I had the print head changed after 9 months, 12 months later same problem, paid £400 for this printer. I will now scrap it, waste of time.

Returned it to Brother just after the warranty terminated for new print head. They did renew it for free though but a year down the line, guess what, it needs another print head and at $99 for a replacement I'm afraid it's going in the bin. Never again.

I like this Brother MFC 4820c 'all in one' machine, just wish it was more reliable. Had 'error code 41' which needs an engineer to come and change the print head - and mine has gone twice in a few months!!
Used loads of ink, and seems to need cleaning very often which uses ink.
Will only take normal thin paper - I can't use my slightly thicker letter heads in this machine, when it will work fine in my HP Laserjet...
Lots of the features are hidden deep in the menu system which can be fiddly to find, but to be fair most similar machines are the same, and some of the main functions have dedicated buttons on the front.
Apart from that it does everything else you will need, and if you find a cheap one (still under guarantee) then I would think about buying it. However, I can't help but think there are better made and more reliable machines out there.

I wanted an all-in-one, and this Brother MFC 4820c seemed to fit the bill. I was surprised at how life-like the scans are, however, the print quality is poor and slow. Works fine as a fax and answering machine.

Setup using the keypad and screen is cumbersome.

I paid 700 dollars for this printer. Everyone said "go HP, they're way better". I looked at this printer (Brother MFC 4820C) and thought "for 700 dollars it better be good". HA! Boy did they see me coming! Unless they have got a lot better with their new printers... I say bring on the HP...
