Caution
Insert the toner cartridges gently into the printer. Do not try to lock
them into place by pushing them. Toner cartridges should rest loosely
in the guide rails; they will be correctly positioned when the front cover

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.
