Stop Brother laser printer ‘Replace Toner’ messageJanuary 23, 2015
Printer companies want you to buy their toner, and they want you to replace that toner long before it runs out. They do this by various means; typically beeps, popup screens, warning messages on the display panel of the printer etc. How they gauge when the toner needs replacing varies by manufacturer too — some alert you based on number of pages printed (assuming that you are printing an entire page of solid toner every time), others use a laser beam through a hole in the printer cartridge (true! — see this video: https://www.youtube.com/watch?v=PK9qUeH1AVU), and still others by means I’m not aware of.
My Brother MFC 9210CN (and more recently, my MFC 9330CDW) multifunction laser printer warns me when it decides the toner is running low, and if I don’t replace the toner (either black only or all FOUR colour cartridges at once) within a time/usage frame it considers acceptable, it locks me out from printing by beeping a lot, displaying a ‘Replace toner now’ message on the printer and my computer screen, AND by physically NOT printing my print jobs.
Well, I’m sick of it. There’s plenty of toner left in the cartridges (since when do I fully print a page as I would if I was printing photos every time?). And at more than $100 each (I have five in the machine), replacing cartridges every few months is not cheap.
Off to Google…. where I found out how to reset my printer so that it thinks my cartridges are still fine. I found the answer here: http://blog.tonerboss.com/how-to-reset-brother-mfc-9320-mfc-9120cn-and-mfc-9010cn/, and it worked. I decided to take photos of the controls and write full instructions for anyone else trying to do this. Maybe I can get another 500+ pages out of my toners this way.
The instructions for the MFC 9330CDW come after the instructions for the MFC 9120CN.
How to reset the toner cartridge settings on a Brother MFC 9120CN
- Make sure the printer is turned on.
- Open the cover using the blue ‘handle’ at the front of the machine. You don’t need to open it much — you’re not getting into the cartridge area and you’ll need to access the control panel.
- Press the Clear/Back button on the control panel.
- Press the up or down arrow key to scroll through the list of toners. Note: K = Black, M = Magenta (pink), C = Cyan (blue), and Y = Yellow; each has an option for STD and STR.
- When you get to the toner you want to reset, press the OK button. I chose K. TNR-STD to reset the message about my black toner cartridge and allow me to print again.
- You get two options for your selected toner — 1 to reset and 2 to exit. Press 1 on the numeric keypad of the control panel to reset the toner.
- Close the cover. The printer will go through its warm up cycle again and your beeps, messages, etc. should be gone AND you should be able to print again using your existing cartridge.
Of course, at some point your cartridge(s) will really run out of toner and will need to be replaced. But if you can get another 50 to 500 pages out of your existing toner, you will have saved yourself some money on a replacement you didn’t need at the time the printer told you you needed it.

Some Googling found me this information on how to reset the toner on more recent Brother laser printers: http://www.amazon.com/gp/customer-reviews/R21X5O6QYB4IFQ/ref=cm_cr_arp_d_viewpnt
In case that URL ever goes missing, here’s this information copied from it on 20 March 2016:
- Get to the home screen. If you are stuck at the “Toner Low” or “Replace Toner” message, just press the red X.
- Press the FAX button on the touch screen (you may also need to press the Sending Faxes icon). This is ONLY to light up the numbers so you can LOCATE and only locate, don’t press, the * (asterisk) button. You know where it is now, somewhere to the right of the red X button. I put a sticky ‘sign here’ note tab to point to the *.
- Press the glowing Home button to get home.
- Open the top as if you were going to change the toner, but don’t remove any toner.
- With the top open, press and hold the now UNLIT * (asterisk) button for at least 5 seconds.
- Keep the lid open — the Toner Reset menu will show on the screen.
- Reset your ‘low’ or ’empty’ toner by pressing the color and type to reset, all with the lid open. (e.g. cstd or C.TNR.STD = cyan standard, cstr or C.TNR.STR = cyan starter, and one other for high yield [e.g. C.TNR.HC], etc. Just reset to whatever type you have installed. Note: C = cyan [blue], M = magenta [red], Y = yellow, and K= black)
- Close the lid and wait about 40 seconds per toner that was reset (i.e. 80 seconds if you reset two toners, 120 seconds if you reset three).
- Once the normal touchscreen controls are displayed again, the Toner Low message should be gone. Eventually you will have to replace toner, but you’ll be able to tell by the quality of the print.
NOTE: As at 20 March 2016, I have not tried these instructions, but next time I get a low toner message I will and will report back here.
Update 14 Jul 2016: I got my first toner low message for my three color toners, and have now reset as per the instructions above. So far, so good. Now to see how long before the toner REALLY runs out.
