How to Remove “Replace Toner” Message on Brother Printers?

When a Brother printer displays a “Replace Toner” message, it means the toner cartridge is low and will need to be replaced soon. However, there are a few troubleshooting steps you can try before replacing the cartridge.

How to Remove "Replace Toner" Message on Brother Printers?

Determining Which Cartridge Needs Replacement

The first step is to identify which toner cartridge the printer is referring to when it shows the “Replace Toner” warning. Brother printers that use multiple cartridges will specify “Toner Black”, “Toner Cyan”, “Toner Magenta”, or “Toner Yellow” on the LCD display. Make a note of which color toner needs replacement.

Checking Toner Levels

Open the front cover of the Brother printer and locate the toner cartridges. Most Brother toner cartridges have a small window on the side with indicates showing the amount of remaining toner.

Check the fill level – if it is below the dotted line near the “Replace Toner” message, then the cartridge does need to be replaced soon. If the fill level is above the line, the cartridge may still be able to print and the warning message can sometimes be temporarily cleared.

Cleaning the Corona Wires

Before replacing the Brother toner cartridge, try cleaning the internal corona wires:

  1. Open the front cover of the printer.
  2. Gently remove the toner cartridge(s) and drum unit.
  3. Locate the corona wires (thin wires with a protective coating).
  4. Use the included cleaning tool or a dry cotton swab to gently wipe the coronas wires to remove dust and debris.
  5. Reinstall components and close front cover.

Cleaning the sensitive corona wires can help improve print quality issues caused by dirt buildup and may allow more toner to transfer to the drum unit properly.

Resetting the Replace Toner Message

On most Brother laser printers, you can temporarily reset the “Replace Toner” warning message to continue printing without replacing the cartridge using the steps below:

  1. Press the Menu button on the control panel.
  2. Select “General Setup” using the arrow buttons.
  3. Scroll to “Replace Toner” and select it.
  4. Choose the color cartridge you want to reset.
  5. A confirmation message will appear allowing you to reset the replace toner message.

After resetting the message, you can continue printing but print quality may decline as toner gets lower. The warning message will return after printing approximately 50-100 more pages.

For Brother inkjet printers, you need to physically replace the ink cartridge as there is no way to reset the replace ink message.

Checking Other Issues Before Replacing Toner

Here are a few other issues to check that could be incorrectly triggering the warning message on Brother printers:

  • Run a Drumdot Print Test to confirm that the drum unit is not worn.
  • Make sure you are using official Brother TN cartridges – third party toner cartridges may cause issues.
  • Check that the cartridge model numbers match – using the wrong model cartridge can cause printer errors.
  • Inspect inside the printer for paper jammed near the toner cartridge area.
  • Clean the printhead glass strip inside the drum unit with a dry cotton swab if printer has print quality issues.

Addressing other printer problems first before installing new toner cartridges can often save unnecessary expense on replacement Brother toner.

How to Replace Toner Cartridge in Brother Printer

Once you have determined that a Brother toner cartridge does need replacement, carefully follow these steps to install a new cartridge:

Supplies Needed:

  • Replacement Brother TN toner cartridge
  • Paper towels or rag
  • Clean, dry cotton swabs
  1. Open the front cover of the printer.
  2. Gently pull out the drum unit assembly.
  3. Hold the green handles on the toner cartridge and lift up and out.
  4. Unpack the new toner cartridge but do not open the toner seal or remove protective cover yet.
  5. Slowly rock the new cartridge side-to-side 5-6 times to distribute the toner evenly inside.
  6. Pull the seal completely out to open the toner outlet port. Remove any protective cover.
  7. Line up the cartridge guides in the printer and insert the new cartridge.
  8. Insert the drum unit back into the printer and close the cover.

The first few pages may print with light toner until filled, but print quality should quickly return to normal.

Be very careful not to spill toner and immediately clean any spills inside the printer using paper towels to soak up toner. Change clothes immediately if toner gets on your skin or clothing to avoid permanent staining.

Conclusion

The “Replace Toner” alert on Brother laser printers indicates toner is running low, but does not necessarily mean the cartridge needs immediate replacement. Check the toner levels visually first before replacing cartridges. Cleaning coronas wires inside the drum unit can often help clear up print quality problems that trigger the warning. On most models, the reminder message can be temporarily dismissed in the menu settings to squeeze out remaining toner. When print quality degrades and toner cartridges read empty, carefully replace them with new Brother branded cartridges, while taking precautions not to spill any toner. Following proper maintenance procedures helps ensure Brother printers continue printing high quality documents over the long run.

  9. Why does my Brother printer say drum error?
    The drum error indicates the OPC drum unit inside the printer needs replacement from extensive usage and wear over time. Brother printers stop printing pages when the drum unit’s page capacity maxes out at 20,000-30,000 pages.
  10. How do I reset the drum counter on my Brother printer?
