Louis Rossmann accuses Brother of becoming an "anti-consumer printer company" due to actions taken regarding third-party toner and color registration functionality.
A firmware update, W1.56, was reported to cause the color registration feature to stop working on a Brother printer when using third-party cartridges.
Brother denies intentionally disabling printer functionality with third-party toner and ink.
While official Brother cartridges may offer better performance, users claim that Brother does not block the use of alternative cartridges.
