Brother Printer Says No Toner After Replacing, What to do? If the toner cartridge or toner cartridge and drum unit assembly is not inserted correctly, the No Toner message occurs.
Remove the drum unit and toner cartridge assembly. Remove the toner cartridge from the drum unit and replace it with the new toner cartridge. In the machine, replace the toner cartridge and drum unit component.
Follow the instructions below to resolve the Toner Low, Replace Toner, or Toner Ended problem signal on the machine’s display or LED after inserting a new toner cartridge.
Verify that you didn’t replace incorrect consumable by mistake
The toner cartridge and the drum unit are two different consumables for the Brother machine. Ensure that just the toner cartridge is replaced, not the drum unit.
The Brother machine’s toner cartridge and drum unit are two separate consumables. Make sure you just change the toner cartridge and not the drum unit.
The toner is transferred to the paper by the drum unit.
The laser printer loads toner onto a roller within the drum unit known as the “photosensitive drum,” and then uses heat and pressure to adhere the toner to the paper, printing letters and graphics.
The Brother machine detects the drum unit’s quality decrease automatically to maintain optimum print quality. You must replace the drum unit if the Brother machine displays the “Replace drum” problem message.
Verify you are using a new Brother toner cartridge
To reset the toner status, you must replace the toner cartridge with a brand new, unused genuine Brother toner cartridge. This problem can be caused by moving toner cartridges from one machine to another or installing a partially used toner cartridge. Brother devices monitor toner use to ensure the best picture quality for the best print quality. If you utilize a partially used toner cartridge, your Brother machine will be unable to appropriately recognize toner use, resulting in this problem. As a result, use a brand-new toner cartridge instead of a partially used toner cartridge from another machine when replacing the toner cartridge.
Verify that you are using a genuine Brother toner cartridge
Use only new genuine Brother brand consumables that are precisely manufactured to ensure high print quality and optimum performance. When you print with non-Brother authentic toner cartridges, you risk lowering not only the print quality, but also the machine’s performance and life. Any repairs required as a result of damage to the drum unit or other parts of the machine caused by using non-Brother brand products will not be covered by the Brother limited warranty.
Verify the toner cartridge is installed correctly
If the “Toner Low,” “Replace Toner,” or “Toner Ended” error indications persist after installing a new genuine Brother toner cartridge, the toner cartridge may not have been installed correctly.
Refer to the instructions on how to replace the toner cartridge when reinstalling it.
