Brother HL2270DW Toner Reset

So I handle all the IT where I work, which includes anything even remotely computer related. I took a day off, and when I returned the next day the shipping / receiving person came to me and said he had a printer problem that I needed to look at. He added that it was not urgent because he was able to print since he borrowed the owner’s printer.
HUH?

The printer in question was a Brother, model HL2270DW. Apparently, it just stopped working and reported the toner was out. A new cartridge was installed but the printer still would not print. (I think there is more to the story than this.)

After messing around with the printer for an hour, I stumbled on this solution! by phiolle
