Brother Toner Reset – MFC-L8850CDW L8600CDW and L9550CDW

For some reason every now and again when a new toner is installed in the Brother MFCL8600CDW  MFCL8850CDW and MFCL9550CDW the reset switch isn’t triggered and the toner counter doesn’t get reset. The following is a manual reset for you printer that you can use to reset the counter.

  1. Open the front cover of your Brother MFC laser printer where you can access its toner cartridges.
  2. Press and hold the STAR (*) button for about 5 seconds to see the toner menu on the screen (it will not be lit up – you can light it up by selecting the fax option with the cover closed and remembering where it is).
  3. Select the toner you need to reset. Press “yes” to reset the selected toner cartridge. Repeat for each toner cartridges colour as required.
  4. Close the front cover.

DONE.Note: for selecting the correct toner you need to understand the cartridge code system Brother uses:

  • Black is K, Magenta is M, Cyan is C and Yellow is Y
  • TNR = toner
  • STR = starter cartridge (the toner cartridges that came with your printer)
  • STD = standard toner or TN341
  • HC = high yield toner or TN346

Please leave a comment if you find this guide useful or there is anything I can add to it to make it easier to follow.

This has been tested on the MFC-L8850CDN but should also work on MFC-L8600CDW  and MFC-L9550CDW as they are the same series.

Some users have worked out that if there are any jobs in the printers memory it will not let you into the reset menu.
To fix the please Switch off the printer and remove the USB or network cable. If you use wifi you may have to disable the printers wifi.

After that power up the printer and try the reset again.

    Thank you. I wish I knew what the default toner # was but this has allowed me to use my heavy duty printer for the first time in 4 months. Bought a refill kit because a black refill cartridge is $70 which is ridiculous but couldn’t figure out how to reset. Successful test page is now sitting in my lap. Eternal gratitude.

  2. Christopher says:

    I cannot get the toner reset menu to show up by pressing the location where either the red “X” would be, or the “*” under the faxing menu is. I open the toner access panel, pull the tray out, press either location and hold, and nothing. I have the MFC-L8850CDW…

      What model is your printer?

      FYi you may need to hold down the star/ asterisk key for about 5 seconds. Please let me know how you get on.

          Hi John

          On the MFC-L8850CDW it is the Star key (right next to the X key) you will need to hold it down for about 5 seconds.

          Note BE SURE TO OPEN THE FRONT TONER DOOR. If that doesn’t work just pop the toner tray out a little and try again.

          1. Chris says:

            I figured out Johns problem. The instructions you gave work but only if you clear out the current print job. Otherwise the printer sits in “waiting for info mode” and does not register the front toner door is open.

          2. Sylvie says:

            I have the same printer MFC-L8850 CDW, tried EVERYTHING everybody wrote and nothing happens when I press the star button. Did someone tryed it with the same printer and figured it out ??? Thanks

            Hi Sylvie

            Other users have worked out that if there are any jobs in the printers memory it will not let you into the reset menu.
            To fix the please Switch off the printer and remove the data cord USB or network. If you use wifi you may have to disable the printers wifi.

            After that power up the printer and try the reset again.

            Also the key needs to be pressed for about 5 seconds.

      John same issue — here’s what you do: 1. Open the door where toner is located 2. turn printer off 3. turn printer back on 4. you should see a message telling you to close the door 5. now press the * key (from the phone key pad which lights up when you click on the fax to locate do this before shut down) for 5 seconds and the menu does appear! Yeah, this was very frustrating!

  3. Jonathan says:

    It is worth noting that on the MFC-L8850CDW, you need the memory empty before the star menu will work. Its quite often the case on a lot of brother machines. If you have items in memory the toner reset menu doesnt want to appear.

    1. Uma says:

      I tried all of these solutions and still no luck. This is very annoying as I have not even had this copier for 6 months and I am getting recurring issues that involve strange resolutions like “Turning it on and off while leaving the tray open while the room is exactly 65 degrees”

      When you say clear the memory, what exactly do you mean? I removed all print jobs for the printer from our server. Rebooted multiple times, removed the network cable multiple times so I am really out of ideas about this.

      Is there another strange method that I can try to resolve this?

      1. Easyink Support says:

        The best way to do the reset if you are having issues is to remove the network cord turn off and unplug.
        Plug the printer back in and do the reset (with the network still removed).

        If that doesn’t work I am out of ideas – there maybe another fault.

  4. Jan says:

    I have mfc-l8850-cdw. what worked for me is: open door. You should see on screen: !cover is open – scrolling across. Beside that is the word ‘detail’ Press ‘detail’. Next screen is a pic of printer with the red ‘x’. Now press where the * button is (even though you can’t see it – figure out where it is). Hold it for 5 seconds and reset menu comes up.

    1. Jacqueline says:

      Thank you Jan, I have tried so many things from the tech support that sold the toner to utube videos none worked…. My copier was out of commission for 2 weeks….
      BUT YOURS DID!!!!! THANK YOU.

    2. HOWARD says:

      Yours was the instruction that got me over the hump with my MFC-L8600CDW to success, after two days of trying everything else! Thanks, you are the best!

    3. Josh says:

      Holy crap that was frustrating! I have a Brother MFC-L5850W but this was still the most info I could find on the issue. With mine you have to hold down the pound # not the star. Thanks for the help!

  5. Tess says:

    Sweet this worked like a charm Jan! Thank you.
    So frustrating how there is still so much toner left in the cartridge. What a waste.
