Has anyone had luck using 3rd party Toner with their Brother printer in the last year? I know the firmware has changed in the last few years to prevent this, but I am wondering if 3rd party manufacturers have managed to circumvent the firmware changes.
I would bet you're fine. I sold printers for a while and brother generally didn't get up to that kind of nonsense. Don't know for sure though.
Recently they've started intentionally reducing print quality with third party toners.
