Rated 5 out of 5 by from Great value printer I bought this to replace my MFC6490CW which I have had since 2009 and has functioned without fault. This has similar funcitonality and cost half the price, plus I got cashback from Brother! Great upgrade.
Date published: 2023-09-07
Rated 4 out of 5 by from Fast and good quality print. Basic scanning This is used mainly as a printer. The print is fast and the duplex action is reliable. Upfront cost for printer ink is very high indeed but we are hoping that the consumption works out to be reasonably economic. We do not use scanning much. The scan of documents is satisfactory and reasonably quick. Connecting to the PCs on the network is a bit flaky. From the printer it will only connect to one of the PCs, not the other or either iPad. This carries over from the previous model but that had the advantage of Ethernet connectivity. Using Ethernet the old one would connect to all the PCs but this new one is WiFi only and is no as reliable at connectivity. Scanning of photographs is very basic. There are no software setting for colour correction, balance or backlight correction etc . The results are no so great. Hence we use a dedicated scanner for photos that, even though more than 12 years old, is vastly superior. As discussed above this is the second Brother A3 multifunctional we have owned. When the first ceased to work with a firmware fault we went to another brand. That proved to be a bad move because it was slow, poor quality and had unreliable paper feed and hopelessly bad duplex. We the came back to Brother. That was a big decision for us because we had been left with substantial loss due to the impossibility of fixing Brother’s firmware. Brother support was totally unsupportive on that occasion and we expect no more should the new one go faulty. It’s the modern way and Brother is just like all the rest of the manufacturers who treat users with careless contempt.

Rated 4 out of 5 by from Fab machine, other than no 2 sided scanning Happy with the machine, neat and presentable, all the features you expect except 2 sided scanning
Date published: 2023-09-07
Rated 5 out of 5 by from Great printer Excellent printer, quick and quiet. Prints borderless properly. Colours accurate, copy of commercially printed leaflet hard to distinguish from the original. Copes with paper from A5 to A3 and envelopes (those are the sizes I've used). Ink cartridge pack seems expensive but lasts a long time, so quite cheap per page. Very happy with it.

Rated 5 out of 5 by from Great printer I bought this sometime ago and I am very pleased I did. I always used to use HP but so glad I swapped. At work I use an Epson eco tank, which is messy and very slow. Brother easy to set up and change cartridges only slight issue, which is probably my fault, is when using the back paper feeder for A3.
