Doc jam error usually means a jam in the adf (auto doc feed) when feeding a fax or doc to copy.

The most common reason brother mfc,s of this configuration have doc feed issues is believe it or not the hinge that operates the lid/adf, specifically the left side one (looking from the front). Inside the hinge there are two springs exerting tremendous force on the hinge (that enables the lid to stay up by itself) however this force eventually slowly breaks the fulcrum point of the hinge which leads to the lid not closing properly which means a sensor under the lid does not activate properly resulting in the adf stopping and resulting in the machine registering a jam. the difference between the sensor activating or not can be as little as a millimeter and is not often disernable. the hinge needs replacing by a techo.

the other reason could be you just have dirty adf feed rollers, clean them with a cotton rag dipped in metho, open the adf lid and give the rollers a scrub. the rollers should have 'tread' on them similar to a tyre, if not they are worn and need replacing.

One other possibility is there may be a paper fragment left over from a jam removal still caught in the paper path and activating a sensor activator that tells the machine paper is coming or going. most commonly in the section where the paper is looping on its return journey back out of the adf, open the adf lid, have a look with a torch and see how you go.

A few questions: - Did this problem just start? - Was there a paper jam and when the paper was dislodged the next few sheets were streaked? Running a few more pages usually clears this. - Is this a new toner cartridge? Did you just change the cartridge? Are you low on toner? Try removing the cartridge and gently rocking it back and forth, side to side. This will distribute the toner more evenly. - Is this a heavier weight paper then previously used? Try going back to the old weight and see if the problem continues.

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.

You can check if the paper guides are set properly by depressing the purple lever on the right front of the tray. The leading edge of the stack of paper should rise out of the tray. If the paper cannot rise, or rises unevenly, you need to adjust the guide on the tray. There should be between 1/16 and 1/18 of play from front to back for the stack of paper in the paper tray.
The loud click sounds alarming, but is not the problem.

-open front cover
-press 'Option' button
-then key *00 on the keypad
-close front cover

hope it helps
