The commonest expensive mistake on these machines is replacing a drum unit when only toner was needed. They are separate consumables with very different lifespans, and the printer reports them separately. Toner runs out several times over the life of one drum. Check which the message actually refers to before ordering. Starter cartridges yield less than replacements. See toner cartridges, Brother ink and Brother.
