Toner Error - reinstall drum unit

I don't know whether the drum unit is bad or not. We have replaced the drum and still get the same error message. Our building was struck by lightning, and I'm wondering it that is causing the problem. Is there any way of checking the printer computer hardware to check for problems there, or in the drum unit sensors?

    I replaced the toner cartridge and got this error. I reinstalled the old cartridge and I still get this error. I tried the solution offered but it did not work for me.

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
below:

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.

I HAVE REPLACED TONER WITH THE CORRECT BROTHER TONER CARRTRIDGE AND THE MACHINE KEEPS TELLING ME TONER ERROR AND REINSTALL DRUM UNIT..HELP


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
  • MFC / DCP PRINTER SERIES

    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.

Error message after installing new tonner


Check the little switch/door on the left hand side of the drums.
This has worked successfully for me.

Symptom:
After replacement of a C3530 Image Drum, the message, "Toner Sensor Error" is displayed.

0.10a?openelement&fieldelemformat=gif




Cause:
The plastic shutter in the ID is fully or partially covering the toner sensor window.




Resolution:
Move the cover upward to allow for the sensor to become fully exposed prior to reinstalling the drum.

Toner sensor error after replacing cartrige...


Hopefully this will clear up a little confusion I had:

1. Follow instructions for replacing toner cartridge.
2. Remove drum from printer. Take care not to handle the drum surface. Look for a small rectangular window or depression. The window will be completely or partially blocked by a flap.
3. Use a fine pointed instrument to move the flap up, so that the sensor underneath is visible.
4. Replace the drum. The error should clear after the print engine has reset.

Toner/drum problems


This seems to happen some of the time. Brother has an FAQ for this:

1. Verify the toner cartridge is installed correctly by following the
steps listed below:

a. Open the front cover.

b. Lift the drum unit slightly and pull it out. Place the drum unit on
adrop cloth or large piece of disposable paper to avoid spilling and
scattering the toner.

c. Remove the toner cartridge from the drum by holding down the lock
lever (blue tab) on the left side of the drum unit and lift the toner
out.
*Handle the toner cartridge carefully. If toner scatters on your hands
or clothes, immediately wash it off with cold water.

d. Gently rock the toner cartridge from side to side five or six times
to distribute the toner evenly inside the cartridge.

e. Place the toner cartridge into the drum (be sure it clicks into
place).

f. Clean the primary corona wire inside the drum unit by gently sliding
the blue tab on the top of the cartridge from right to left several
times. Return the blue tab to the home position before reinstalling the
drum unit assembly.

g. Reseat the drum unit into the machine.

h. Close the front cover.

2. If the message "Toner Life End" continues to appear on the display,
contact Brother Customer Service at 1-877-Brother (276-8437) Monday
through Friday, 9:00am - 7:00pm EST, excluding holidays.
