    Hold down the menu key. While still holding the menu key, unplug the machine and plug it back in. Do not let go of the key until the machine reboots and the screen says "maintenence". Hit the following keys: 7, 6, 4,black start. The machine will then go into "power purge" or deep clean mode for about 5-7 minutes. When complete hit: 99 to get out of maintanence and reboot. Be sure to have extra ink cartidges on hand as it does use up a lot of ink but this process works the best every time when the printer wont print

Hi there,

You must have to do the cleaning process many times as necessary until it prints correctly.
Since the pipes still have magenta ink, it will have to drain all the magenta ink.

Press Ink Management, then select Cleaning Black. At the end print the quality test page.
Do the procedure until it prints correctly.

It will eventually clear itself !

Most of the Brother MFCs use ink Tanks NOT ink cartridges, as the MFCs have a separte print head - ink cartridges include a print head which get thrown out with the rest of the cartridge when replaced. This is why Brother ink replacements are so cheap compared to "normal" inkjet printers.
It may seem like it's taking a long time, but there is quite a lot of ink in the pipes from the ink tanks to the print head.

I have a Brother MFC-6490. The printer can not print in black. The black cartridge is new. There is no problem with color printing. Thanks for your help.

Hi

Remove the black ink cartrige and rub the print head into a plain paper with rubbing alcohol until ink flows. If not rubbing alcohol, no problem. Just rub the printhead into a plain paper.

Then try to print again. I hope it helps you. Please post comments if you need more help. Regards

Mfc 5860 red printing green - already checked print levels. all are fine.

1. Confirm that the colors are incorrect by printing a Print Quality Check Sheet

a. Press INK.

b. Press the UP OR DOWN ARROW key to select Test Print.

c. Press OK.

d. Use the UP OR DOWN ARROW key to select Print Quality.

e. Press OK.

f. Press COLOR START

The machine will generate the Print Quality Check Sheet.

2. The LCD will ask "IS QUALITY OK? 1. YES 2. NO"

a. Press STOP/EXIT to return to the "Date and Time" display.

3. Evaluate the Print Quality Check Sheet.

On the Print Quality Check Sheet each of the four colors is represented by a slanted square pattern made up of 96 individual blocks. The colors should appear in the following order from left to right: Black - Yellow - Cyan - Magenta.

NOTE: Cyan is the light blue color and magenta is the pinkish color.

a. If the colors on the Print Quality Check Sheet do not match the sequence listed above then the ink cartridges are most likely installed in the wrong order. Continue to STEP 4 to resolve this.

4. Open the Ink Refill cover.

5. Open the cartridge covers of the colors that do not appear in the correct order.

6. Remove the cartridges and reinstall them in the correct slots. On Brother Genuine Cartridges the color of the label will match the color of the cartridge cover.

7. Run a "Setup Purge". A Setup Purge is necessary to replace the ink in the ink supply tubes with the correct color. One or more of the ink cartridges may run empty during this process. If they do, replace the empty cartridge with a Brother Genuine Ink Cartridge before continuing the process.

c. Press 6, the LCD will display eINIT__P ALL

d. Press the RIGHT ARROW key until one of the colors that was installed incorrectly is displayed. i.e. eINIT__P CYAN.

e. Press the BLACK START Key.

  • After the machine completes the Setup Purge it will return to the Standby Display.

8. Print another Print Quality Check Sheet

a. Press INK.

b. Press the UP OR DOWN ARROW key to select Test Print.

c. Press OK.

d. Use the UP OR DOWN ARROW key to select Print Quality.

e. Press OK.

f. Press COLOR START

9. The machine will generate another Print Quality Check Sheet.

a. If all four colors printed correctly the issue is resolved.

Brother mfc-410cn colour cartridge problem

There may be three problems here.

1.Not doubting your skills for one minute, nor wishing to offend you in any way, but did you remove the protection strip off of the Magenta ink cartridge? Sometimes we forget to do that.

2.Once a new ink catridge is installed, it's best to go to the Brother diagnostic tools section, and run a test. Sometimes an error code is kept, (Ink cartridge is empty), and the diagnostic tool checks this out. It then clears the error code, and 'recognizes' the new ink cartridge.

3.Ink may have dried, for the tiny little holes for the magenta ink cartridge, where it attaches to the body of the printer. Just this one ink cartridge. Suggest you don a pair of rubber dishwashing gloves. MFC-410cn -> Unplugged <- from the surge protector, use a clean, lint free, warm water, damp cloth, and wipe the holes for the ink cartridge, where it lines up with the printer body. This will be where you see that copper metal strip. (Or perhaps it's brass)

To clarify, you are cleaning the printer body. The area where the ink cartridge goes, and the metal strip. The ink passes from the ink cartridge, and goes through holes in the body of the printer. The metal strip is where these holes are located. Allow this area to dry. You may want to use a hair dryer set on low heat to speed the drying process up. Constantly move the hair dryer back and forth. Keep it about a finger length away.

Once you are satisfied this are is dry, reinsert the magenta ink cartridge. Plug the printer back into power. Advise waiting one minute, then turn the printer on.
Use the Brother diagnostic tool.

Should you not be able to find the Brother diagnostic tool, I suggest you go to Start>Hover your mouse cursor on All Programs>Go over to Brother>MFC-410cn>and to the Help section. The Help section, will tell you how to open the diagnostic tool.

Brother mfc MFC-5440CN magenta issues

If you have used generic ink the head is clogged and cant be cleaned anymore.

Last chance is to use original brother ink which has cleaning fluids within the ink. Run the cleaning procedure twice and simply print 10 PAGES afterwards. Wait A DAY AND TRY TO PRINT IN MAG AGAIN:

If there will be no mag. the ph is definitley clogged and needs replacement.

First, wouldn't print black, now won't print magenta- all new cartridges!

Unplug machinepowercord. Open printer and take all carts out. Plug in power. Machine demands carts. Put new one in: Replace with original ink carts!. When asked push 1 (yes New cart). If you have used thirdparty carts, there could be a prob due to construticon or ink quality. In case there is no bk after 3x cleaning cycles anymore, the head is clogged: This happens because the filter in front of the nozzels is clogged by pigmented ink. DO USE ONLY DYE INK for all types of brother inkjet machines!!!
