Not up to Brother standards

I have an older version of this product that works much better.  I expected this one to be at least as good.  However is is constantly jamming when double side printing.  I'm disappointed with this product.

Do not buy this printer. Have been on phone with Brother for hours at a time for 2 months they don't seem to know what the problem is. Save your money and buy a different brand.

After 50 pages, the pages started showing a grey background. I cleaned all the printing parts as directed by the brother manual but the grey background did not disappear which made me conclude that the toner was not really compatible with my brother printer.

I am sorry, but for some reason these cartridges did not fix my brother printer....not sure why, but they just didn't.

I use Brother's own brand because they seem to last the longest and I have never had any probelms.  I will conitinue to do so in the future.  Never had any problems.

Well this is the most recent of several high yield Brother toner cartridges of various colours I have bought in the past two years that has leaked. As soon as I installed it, it took a big dump in my 9840CDW MFC. Black toner was pouring out of the centre of the cartridge and coating the center of the roller and spewing throughout the inside of the printer. Back to Amazon it went and I replaced it with a regular yield Brother cartridge which at least initially is working fine. I had to use a whole can of compressed air to clean the mess inside my printer.  If I had not poured so much money into this printer I would replace it with another brand. There is obviously a systemic problem here and I have not heard that Brother is addressing it.

Just as good as Brother at a quarter of the price!

The most expensive printer we have and it causes the most problems. Always losing connection from our computer. The brother solutions center is on speed dial. That's how awful our experience has been. Highly Disappointing.

This toner does NOT work with Brother MFC7860DW printers.  The message window fails to recognize that the toner is in the machine.  For a very short time, it actually made a few copies when I just ignored the message that I needed to replace my toner, but very soon the printer stopped working altogether.  Don't buy this product.

I paid $400.00 for this machine. It prints OK. It scans better than the older machine but it cannot self-feeder 8.5x11 sheets straight when scanning multiple pages. Same for any function requiring feeding multi-pages. A single driving wheel instead of 2 is tge problem. After all the trouble with this second Brother machine, I am now done with Brother machines of any kind for life.

This drum unit fit in my brother printer just fine but when installed the printer still indicated the message "replace drum" so it did not correct my problem. I also tested it to see if it printed a page and it did with poor quality and a vertical stripe on the page. Not acceptable. I'm ordering a drum made by Brother.  Don't waste your time or money on this poor product. Returning it.

I bought this SA129 foot over others on Amazon because it claimed to be a genuine brother product. I'm not convinced. It came in a small plastic bag without any instruction or Brother packaging. I haven't tried it yet so I can't speak to its functionality but I'm pretty disappointed from the start.

Not very happy with this printer. The print quality is average and wireless connectivity is poor. What irritates me the most is it keeps printing junk characters at random. Tried all forums / support for solution but brother is just not providing a proper answer. Very annoying issue and leads to a ton of papers wasted.

I hate it! I am very disappointed in this Brother printer. I had a Brother printer before this one and decided when it started jamming up that I would replace it with another Brother. This one prints slow and you cannot print double sided when using Chrome browser. Also, I have been using it for less than 2 months and I already need a replacement toner - I don't print that much.

The printer heads jam incessantly. It is a problem with Brother printers overall. Do a search for Brother printer heads plugged and you will see what I mean. DONT RUN THE PRINTER HEAD CLEANING! It just dumps ink onto a sponge and then clogs them even worse. Waste of money.

Nothing works properly.
Have purchased Brother faxes & printers only, for over 20 years.
This model represents a NEW LOW for BROTHER - Won't take thicker than average paper & can't feed it straight.
Don't think I will consider another Brother product in the future.

I came very close to purchasing this labeler. I find that brother products are not reliable and they have many problems especially fax machines and printers. I have used brother labelers before and thought I would give it a chance. After reading other reviews and knowing the amount of tape other brother labelers waste, I decided probably best to stay away. I gave it two stars only because the design is nice and the price is cheap, but they obviously get you by making you buy a lot of tape. After doing some research and looking at labelers in stores, I've decided to go with a DYMO labeler instead.
