Re: Toner Error

It's possible that the toner has not been reset due to the fact that you changed the drum at the same time. There is a cover on the left hand side of the toner covering some gears. Remove this (one screw) and wind the toner reset gear (white one by memory) back and refit the cover and put the toner back in the machine. It may take you a few to get it in the right spot but that will reset your toner count and get rid of the error.

Re: Toner Error

You guys were right about the plastic peace! after taking off the outside panel and locating the plastic piece I discovered it had a broker piece in it! I then removed the circut board and discovered that there is a plastic piece on the lower right side on the back of the circut board. Anyway The Final solution here is to fill that small part on the back of the circut board with plastic or paper folded up enough to seperate the legs on the back piece and block them from seeing each other.
I think it is a infared sensor that is the ultimate problem...Any way it worked for me. and I thank you all for pointing me in the right direction++++++++

Re: Toner Error

Bowdo is exactly right. I just had this problem this morning and the solution is a crappy little spring attached to a black piece of plastic on the inside left of where you install the toner/drum.

The solution is easy and takes about 5 mins, but does require a screwdriver. Why Brother wont walk you through this on the phone I have no clue. Actually, I suspect the spring mechanism is only there to prevent use of non-brother toner and drums since thats where they make their money... but another matter entirely.

To fix it, you need to take off the left hand gray plastic exterior cover. It is a little hard to find the two screws that hold it on. One is behind the flip down cover on the back and the other is behind the pull down gray plastic corner shaped cover on the front (with the button) that you use to load the toner/drum.

Unscrew the screws and pull off the left hand cover. If you also take out the drum/toner cartridge you can touch the spring with black plastic on the inside left and simultaneously see it rotate from the outside left. The spring is actually a piece of wire that snaps the black plastic back (very poorly). The purpose of the spring/plastic part is to engage something that looks like a green circuit board on the outside left (you can only see if the left cover is off). I have had two problems with this spring. One it can come off entirely which requires some tweezers to reattach it correctly. Two it can fail to rotate all the way so that engages the green circuit board. Just rotate it all the way until it "fills a gap" in the circuit. You cant test it by putting the drum/cartridge back in. Thats when the error went away for me.

Basically I think this is a great machine with really, really, really crappy part that causes all kinds of problems. In fact, seems like there ought to be a workaround so that you can disable the spring and have the circuit contacted all the time. Again, I think this is purposely done (poorly and after the intital design) to make people use Brother cartridges.

Hopefully this helps. I am not a tech wizard and I fixed it myself without really knowing what was wrong, so dont waste money on their "authorized repair." Just do it yourself and get back up an running.

Re: Toner Error

Somebody tried to install the toner without the drum and pushed the same black plastic flipper arm off its shaft. I pushed it back on from the outside.

Hi there,

Below are instructions that I have found from the internet. Hope that they will help.

  • Open the front cover of the printer.
  • Hold down the Go button for 4 seconds until all the LEDs light up. Then release the Go button
  • Remove the drum unit and toner cartridge assembly.
  • Replace the drum unit and toner cartridge assembly back into the printer.
  • Close the front cover of the printer
  • Your drum unit should now be reset

    1.Remove the drum unit and toner cartridge. Wait 1 or 2 minutes.
    2.Replace the drum unit and toner cartridge into printer.
    3.The error message "Change Drum Soon/Drum end soon" will continue to appear if the drum counter was not reset when you replace the drum unit.
    4.To clear this error message, you need to reset the drum counter as instructed below.
    5.Make sure that the machine is turned on.

    For MFC users: To confirm you are installing a new drum, press 1. For DCP users To confirm you are installing a new drum, press the Up Arrow key

    7.When the LCD shows Accepted, close the front cover.
    8.Your drum is now reset.

    Resetting the drum unit will not improve print quality. It only resets your drum and allows you to continue to print. You decide when to replace the drum unit not the manufacturer!

Error message "put the black toner cartridge back in"

I got this same error message on a newly acquired Brother DCP-7040 that I purchased used off of ebay.

As I was troubleshooting this unit (that I bought untested off of ebay - hey gambling has paid off handsomely for me many times before!), this error message kept popping up.

I checked the COUNTERS (page & Drum life) and found out that the DRUM had 0% life left. BUT, the reason it showed ZERO was because this unit did not have any drum! The toner cartridge (TN-360) needs to sit WITHIN the drum (DR-360) on this DCP-7040 unit, as well as in models DCP-7030, MFC-7340, MFC-7345C, and MFC-7440N.

So perhaps some of these "put the black toner cartridge back in" problems could be related to the DRUM (or lack thereof). A possible tipoff (since the toner cartridge actually does slide into the unit much like other units that do not use Brother's DRUM carrier) seems to be the relative ease with which the toner cartridge slides into the DCP-7040 and really doesn't seem to "lock" into position real firmly.

Model MFC 8480 DN is giving a drum error message. HELP! Is there an online users manual available?

Yes, the manual is available from Brother. See and then look at the results for all of the manuals. The direct link to the User's Guide is .

