What does “No Toner” mean?

Literally, “No Toner” refers to no toner cartridge inside the Brother printer. But is there really no toner in Brother printer? Not exact! When Brother printer fails to detect the IC chip on a toner cartridge, it will say “No Toner” even thought there is a toner inside. The IC chip on a toner cartridge is the key for printer to recognize the toner cartridge successfully. (Another function of the IC chip is to record the toner level of the toner cartridge.)

You may know that not all Brother toner cartridges come with IC chips. Old toner cartridges like TN-221, TN-225, TN-450, TN-660, TN-850 don’t have IC chips. But they still work with Brother printers perfectly. However, since 2017, all new toner cartridges like TN-730, TN-760, TN-770, TN-223BK/C/M/Y, TN-227BK/C/M/Y come with IC chips. Only when Brother printers recognize the IC chips will they accept these cartridges. So if Brother printers fail to recognize the IC chips, they will give “No Toner“ error message and reject the toner cartridges. There are many reasons why Brother printers fail to recognize the IC chips. These reasons are also the main reasons for “No Toner“ error message. Let’s introduce them one by one.

Reasons for Brother printer No Toner error message

Why my Brother printer says No Toner but there is toner powder at a high level? Generally, you will receive the No Toner error message after installing the new toner cartridge if the printer fails to identify the toner cartridge via the IC chip. There are two main reasons. One is that there is no IC chip in the toner cartridge. Another is that the printer probe and the IC chip are in poor contact. But it doesn’t rule out some other special reasons. If you know some of them, kindly share with us in the comments section. Here is a detailed analysis of why Brother printer says No Toner.

Why Brother printer says No Toner when there is toner installed?

1. Structure of toner cartridge and printer

Supply roller (SR) is a key component on a Brother toner cartridge. It will scroll when the printer is printing. The scrolling SR might separate the printer probe from the IC chip, which makes Brother printer fail to detect the IC chip. So the printer will display No Toner error message.

2. Defective printer probe

The printer probe is the key for printer to detect the IC chip. If the printer probe is deformed or damaged, it cannot transmit the information of the IC chip to the printer even though it contacts with the IC chip. Thus, the printer will misjudge that there is no toner cartridge installed in the printer. And you will receive the No Toner message.

Why Brother printer says No Toner after replacing toner?

1. Wrong model of toner cartridge is installed

Assuming the printer is a lock, the toner cartridge is equivalent to the key. So printer should match the corresponding toner cartridge for normal use. In most cases, the same toner cartridge series can be compatible with multiple printers, but one printer can only use one or two series of toner cartridges. For example, the toner cartridges for Brother MFC-L3770CDW should be Brother TN223 and TN227 series. However, if you mistake TN760 as the Brother MFC-L3770CDW toner and install TN760 into the printer, you may receive No Toner error message.

2. No /incompatible IC chip inside the toner cartridge

Like installing the wrong toner cartridge, the wrong or incompatible chip will also disable the printer from recognizing the toner cartridge, thus giving the error message No Toner. Please note that the damaged, incorrect, or unupgraded IC chip could cause the No Toner message Brother printer.
Plus: If you want to avoid No Toner due to the unupgraded IC chip, you can turn to your toner supplier for help or disable the automatic printer firmware upgrade according to the blog-Three Ways to Disable HP Printer Firmware Update. Another point worth noting is that disabling the automatic printer firmware upgrade does not mean the printer firmware can no longer be upgraded. It means that when the printer prompts you to upgrade the firmware, your firmware will not be automatically upgraded. Also, you can contact brother toner supplier to get firmware versions if you want to upgrade the firmware after disabling the printer firmware upgrade.

3. Bad IC chip contact

The printer may not detect the toner cartridge if there are gum, stains, oxidation, or other foreign matters on the surface of the IC chip, even though the printer probe contacts the chip. As a result, the printer may display the No Toner error.

The difference between Brother “No Toner” error message and Brother “Replace Toner” error message

Brother printer No Tone and Brother Replace Toner error message refer to different things. They are two Error Warnings for the Brother printer. The former means that there is no toner cartridge in the printer (or the printer fails to identify the toner cartridge because of no IC chip or bad IC chip contact), while the latter refers that the printer recognizes that the toner level of the Brother toner cartridge is too low to guarantee the printing quality, and prompts the printer user to replace it.

The IC chip is why Brother printer saying No Toner after replacing the old toner.

  1. This easiest way to fix the “No Toner” error -> take the IC Chip off the original Brother toner cartridge and then remove the IC Chip on the new toner cartridge and replace it with the Brother IC Chip. Should fix issue.

  2. I had this error after a power cut, and solved it with the help of the app. I took it all the toners and turned my unit off. I turned it back on with none in then loaded thirteen in one by one. As each was replaced it knocked that colour of the mounting list. It did fail to install all toners so the error remained but the app showed which were accepted. I then checked the toner connection chips. One of which I improved the connection. The last toner was still not being seen so I tried a new cartridge and this was accepted. Back to a working unit!
