Summary: As with the other reviews...this thing uses ink like it's going out of style. It cleans itself like 30 times a day. What finally happened is the magenta stopped printing. Apparently it happens to EVERYONE who has this machine. Do yourself and favor and buy a different brand. Brother DOES NOT care about the consumer.
Summary: Do not waste your money on this printer! We had an Error 41 while it was still under warranty and had to send it in (which means we were without a printer/copier/fax for about a week and a half). After it got "fixed", we got another Error 41 (Imagine that!!) right after our warranty expired! Save your money.
Summary: when every single person posts about this error 41 and yet the company continues to sell defective products, well, that shows you what they think of their customers. never never never again brother.
Summary: Save your money and look elsewhere. Without fail, this machine will give you the "Machine Error 41, Call Brother Service" in 14 months or less after you buy it. That will mean replacing the printer head or throwing it in the trash if it is out of warranty. It has now happened to me twice with this machine.
Summary: When I realized this machine uses alot of ink for its periodic print head cleaning, I got a different brand of printer to use and I set this one aside, but left it plugged in. Starting with brand new ink cartridges, over about 6 months, and NO printing by me, it would use up all the ink in the cartridges - I guess through the print head cleaning cycles.
Summary: I wish I had never bought this machine. It is mainly used for printing but I thought it would be great to have a fax / scanner as well. Firstly, the clean cycle starts up at odd times, usually in the middle of the night (in a small 2 bedroom house that is not nice!) and secondly it uses a huge amount of ink for the number of print jobs I do (maybe there are mice using it in the middle of the night?
Summary: MFC 3820 Slightly over 1 year old, extremely light use. It stopped functioning and displays "Machine Error 41, Call Brother Service". I Unplugged unit, waited, plugged it back in. Same error message. Google searched "Brother MFC Machine Error 41" and discovered thousands of people have had this problem more than once.
