Troubleshooting
Check whether the output is still acceptable
You can continue printing while the print quality remains acceptable.
Have a replacement ready
Obtain a compatible toner cartridge. Replace the current cartridge when print quality becomes unacceptable or Replace Toner appears.
When to contact support
Editorial guidance: The warning alone does not call for professional servicing. If a new, correctly installed cartridge does not resolve a later replacement message, contact Brother support.
Editorial note: There is no reliable remaining page count in this guide. Toner and drum are separate supplies; this warning concerns toner.
