I have found that the latch on the left side that swings down and up with the door opening and closing comes off or unhooked. Make sure it is pulled down. Then it will allow the cartridge and drum to come free. Hope this helps.

Do not reset the drum counter when you only replace the toner cartridge

3.Take out the drum unit and toner cartridge assembly.


  • We recommend that you put the drum unit and toner cartridge assembly on a piece of disposable paper or cloth in case you accidentally spill or scatter toner.
  • To prevent damage to the printer from static electricity, DO NOT touch the electrodes shown in the illustration.

4.Push down the blue lock lever and take the toner cartridge out of the drum unit.


  • DO NOT put a toner cartridge into a fire. It could explode, resulting in injuries.
  • Use neutral detergents when cleaning the printer.
  • DO NOT use cleaning materials that contain ammonia, alcohol, any type of spray, or any type of flammable
    substance to clean the outside or inside of the machine. Doing this may cause a fire or electrical shock.
  • Be careful not to inhale toner.
  • Handle the toner cartridge carefully. If toner scatters on your hands or clothes, wipe or wash it off with cold water at once.
  • To avoid print quality problems, DO NOT touch the shaded parts shown in the illustrations.
5.Unpack the new drum unit

How do i change the toner on m my HL 2040 brother printer


How to Change a Toner Cart in a Brother HL 2040

The Brother HL 2040 laser printer has a toner cartridge that supplies toner to the drum assembly so that the printer can print properly. When the LED on the front of the printer indicates you are low on toner, you will need to replace the toner cartridge to maintain good print quality. Fortunately, the toner cartridge can be replaced without any special tools.

Instructions
Things You'll Need:

* Replacement toner cartridge (part number TN350 or TN360)
* Paper towel or scrap paper



Grasp the front cover of the printer and pull it toward you to open the toner door. Reach into the printer and grab the combined toner cartridge/drum assembly. Lift up slightly and pull it out of the front of the printer.

Place the cartridge and drum on a paper towel, spare sheet of paper, rag or other surface that can get dirty. Loose toner particles may spill from the cartridge.

Press the blue locking lever on the cartridge/drum unit to unlock the toner cartridge from the drum. Lift the toner cartridge up and away from the drum unit. Dispose of the old toner cartridge in accordance with your local regulations. Seal it in a plastic bag to keep loose toner from spilling.

Brother MFC-7420 just started printing a shadow image


Sounds like a bad drum cartridge. Pull the toner/drum cartridge out of the machine and set it down. Press down on a (blue?) tab to release the toner cartridge, and you can lift the toner cartridge out of the drum cartridge. There is a cleaning blade in there - a soft plastic blade that rides against the drum and scrapes off toner that didn't get transferred to the paper. If it gets stuck off the drum surface, images repeat a few inches (one drum circumference) down the page.

A new DR-350 drum unit should fix it. have the machine's power on when replacing it. While the door is open, touch the CLEAR key. The display will read "REPLACE DRUM?" or something like that. Press 1 for Yes.

A piece of a label is stuck somewhere on the roller and is making a copy of the label on everything I'm printing.


i believe your label is stuck on the drum, inside the toner cartridge. Most, likely you will need to replace the toner cartridge. Take the toner cartridge out, flip it upside swing the door to the side and look at the drum and see if you see it. you might need to rotate the drum using the gears to advance the roller. If you do find it, you can try to pull it off, but regardless, it will probably damage the cartridge, but its worth a try.

if the label is not there, the only other possibility is on the fuser, which will need to get replaced.

hope that helps

The problem is the drum unit & toner catridge the paper stock inside the drum unit & toner catridge..


I understand the paper is stuck inside the drum unit and toner cartridge. Great. Take the drum unit out, separate the toner cartridge, and since you see paper, pull it out carefully with the tweezers. Do not touch the drum or the toner cartridge part.

The toner tray will not pull out from the machine


Replacing the Toner Cartridge
The MFC can print up to 6,000 pages using a high yield toner cartridge. When
the toner cartridge is running low, the LCD shows TONER LOW. The MFC is
supplied with a standard toner cartridge that must be replaced after
approximately 3,000 pages. Actual page count will vary depending on your
average document type (i.e., standard letter, detailed graphics).
Discard the used toner cartridge according to local regulations. If you are not
sure of them, your local Sanitation Department. Be sure to seal the toner
cartridge tightly so toner powder does not spill out of the cartridge. When
discarding used toner cartridges, keep them separate from domestic garbage.
We recommend that you clean the MFC when you replace the toner cartridge.
1 Open the front cover and pull out the drum unit.
Place the drum unit on a drop cloth or large piece of disposable paper to avoid
spilling and scattering the toner.
2 Hold down the lock lever on the right and pull the toner cartridge out of the drum
unit assembly.
Caution
Handle the toner cartridge carefully. If toner scatters on your hands or clothes,
immediately wipe it off or wash it with cold water.
3 Unpack the new toner cartridge. Place the used toner cartridge into the
aluminum bag and discard it according to local regulations.
 Wait to unpack the toner cartridge until immediately before you install it in the
MFC. If a toner cartridge is left unpacked for a long period of time, the toner life
is shortened.
 You can use only a genuine Brother toner cartridge (TN-430 or TN-460), which
is specially formulated to ensure top print quality. Using another brand of toner
cartridge may void your MFC’s warranty. Warranty coverage does not apply to
problems caused by the use of 3rd party Toner, 3rd party Toner Cartridge or 3rd
party Drum unit.
4 Gently rock the toner cartidge from side
to side five or six times to distribute the
toner evenly inside the cartridge.
5 Remove the protective cover.
6 Insert the new toner cartridge in the
drum unit until it clicks into place.
7 Clean the primary corona
wire inside the drum unit by
gently sliding the blue tab
from right to left several
times. Return the blue tab to
the Home position ( )
before reinstalling the drum
unit assembly.
Reinstall the drum unit and close the
front cover.
Replacing the Drum Unit
The MFC uses a drum unit to create print images on paper. If the LCD shows
CHANGE DRUM SOON, the drum unit is near the end of its life and it is time
to purchase a new one.
Even if the LCD shows CHANGE DRUM SOON, you may be able to continue
printing without having to replace the drum unit for a while. However, if there
is a noticeable deterioration in the output print quality (even before CHANGE
DRUM SOON appears), then the drum unit should be replaced. You should
clean the MFC when you replace the drum unit. (See page 21-18.)
Caution
When removing the drum unit, handle it carefully because it contains toner. If
toner scatters and your hands or clothes get dirty, immediately wipe or wash
with cold water.
WARNING
Just after you have used the MFC, some
internal parts of the MFC are extremely
HOT! So please be careful.
The drum unit is a consumable item, and it is necessary to replace it periodically.
There are many factors that determine the actual drum life, such as temperature,
humidity, type of paper and how much toner you use for the number of pages per print
job. The estimated drum life is up to 20,000 pages. The actual number of pages your
drum will print may be significantly less than these estimates. Because we have no
control over the many factors that determine the actual drum life, we cannot
guarantee a minimum number of pages that will be printed by your drum.

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
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.
