support which was very extensive. In fact, this was the only model in our search that had equal support for both Mac computers and Windows computers.

I found that the software on the Mac and its Windows counterparts were written fairly well. On the Macs that run 10.5 we had to get an updated TWAIN driver for scanner control, but that was the only small issue we had. You can walk up to the scanner, scan to the computer in the other room over WiFi or even save a scan to your Flash drive by plugging it directly into the front. It is very handy. The scan quality was on par with what I expected. I wouldn't use it for high-end photo scanning, but an occasional family picture scan here or there, especially for web distribution will be just fine with it.

The print quality was also very nice.

I just got this machine to replace two others a month ago in my home office - an HP inkjet all-in-one 6310xi, and a Brother laser printer HL-1870n.

This new unit is superior in just about every way.

The print quality is much higher than on the HP. In B&W it is similar to the old brother laser.

The print speed is out of this world, especially for color. The inkjet could take minutes per page for letter-size photo prints. This one doesn't seem to take any longer than for other prints, amazingly ! This is no doubt thanks to its 128 MB of memory. I was thinking about upgrading the RAM, but there just isn't any need to do that at all !

Copies are also spectacular, just as fast as any photocopier. The HP all-in-one could take several minutes per page in the highest quality in color, and typically at least a minute even for high-quality black & white. And of course the quality is much better.

Scanning speed is also great. It is really measured in pages per minute, not minutes per page.

The ADF duplex scanning is invaluable.

The bundled software (Paperport) is also very reliable and far superior to the bloated crap that came with the HP.

Despite its size, this unit actually saves office space compared to having two separate inkjet color and black & white laser units.

Photo prints are very good. I have noticed some yellowing compared to the inkjet prints. But I am confident it's possible to adjust this in software and make the photo prints just as good as the inkjet. I just haven't had time to fiddle with it yet.

The unit is not perfect, but nearly so. There are a couple things that I wish were improved :

- The ADF is limited to A4/letter size.

Verified Purchase
So many good things were already said. I just want to add a few things I learned while using the product over the last few months:

- Only one job can happen at the same time. While you print you cannot scan or fax no matter how much memory you have.

- Reviews often state that the printer has only medium color printing quality. The printer is great but the PCL driver is not. Use the Postscript driver instead, which is a little bit slower, and you get results, which I would say are similar to HP. The difference is amazing.

- Scanning works perfectly. I use it to do editing on print-outs and then scan it in, and send it back to the publisher. I also use it to archive hardcopy documents. It is very fast with 400 DPI b/w scanning. The feeder pulls the paper sometimes not totally straight.

- You can use standard notebook memory to increase memory. It eats old 100 Mhz SO-DIMM in up to 512MB size.

- It takes a while to warm-up. Both when printing and scanning. It makes the light flicker when it warms up. It works well on a shared 15A circuit so.

- I love the iFAX feature. I can send a fax, have the printer convert it to a TIFF, and send it directly out via a SMTP server without needing a extra computer. I use for sending stuff to an Oracle ERP archiving system. (It can also convert to PDF.)

- It also can scan and send a document to FTP or via the Control Center to a PC or save to local USB flash. You can remote control the functions of the printer via pre-sets on the Control Center app.

- It faxes and copies in b/w and color. Quality of copies is good and very fast when you use the document feeder. It appears to be faster then the small copy machines at my local copy shop.
