Locate the toner cartridge and open the printer access panel

The toner cartridge sits inside your Brother printer behind a front panel or side door. On most Brother models, you'll see a latch or handle on the front of the machine — pull or slide it toward you to open the access panel. The cartridge will be visible when ready inside, usually held in a horizontal slot.

Before you touch anything, turn off the printer and let it sit for a few minutes. The fuser unit (the part that heats and bonds toner to paper) gets hot during printing and can burn your fingers. You don't need to unplug the machine, but powering it down prevents accidental printing while you're working inside.

Remove the old cartridge by pulling the green or blue tab

Inside the printer, you'll see a colored tab — usually green or blue — sticking out from the cartridge. Grab this tab firmly and pull it straight toward you. The cartridge will slide out of its slot. Don't worry if you hear a click or feel resistance; that's normal. The cartridge is designed to come out this way.

Set the old cartridge on a clean surface or directly into a bag. Toner powder is messy but not toxic. If you spill some, wipe it up with a damp cloth rather than a dry one, which will spread the powder around. Some people place newspaper under the cartridge before removing it to catch any loose toner.

Key Takeaways

  • Turn off your Brother printer and wait a few minutes before opening the access panel, since the fuser unit gets hot during printing.
  • Pull the colored tab on the cartridge straight toward you to slide it out of the printer.
  • Remove the protective tape from the new cartridge before inserting it, or the printer will not dispense toner.
  • Slide the new cartridge in until you hear a click, which means it is seated correctly in the slot.
  • If your printer shows a toner low warning but the cartridge still has powder, you may need to reset the toner counter through the printer menu.

Unpack the new cartridge and remove the protective tape

Brother cartridges come wrapped in plastic and sealed with tape to keep toner from leaking during shipping. Remove all the plastic wrapping first. Then look for a long strip of tape — usually orange, yellow, or clear — running along the side or top of the cartridge. This tape covers the opening where toner exits into the printer. Pull this tape completely off before you insert the cartridge, or no toner will reach the drum and your prints will come out blank.

Some models have a second piece of tape covering a small hole on the cartridge body. Remove that too. Check the cartridge on all sides to make sure you haven't missed any tape. The instruction sheet that comes in the box will show you exactly where the tape is located on your specific model.

Insert the new cartridge and listen for the click

Align the cartridge with the empty slot inside the printer. The cartridge has a shaped end that only fits one way, so you don't have to worry about inserting it backward. Slide it in smoothly and steadily until you feel it seat fully in the slot. You should hear a distinct click or feel a snap as the cartridge locks into place. This click means the cartridge is properly connected and the printer recognizes it.

If the cartridge doesn't click into place, pull it out and check that you removed all the protective tape. Reinsert it and try again. Don't force it — if it's not sliding smoothly, something is blocking it or the tape is still in the way.

Close the access panel and power the printer back on

Push or slide the access panel closed until it latches. You'll usually hear or feel a click when the panel is fully shut. Turn the printer back on using the power button. Most Brother printers will run a brief initialization cycle — you may hear the printer move and whir for a few seconds. This is normal and means the printer is recognizing the new cartridge.

Wait for the printer to finish its startup sequence before sending a print job. If the printer displays an error message about the cartridge, turn it off, open the panel again, and make sure the cartridge is fully seated. Sometimes a cartridge that looks locked in place isn't quite all the way in.

Reset the toner counter if the low-toner warning stays on

After you install a new cartridge, your Brother printer should automatically reset its toner counter. However, some models don't do this automatically, and the low-toner warning light may stay on even though you've just installed a full cartridge. If this happens, you can reset the counter through the printer's menu.

The exact steps vary by model, but the general process is: press the Menu button on the printer's control panel, navigate to Toner or Supplies, find the Reset Toner option, and confirm. Your printer's manual will show the exact button sequence for your model. You can also find this information on Brother's support website by searching for your printer model number plus "reset toner counter."

Store the old cartridge or recycle it

Brother cartridges can be recycled through several programs. Brother itself runs a cartridge recycling program where you can mail used cartridges back to them for free — you'll find the program on their website. Many office supply stores like Staples also accept used cartridges for recycling, sometimes offering a small discount on your next purchase.

If you're not ready to recycle when ready, store the old cartridge in a sealed bag or container in a cool, dry place. Toner can clump if it gets damp, which makes the cartridge unusable. Don't store cartridges in direct sunlight or near heat sources. If you're keeping it as a backup, label it with the date so you know how old it is.

Frequently Asked Questions

What happens if I forget to remove the protective tape?

Your printer will print blank pages because toner can't reach the drum. Open the access panel, pull out the cartridge, remove the tape, and reinsert it. The printer should work normally after that. Check a few test pages to make sure toner is flowing properly.

Can I use third-party or refilled cartridges in my Brother printer?

Yes. Brother printers accept compatible third-party cartridges and refilled cartridges, though the printer may display a warning message that the cartridge is non-genuine. This is just a notification and doesn't affect printing. Some people use third-party cartridges to save money, while others prefer original Brother cartridges for reliability.

How do I know which cartridge model to buy for my printer?

Look at your printer's model number (usually on the front or back of the machine) and search for it on Brother's website or your cartridge retailer's site. Each Brother model uses specific cartridge numbers like TN-660 or TN-880. Buying the wrong cartridge won't fit in your printer, so double-check the model number before ordering.

Why does my printer say toner is low when I just installed a new cartridge?

The printer's counter didn't reset automatically. Use the Menu button to find the Reset Toner option and confirm it. If the warning persists after resetting, the cartridge may not be fully seated — remove it and reinsert it until you hear the click.

Is toner powder dangerous if I spill it?

Toner is not toxic, but it's messy and can irritate your lungs if you breathe in a large amount of powder. Wipe up spills with a damp cloth and wash your hands afterward. If you spill a significant amount, open a window for ventilation while you clean it up.
