			<blockquote>When connected to the internet, some Brother printers suffer a firmware downgrade that degrades the printing quality when using third-party toner. This proves that these printers have a back door which lets Brother control them.

			As a general precaution, users should make sure their printer can't connect to the manufacturer's server, for example by shielding it from the internet by a firewall. This will not restore the ability of printers to use third-party toner if they have already lost it, but will prevent any future downgrades. All printer manufacturers are concerned, not only Brother.</blockquote>