A drum error could mean that the corona wire on the drum needs cleaning or that the drum unit needs to be replaced. Make sure that the unit has cooled down before doing any maintanence on the drum unit. To clean the corona wire, turn off the machine and unplug all of the cables from the printer (telephone cord first, power last). Then open the front cover and pull out the drum and toner unit. Move the blue tab back and forth (right to left and left to right) several times. Leave the tab in the home position (aligning the triangle on the tab with that on the unit) when done. Then reinstall the drum and toner unit. Close the cover and reconnect the cables before turning the unit back on.

If you need to replace the drum unit, order DR-20. For changing the drum follow the above steps through removing the drum and toner unit. Then remove the toner from the drum (make sure not to spill the toner) by pushing down on the blue lever. Then put the toner cartridge into the new drum (the blue lever should lift into place and you should hear the cartridge snap into place). To reset the drum counter, do not close the front cover. Leave it open then connect the cables and turn on the unit. Press Clear/Back and then press 1. Close the cover when you see Accepted.

I hope this helps.

I have a Brother HL-2142 Compact High quality mono laser printer and I am having trouble putting the new toner cartridge back in as it flashes error and the paper gets jammed. I dont know where the...

Open the front door and pull the whole toner and drum unit out of printer. The toner locking lever is usually on the left hand side as you see it and is usually blue in colour. It needs compressing and at the same time lift the front of the toner cartridge out of the drum unit. Your new cartridge will simply lock into place. When you install the complete unit and close the door, the new toner cartridge will reset your printers counter.

Brother 8460n - toner error

Hi, This worked for us:

The message "Toner Error" is usually caused by the drum and/or toner
cartridge not being installed properly or if the machine does not
recognize the toner. To clear this message, follow the steps listed

1. Verify you are using Genuine Brother Cartridges. Brother strongly
recommends that you do not refill the toner cartridges provided with
your machine. We also strongly recommend that you continue to use only
Genuine Brother Brand replacement toner cartridges. Use or attempted use
of potentially incompatible tone cartridges in the Brother machine may cause damage to the machine and/or may result in
unsatisfactory print quality. Our warranty coverage does not apply to
any problem that is caused by the use of unauthorized third party toner
and/or cartridges. To protect your investment and obtain premium
performance from the Brother machine, we strongly recommend the use of
Genuine Brother Supplies.

2. Make sure that you are using the correct drum and toner cartridge(s)
for your machine. The part numbers for your model are as follows:
NOTE: Some cartridges can look EXACTLY the same among different models
and will fit the machine even if they are not designed for use in that
model. Verify the part number before using the cartridge(s).

TN550: Toner cartridge (standard)
TN580: Toner cartridge (high yield)
DR520 = Drum unitt.

3. Make sure that the cartridge is not damaged. Remove the toner
cartridge by following the steps listed below:

a. Press the cover release button and then open the front cover.

b. Remove the old drum unit and toner cartridge assembly. Place it on a
drop cloth or disposable paper to avoid scattering toner.
NOTE: Be careful not to spill the toner. If toner gets on your
clothes or hands, wipe or wash it off immediately with cold water.

c. Hold down the blue lock lever on the right and pull the toner
cartridge out of the drum unit.

d. Look at the toner cartridge and see if any parts or pieces appear to
be broken or missing, if so, the cartridge may be defective and should
be replaced.

4. If the toner cartridge is not damaged, reinstall it into the drum
unit. If it was damaged, use a new toner cartridge and reinstall it into
the drum unit.

5. Reset the drum/toner unit into the machine.

6. Close the front cover.

7. If the message "Toner Error' continues to appear on the display
unplug the machine from the wall outlet.

8. Open the front cover and remove the drum and toner assembly.

9. Look inside where the drum was. On the left side wall, look for a
small, black plastic lever/actuator. A flashlight may help see it.

10. Using the palm of your hand, slide it along the left wall in and
out a few times as this may free up the actuator/lever in case it is
stuck. The actuator/lever is spring loaded and needs to move back and
spring forward to operate correctly.

If the lever does not move, spring back or is missing and your machine
is within warranty, you can locate a Brother Authorized Service Center
(ASC) in your area or contact Brother Customer Service by calling
1-877-Brother (1-877-276-8437) Monday through Friday, excluding
holidays. If the machine is out of warranty, you can locate a Brother
Authorized Service Center using the information listed above.

If the lever moves freely and springs back to its original position
continue to Step 11.

11. Reinstall the drum and toner assembly, close the front cover and
plug the machine in.

HELP! Brother MFC-8460 "Toner Life End" won't clear

The problem with a new toner cartridge that will not signal the printer that it has been changed has to do with a gear positioned wrong on the new or rebuilt cartridge... we had 3 factory brand new toners that would not clear the replace the toner message... I finally found the following link that came from a toner company that sells refills that tells how to reposition the gear to let the machine know a new cartridge has been installed. I did the proceedure on pages 5 & 6 having to reposition the gear and all cartidges then worked flawless... it works.
