Why does the message "Replace Toner" continue to appear on the LCD display after I replaced the toner?

Description of Solution 200000040783



1.  Look at the LCD and read all the lines of the message currently on the display.  Be sure to read the entire scrolling message.  (Ex: Replace Toner. Open the front cover, replace toner cartridge. Black (K))


Confirm the color toner cartridge indicated on the LCD is the same color as the toner cartridge that was replaced.  It is possible that after the replacement toner cartridge was installed, a new message appeared for a different color toner and another color now needs to be replaced.


2.  Verify you installed a NEW, out of the box toner cartridge (TN221 or TN225) from a sealed foil bag.


When replacing a toner cartridge, you should install brand new, out of the box toner cartridge to reset the toner status.  You should NOT install a previously used cartridge that was already installed into another machine or a TN starter toner cartridge that comes with the machine.


Brother toner cartridges are manufactured with a reset lever that moves when installed into the machine.  The movement of the lever mechanically triggers the machine to reset the toner status.  If a used cartridge or a TN starter cartridge is installed into a machine, it will NOT trigger the machine to reset the toner status.


Brother strongly recommends that customers use only genuine Brother drum units and 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.


3.  Verify the drum unit and toner cartridge are installed correctly:


a.  Lift open the top cover using the indented handle in the center until you hear a click.


NOTE: Failure to completely open the top cover when removing and installing consumables may cause severe damage to the machine. The top cover is completely open when the cover locks in place and does not require support from you.




b. Take out the drum unit and toner cartridge assembly. Each drum unit and toner assembly can be removed by grasping the center of the drum and toner assembly and pulling it straight up. Place the drum unit and toner cartridges assemblies on a piece of disposable paper or cloth to avoid spilling and scattering the toner. Repeat this step for all 4 drum unit and toner cartridge assemblies.




c. Reinstall the drum unit and toner cartridge assemblies into the machine by sliding them into the correct slot by matching the toner cartridge color to the same color label on the machine.




d. Close the top cover. You will hear a loud click when the top cover is closed firmly.


4.  Confirm if the "Replace Toner" status continues to appear.


-  If the "Replace Toner" status no longer appears, the issue is resolved.


-  If the "Replace Toner" status continues to appear, the machine has a one year limited repair or exchange warranty.  If the machine is in warranty, contact Brother Customer Service at 1-877-Brother (1-877-276-8437) Monday through Friday, excluding holidays, for warranty options.
