Brother Toner Low: Toner cartridge running low
Also shows as: Prepare New Toner Cartridge
Brother says "Toner Low" (or "Prepare New Toner Cartridge") means the toner cartridge is approaching the end of its life but has not reached it. You can keep printing.
What to try
- Keep using the cartridge while print quality is still good.
- Order a new toner cartridge so it is ready when "Replace Toner" appears.
- Replace only the toner cartridge, not the drum unit.
- If you just installed a new cartridge and the message stays, make sure it is brand new and seated correctly, and clean the corona wire.
When it needs a technician
Brother does not list a service step for this warning.

First steps for any printer error
- Write down the exact code before you do anything else — similar-looking codes often mean completely different things.
- Power the printer off, unplug it for a couple of minutes, then power it back on. A surprising number of transient errors clear here.
- Open the covers and check for paper scraps, packaging material, or anything blocking the carriage.
- Check the cartridges or tanks are genuine, correctly seated, and not empty.
- Confirm the printer is plugged directly into a wall outlet, not a power strip or extension lead.
- Check your model’s own manual — codes are model-specific, and the manual is the authority for your machine.
