5 out of 5 eggsGood Fax Machine For Home Business

Pros: Very easy to set up! I downloaded the software for this FAX from Brothers website and used that with a USB cord connected to my computer for the setup.

I now have a very capable laser printer and a new fax machine for my home office.

It uses the same the toner cartridges as my current Brother laser printer so I know the best results are using only Brother toner.

Cons: The only con I can think of is the cost of the Brother toner compared to all the "compatible" toners on the market (which do not have the print quality of the Brother toners).

Other Thoughts: This unit replaced a MFC Inkjet that was being used as a fax machine in my home office. The MFC became unreliable at sending and receiving fax messages after I switched my phone lines to VOIP, so I replaced it with this. So far, I have been really happy with it. The software should have been included in the package.
