I just replaced the toner cartridge and the LCD continues to display the message "Toner Low" or "Replace Toner".
If the machine's display continues to show the Toner Low or Replace Toner error indication after installing a new toner cartridge, follow the steps below to resolve the issue.
Verify that you didn't replace incorrect consumable by mistake.
When replacing the toner cartridge, you MUST install a brand new, unused toner cartridge in order to reset the toner status. Swapping toner cartridges from one machine to another or installing a partially used toner cartridge may cause this issue. If you install a partially used toner cartridge, your Brother machine is unable to recognize toner consumption correctly which will cause this issue. Therefore, when you replace the toner cartridge, use a brand new toner cartridge, not a partially used toner cartridge from another machine.
Verify the toner cartridge is installed correctly.
If you install a new toner cartridge but the "Toner Low" or "Replace Toner" error indication remains, the toner cartridge may not be installed correctly.
Reinstall the toner cartridge, referring to the instructions on how to replace the toner cartridge. > Click here to see how to reinstall the toner cartridge.
Confirm that you have installed both a toner cartridge and a drum unit in the machine.
