Brother HL-2700CN series User Manual page 112

Slide the toner cartridges into the printer gently. Do not try to lock them into the printer by
pushing them. They must stay loosely in the guide rails so they will be properly positioned when
the front cover is closed.
If you use consumable items other than genuine Brother supplies or if you use refilled toner
cartridges, the printer could be damaged or might not work properly. This may void your
warranty.
Do not stand a toner cartridge on its end or turn it upside down.
ROUTINE MAINTENANCE 5 - 7
