How do I clear the solid Toner and Error LEDs (light)? The Status Monitor states "Replace Toner" What can I do?

Description of Solution 200000044657

This indicates the toner cartridge is at the end of its life and needs to be replaced.  In order to clear the Toner LED (light), you need to install a brand new, out of the box toner cartridge (TN720 or TN750). 


Brother strongly recommends that customers use only genuine Brother drum units and/or toner cartridges. Each Brother laser printer is designed to work at pre-set temperatures that are matched exactly to each of our individual toner formulations.  Each individual component is designed to work with the other to ensure quality and reliability. Using non-Brother supplies may affect the hardware performance, print quality, and machine reliability. The Brother limited warranty does not apply to any problem that is caused by the use of third party drum units, toner cartridges, or toner.


Do NOT install a previously used toner cartridge. Our toner cartridges are manufactured with a reset lever that moves when installed into the machine.  The movement of the lever is what notifies the machine a new cartridge has been installed and mechanically triggers the machine to reset the Toner LED.  If a used cartridge is installed into a machine, it will not reset the toner status.


-      If the customer is unhappy with the yield of the toner cartridge, refer to the solution I recently installed the starter or a new toner cartridge and I don't think I got the full yield from the toner. What can I do?


-      If the customer installed a brand new, out of the box toner and immediately after installing it the toner LED does NOT clear, refer to the solution: Why do the Toner and Error LEDs continue to appear after i replaced the toner cartridge?
