CHAPTER 5 MAINTENANCE 5. Insert the new Toner Cartridge(s) by positioning it in the correct guide(s). Slide gently into the printer. Do not try to lock or push them in; they should rest loosely in the guide rails. Note that each color cartridge is individually keyed to prevent improper installation. Match each cartridge color label to the corresponding label on the printer. Fig. 5-3 Installing the Toner Cartridges 6. Close the Front Cover. !

They should rest loosely in the guide rails, and will be correctly positioned when the front cover is closed. • The printer may be damaged or may not work correctly if you install consumables other than genuine Brother supplies or if you use refilled toner cartridges. This could void your warranty. • Do not stand the toner cartridge on its end or turn it upside down. • Install the toner cartridges immediately after you remove the protective cover.
