I have now owned this printer/scanner/fax for a few months, and felt I had enough experience to finally provide a few thoughts on how I like it. I'll start first with the negatives, and then go to the positives.
I was having some trouble with the initial install of the printer. The directions asked me to use the USB cable to connect the first time around. Unfortunately, this did not work for me (for some reason, the computer was not detecting the printer during the install). After much troubleshooting, I finally got it to work by unplugging the USB and using the printer to detect the computer (rather than the other way around). I'm not sure why this worked, but it did.
Another issue I noticed dealt with the manual feeder in the front. It takes several tries before I can finally get the feeder to attach itself to the paper correctly without giving me a "paper jam" message (even after I follow its directions to use both hands to push it through the feeder). This happened each time I used the feeder, and eventually settled with sticking the paper in the bottom tray instead.
I was really disappointed to realize that this printer was not an automatic double-sided printer (which was the main reason why I opted to purchase it in the first place... the Best Buy associate told me it was). Apparently, it was only "double-sided" if I printed manually (in which case, refer to the aforementioned "manual feeder" problems above). By the time I realized this, it would have been too much hassle to re-package the heavy printer and bring it back to the store.
It would have been nice to have an ethernet connection option. I don't seem to have issues with the wireless connectivity (though I have read that others have); but I would have liked to have that option of a direct plug-in in case there were problems.
Probably my favorite feature of this device is the scanner. Compared with my old printer, this device scans material quickly and pretty easily. The software for this device is also pretty simple to use, so I don't have much trouble turning a document into a readable PDF, for example. If I am scanning paper documents, the feeder works really well (although, it did glitch once). If I am scanning books, I can get a copy of a chapter in a decent amount of time (it was definitely a lot faster than my inkjet scanner).
The second favorite feature is the copier. Although some copy jobs turn out a little darker than I'd like, I can get things to look OK after toggling with the touch screen to change the contrast, brightness, etc. When copying documents, the feeder on top, again works really well, and really fast.
Compared with my old inkjet, this printer is fantastic. The print quality is clean, crisp, and very clear. This, I believe is expected from a Brother device. As much as I dislike that this does not print double-sided, it is actually pretty simple to first print all the even numbered pages first, place it back in the bottom tray (face up & with bottom of page going in first), and then print the odd numbered pages. It is a little inconvenient, but at least it saves paper.
Overall, I am very happy with this device. There was a bit of a learning curve in the beginning (especially going from an inkjet to a laser), but I think it's worth it for the scanner/copier, and the higher-quality print jobs.
If you are still not sure of whether to get an inkjet or laser, I would say that it's important to consider some of the long-term costs. The print quality is much better with a laser printer, and the costs may not be as frequent when it comes to purchasing inkjet cartridges. But replacements for lasers, while not as frequent, can be much more costly (multiple toner cartridges, drum replacement, belt unit).
