Black will not print

You'll have to run the cleaning mode a few times,
to do so you'll have to get into Maintenance Mode.

To do this:
Press MENU then * then 2 then 8 then 6 then 4
This takes some practice and you have to press them all within a few seconds.
If the machine doesn't say MAINTENANCE when you do it press STOP/EXIT and try again.

When in Maintenance Mode:
Press 7 then 6, then press 3, then press BLACK START
It will say Cleaning - this will take some time when it's done it will go back to MAINTENANCE

After it's completed try 0 then 9, this will print out a small Print Quality test page
it should have several rows of each color (Cyan, Magenta, Yellow and Black)
if they still don't look right then run the cleaning mode again and then print another quality page.

Continue to do this until the quality is back to normal,
when you're done to exit maintenance mode press 9 then 9 to return to normal operation.

note: this cleaning mode uses up a fair amount of ink, use sparingly

note: maintenance mode is for brother technicians and has some codes that can damage your machine, only use the codes I've explained in this solution


If this doesn't resolve your issue you may need a replacement print head,
this is an expensive fix if the machine is no longer under warranty.

You almost certainly have a defective printhead. When you make a color copy or print, the machine makes black by mixing your color inks.
If the machine is under warranty take it to an authorized service center (listed on Brother's web site) for free repair. If it's just barely past warranty, call Brother's Customer Support and plead for mercy. They often bend their rules to help a just-past-warranty customer.
If they won't cover it, steel yourself for bad news. The parts are expensive, and the required updates and adjustments are a time-consuming pain. You'll probably be told it costs more than a new machine. Good luck.

1st question that should be asked, is was it a genuine Brother approved cartridge with the right value of filtered ink?

If not then the jets will be possibly clogged.

if you return it for repair to brother under warranty, make sure its fitted with genuine cartridges otherwise warranty is void

please rate my help++++thanks for using fixya

Hello Acerilli

Sounds like the print head is either blocked or defective.
Try cleaning the print head first to see if this clears up the lack of black ink.

Press the "menu" button and then scroll down to the "ink" option and press OK
Now scroll down to "cleaning" and select OK.
Select "Black" and press OK then Black Start.

Repeat this process up to a maximum of 5 times.

If this does not clear it up, try a "purge".

Press "menu" "black start" "0 7 6" in sequence as quickly as possible (within 5 seconds)
All the lights should flash and you will see "cleaning_all" on the screen.
Now press 3 and Black start.

If this still does not work and there is no black, the print head is defective and needs to be replaced.
If you are under warranty, you can check here for a service center.

If there is no service center in your area and you are under warranty, call brother for an exchange.

If still under warranty, I would call Brother for an RMA (return merchandise authorization) code and return the product. Why fiddle with it?

Hey SHAWNY BOO,
The camera should be covered under a manufacturers warranty, and I would have it looked at by an authorized service technician. You could contact the manufacturer and they should have either a list of authorized service centers in your area, or they should send you a shipping label so you can ship it into an authorized service center. You could also bring it to a Geek Squad® precinct in a Best Buy™ store and they could send it out to an authorized service technician. I hope this helps!

Sincerely,
Allan

if you left your printer for two weeks or more without using, the print heads may be stuffiness. In this case (aparently yours cases) you must take your printer to a authorized service, they will can clean (with a proper fluid) or replace the ink heads, if cleaning is not possible.

I have the same problem. Found this solution on the Brother site:

If the faxes you receive and the copies you make print half blank pages
please follow the steps listed below:

1. Unplug the power cord

2. Lift the top cover up.

3. Next, lift the two purple release levers located on each side of the
metal plate. The print head will pop up.

4. Remove the ribbon cartridge from the unit.

5. Lift the plastic paper cover (located behind the black rubber
roller).

6. Carefully remove any paper that is jammed by pulling in an upward
direction.

7. Push the paper cover down (located behind the black rubber roller).

8. Place the ribbon cartridge back in the unit with the ribbed triangle
on the plastic casing furthest away from you. Make sure the cartridge
gears rest in the white gear holders.

9. Gently push down the print head until it clicks into place.

10. Close the top cover securely.

11. Plug the power cord back in.

Test by making a copy.

1. Place a document (with text on both sides) in the ADF (automatic
document feeder).

2. Adjust the paper guides on the sides of the ADF to fit the width of
the document.

3. Press the COPY key.
