The Brother MFC-9840CDW is a multifunction colour laser printer, copier, scanner and fax machine, with wired and wireless networking capabilities. It doesn't come cheap, but if you're looking for a versatile machine that does its job well, the MFC-9840CDW is a worthwhile investment. It can be a little tricky to use - especially when you're setting up wireless printing - but you end up with high-quality output that's produced quickly.
Setting up the Brother MFC-9840CDW was a breeze. After powering up the machine and installing the toner cartridges, you have three connection options: ethernet, USB 2.0, or 802.11b/g wireless. Connecting via USB is as simple as it sounds. The trickiest connection setup was the wireless, which required setting up IP printing. The user manual, however, does a good job of directing you through this process.
The Brother MFC-9840CDW's control panel is well designed and clearly labelled. Three large buttons allow you to choose between the fax, scan and copy functions. The control panel consists of rubber buttons that are pleasant to use, and a bright, backlit LCD clearly displays the settings you can choose from.
The Brother MFC-9840CDW includes a convenient automatic document feeder to make copying easy. A nice bonus is the ability to copy double-sided documents by pressing the Duplex button.
Disappointingly, the scanner software included with the Brother MFC-9840CDW doesn't offer very flexible scanning options. It is, however, easy to use and straightforward.
Brother's MFC-9840CDW outputted very good results overall, and text quality looked clean and professional. Colours were a little on the light side, but images looked pleasing overall. The scanner's output looked slightly dark compared to our control image, but the device captured fine details and the overall image was clear and realistic.
The Brother MFC-9840CDW's print speeds were impressive. It took just under 40 seconds to print a 10-page Word document, and 15 seconds to print a one-page Word document. Colour scanning was on the slower side: it took 1 minute and 11 seconds to scan an 8x10in photo at 600 dots per inch (dpi).
