There is a difference in toner cartridges
Reviewed in the United States on March 25, 2020
We go through a lot of toner in my shop. My ordering person used to purchase "whatever fit" our Brothers printer/fax/copier machines (we're a medical supply house and get lots of faxes in particular). And because of my order person's lackadaisical approach to ordering toner, we had a lot of "failures."
Then we hit on HaloFox. Halofox cartridges are long-lived, always work, never print unevenly, never blotch, and always work. Nor do they cause a mess inside the machine (unlike one refill we'd bought that dumped the entire reservoir of toner into the guts of one printer, ruining my most expensive printer--don't fool yourself, you can't vacuum that stuff out. We tried).
So now we only buy from HaloFox.
