I can confirm this. A Brother HL-L3270CDW color laser worked fine with third-party toner at first, but would not recognize it after a firmware upgrade. I tried three different sets of cartridges, including different brands - none were recognized, and there's no way to revert to a previous firmware version.

That was the last Brother color printer I'll buy, unless they go back to accepting generic toner.

There's a way to rollback the firmware for this family of models, check out on the internets. I did it, and it solved the same issue for me.

What are the alternatives then? Brother is often cited as the brand that is the most tolerant of generic consumables and with the least anti-consumer practices. But now that even Brother plays this game...

I have that printer, and I was about to buy some third party toner for it (first time). What firmware version disabled third-party toner support? Looks like we have 1.35. I just disabled automatic "check for updates" but maybe it's too late.

So what do we buy instead? Brother was the last not-evil printer company I knew of.
