Summary: minimal
Comment: Brother 7820N:
1. Cannot reliably print envelopes, including and especially #10. If that's important to you, find another machine.
2. Scan for fax very slow. VERY slow. Interminable.
3. Software minimal, very poorly designed. Fax and scan management thin, missing functions and management options.
4. Support (help; manuals; online) incomplete, inaccurate.
5. Will not automatically re-set after paper jam clear. (Have to power cycle.)
Everything about the machine says "absolute minimum"--fit, function, design, engineering, materials, assembly, software (incl driver).
A reasonable guess: Brother put the machine out there to hit a price point. Sold a bundle of them on the strength of early reviews.

Summary: DO NOT BOTHER
Comment: I assume other printers/copiers must do their jobs better than this one. The quality of the output is fine but I have constantly had to clean the drum (done easily, admittedly). The two worst features are its inability to print envelopes--at least five creases per envelope on every try--and the print/copy output comes out very curled and winds up on the floor. This printer appears unable to copy/print more than ten pages without pushing it into a messy pile or all the way onto the floor. And did I mention the high degree of curling of the output (I did, but I will do it again). As a small business I will not buy a Brother printer-assuming they all share these faults (admittedly could be wrong). I will search another company's product line.

Summary: Oh, Brother !!!!! You are fast and cheap.
Comment: The printer is fast in all respects: printing, warm-up, copying, scanning and faxing. The automatic paper feed is outstanding. The output (printing and copying) is clear and excellent. The only negatives are that the envelopes get creased pretty badly when being printed and the paper seems to curl a lot. The creased envelopes, I think, has to do with the tightness of the paper feed. The creasing occurs only in the lower right quandrant of the printed envelope. The curled paper probably has to with heat within the unit (I never turn the printer off) although it goes into a "sleep mode" when unused.
I still recommend the printer because I generate a lot of paper output and create few envelopes. I am investigating a better grade of paper which may solve the curled paper issue. This is a fantastic value and it a good-looking device.

Summary: Nice small office printer
Comment: I have always been happy with Brother printers, and this one is no exception. It prints fast and clear, the functions are plentiful and it doesn't take up all that much desk space. One thing I have noticed is that the paper gets kind of curled after if comes out of the machine if you print a bunch of copies. And it's not very convenient to get the printed pages out of the middle of the machine. But overall, a very nice machine and one that I would recommend.

Summary: Super fast little guy
Comment: We have been using this printer for a little over a month now at work where we print an average of about 100 pages a day and this little guy chugs through it like it was nothing. The best part of it all is the speed. It is quick to warm up and prints 30ppm, which is a billion times faster than our previous Brother printer (or so it seems). The print quality is excellent but so are most laser printers so that's not really a stand-out. As mentioned by everyone else here, the envelopes do get a little crinkled when they are printed through the printer but that beats our last brother printer that seemed to jam more often than not when printing envelopes. I have yet to have an envelope jam. A trade off (crinkled envelope to jammed envelope) we are willing to take any day. To print an enveiope you have to open a little door in the front of the printer to access the feed for it. Not a big deal but I thought I would mention it. So, why four stars? Well, the crinkled envelope issue mainly and also the plastic quality used to build the machine seems a little cheap (at least compared to our last Brother printer). Definitely not a big deal but warrants the four stars.
