excellent performer

This MFC-8860DN works extremely well. I was able to eliminate my (just died) fax machine plus an old laser printer/sheet scanner with this one machine. Scanner on the laser had just died too when this MFC came up on Craigslist second-hand, so it worked out well for my uses. Business, a thousand pages/month or so, faxing, scanning, copying. It'll do legal size copies, a plus if needed, and this has a flat-bed scanner, easier to use for books or such, PLUS an auto-feed sheet feed scanning option.
Yes, front single-sheet-feet door could be heavier, but this machine does what it is sold to do very well. Paper handling is top notch, Auto Document Feeder works great even 2-sided scanning. PaperPort OCR works well. Setup (I used an OSB cable, though parallel works too) is easy and simple, and you don't really need the manual more than the first few times you use it. I got mine used, a couple years old, summer 2008, and have run maybe 500 sheets through it, not one problem. Original owner had just started on second toner cartridge.
Paper curls at output, probably from fuser heat. Sometimes it bunches up and pages push out of the machine. You can help avoid that by raising a little flap in the output bin. Also, the paper path mangles envelopes, so you can't use them - don't buy this if you need printed envelopes.
Even though the paper path is far from straight, I've had no problems except with envelopes. I only run the AC in my office when it's really hot, so my office is often HUMID! Still the paper feeds fine and the printer prints fine. Brother did this pretty darn well.
In all, I'd say it's not for real heavy office use, but for a home office with moderate use it's a powerhouse.
