Excerpt: I purchased this product about a year ago. I started a small business and needed the capability to print and fax. I was skeptical at first because the cost was only $79.00 with a rebate. After the purchase I got everything hooked up and read the printer instructions there is so much you can do with this device. I print nice pictures from my digital camera, I am able to scan items and they look like the original-plus when I fax it doesn't tie up other operations.
Excerpt: I replaced my Brother MFC 7420 with this MFC-7840W 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 envelope, which works great. This printer is extremely quick and works well. I love the wireless feature so that I can print from anywhere in the house without plugging my computer in. It works well for double sided printing as well.
Summary: I purchased my printer in September of 2008, and it is still going strong. I have only hit a few glitches, but nothing horrible. For example, when I use the automatic document feeder sometimes the documents towards the back of the pile become crooked for the scanning process. This is only a few degrees and scans are legible and it works. I love that it can take a pile of papers and make a single PDF out of them.
Summary: I went through a few hours of frustration setting up the printer in wireless, and here's a tip for someone who might be in similar shoes: If your wifi security is WPA2 (WPA2-Personal in my case), on the printer select AES as the security type, not TKIP. The difference was never much an issue with my Windows laptop (MS can be sloppy and "beginner-friendly" that way), but strictly, WPA2 should be AES only (which I found out after the hours of battling with the printer...
Summary: Finding positive reviews on printers for more than home use has become a real challenge. I used to be an HP person but it was one bad review after another - especially for Mac users (which I am). So I went to Brother a while back - - I think it was the 5140dnl (?). It was a network ready model which I really needed. It was relatively fast but there were a lot of little things that would always be an issue.
Summary: I love this printer, but had issues with the toner running out so quickly. The replacement cartridge started giving me "Low Toner" messages after 800 pages. Then it died at 1,000 pages. I was mad that I had to spend another $50 on toner so quickly. But then I read the reviews for "Brother TN350" and found out how to trick the printer into giving me many more pages of output. Thanks C. MACPHAIL for the great advice!
Summary: We purchased on Amazon last October and now have 7 months experience of use with this Brother for our home and small business. It is our first Brother product. The printer output has been exceptionally good, scanner function is acceptable, and fax is fax. A key benefit of this model of the wireless connectivity. It has been impressive and very easy using included installation CD. We have had no issues printing wirelessly from any of the 5 computers in our home.
Summary: The Brother MFC-7840W is really a great printer and since it is built by Brother, I wasn't worried about the expectations. Design: The design of the printer is great, it is labeled as "compact" but it really isn't THAT small, though since it is an all-in-one I guess there is no way for it to become smaller. The black and grey color scheme really make it looks much more appealing and sitting in my office, it is not an eye sore.
Excerpt: I received this printer as a Christmas gift several years ago; even though I hadn't asked for one, it's definitely one of the most-used presents I've ever received! I absolutely love the wireless capacity. Since I am carrying my laptop all over the house keeping up with 2 kids, it's so helpful to be able to print a coupon or document from anywhere in the house. As a self-employed piano teacher, I print and copy all the time.
