Bought a Brother 4-in-1 printer to replace an older one we had. Ended up with their MFC-L6700DW model. Once we has set it up, it immediately started tearing documents we put in the feeder (including important legal documents). Tried to get help from their "Live Assistance" help screen, the person just fed me a lot of bulls**t about "try this, try that." It appears to be a bad design, just one feed roller vs. three on our old Brother machine. Unless they replace this with one that actually works as advertised, that was the last Brother product we ever buy!
