My Brother Toner Light Stays On With New Toner (What To Do)

 

Quick Answer:

Try the following methods if your Brother toner light stays on with new toner:

  1. Use an unused and genuine Brother toner cartridge.
  2. Install the cartridge properly: remove it from the drum and then reinstall it.
  3. Clean the corona wire: slide the green tab inside the drum unit from side to side several times to remove any debris, then return it to the home position.
  4. Reset the printer: hold 'Go' button and turn on, release, press 'Go' twice, then five times and close cover.
  5. Check for firmware updates: Visit the Downloads section on the Brother website, find the Firmware Update Tool, and verify the current firmware version.

If none of these work, contact Brother support.


Toner Light Issues After Brother Cartridge Replacement

The toner light on your Brother printer stays lit even after you've put in a new toner cartridge.

This problem can arise from several factors.

Here's a troubleshooting guide to assist you in fixing this issue.


Confirm Cartridge Is Unused

Confirm that the replacement cartridge is completely unused and hasn't been previously installed in this or any other printer.

This verification is essential because only a new, unused cartridge can trigger the required reset mechanism within the printer. 

Using a cartridge that has been previously used may lead to the persistent Toner LED issue.


Use Genuine Brother Toner

It's highly recommended to use genuine Brother toner cartridges. Each Brother laser printer is precisely calibrated to work with our unique toner formulations at specific temperatures.

Brother laser printers are designed for optimal performance with their specific toner and components. 

Using non-Brother supplies may affect print quality and machine performance.


Confirm Proper Installation

To confirm optimal printer performance, verify that the toner cartridge is properly seated in its designated slot.

  • Open the printer's front cover and remove the drum and toner assembly.
  • Remove the toner cartridge from the drum.
  • Next, insert the toner into the drum.
  • Finally, put the toner and drum assembly into the machine and close the front cover.
  • Turn on the printer and print a test page to confirm the cartridge is functioning correctly and the error messages have ceased.

Interesting Note: Interestingly, there are unusual cases where the toner light remains on when replacing a standard Brother toner with a high yield one. However, switching back to the standard toner often resolves the issue after several attempts. In this case, it’s best to reach out to Brother Customer Support for further assistance.


Reset Internal Printer Settings


You can also resolve the persistent toner light issue through a reset of the printer’s internal settings.

  • Install the new toner.
  • With the printer off, open the front cover.
  • Press and hold the 'Go' button while turning the printer on.
  • Once all three lights light up, release the 'Go' button.
  • Press 'Go' twice to make all lights turn solid.
  • Press 'Go' five more times, causing all lights to turn off except the 'Ready' light.
  • Close the front cover.

Clean Corona Wire

Another reason for issues could be the corona wire needing cleaning.

  • Open the front cover of the printer and wait at least 10 minutes to allow the machine to cool down.
  • Carefully take out the drum unit and toner cartridge assembly.
  • Place the drum unit and toner cartridge on a flat, clean surface with disposable paper underneath to catch any spilled toner.
  • Do not touch the electrodes to prevent static damage to the printer.
  • For cleaning the primary corona wire, carefully move the green tab several times back and forth inside the drum unit.
  • Make sure to return the green tab to its home position to avoid vertical stripes on printed pages.

Check Firmware Version

If the issue persists despite using a new, unused genuine Brother toner cartridge, make sure your printer has the latest firmware version

  • Go to the Downloads section on the printer manufacturer's website.
  • Check for the Firmware Update Tool in the Downloads section. Click on it to access detailed information and verify the current firmware version.
  • If the firmware version on your Brother printer is older than what is available, proceed to update it. Follow the installation instructions provided on the download page.

If you've followed all the steps, including checking the firmware version, and the issue still continues, it's time to get in touch with Brother Customer Support.

They can provide you with further assistance and guidance to resolve the problem.
