Brother MFC 5840-CN Black Ink Not Dispensing

I know this is not the first time someone has posted with the problem of one of the colors not printing after replacing the cartridge.Mine happaens to be black and I have gone through the power flush mode at least eight times and still no luck getting black to print.Question is,can the individual jets be removed and cleaned/replaced individually?If so,anyone have instructions on how to do so?
Thanks,
billy3p

    I have the same problem with my black. I followed the same process, replaced the cartridge twice, and flushed and cleaned until I lost count. Still will not print. I love my printer but this is mind blowing.

I have been using the mehtod of loading an empty black cartridge with amonia that was mentioned in a previous post and have recovered some use of my black cartridge. I loaded and empy one with amonina water (half and half), ran several cleaning cycles, and then just left it in there for days. Every time I thought about it or passed by it I would run another cycle. Finally I put my black cartride back in and again ran several cycles and left it in. Again every time I thought about it or passed by it I would run another cycle. I finally started doing test prints and I'm now up to 3 1/2 lines back on my black and some blurred words, but its printing. Maybe after a few more I might get full use back. Give this method a try, especially if you've got nothing to loose. Good luck.

No, they cannot be cleaned once you lose the color completely. You'll need to replace the head.

Can my brothers printer work only on black ink (MFC 465 CN)


I am afraid you cannot print if (any) one of the cartridges is empty. Here is a screen capture from the properties of my MFC. At the bottom of the picture it says in French : Le MFC arrêtera l'impression Couleur/échelle de gris lorsqu'une ou plus des cartouches d'encre sera vide.

What it say in English is as follows: The MFC will stop printing in Color/Gray scale when one or more of the ink cartidges is empty.

Open the properties of the MFC. Under "Advanced" Tab Click the Printing Defaults at the bottom left. At the bottom of the window that pops up you will see the information that I translated for You.

Brother mfc 5840 won't print clearly


you need to check the maintainence kit and see if it's full. Also if it isn't, use some iso-proponal alcohol and some q-tips to clean the print section of the cartridge and the cartridge tray.

Black ink is not dispensing


There may be an air bubble in the black tubing, it will take several more cleaning cycles to clear. You can tell it to clean only the black and save the other inks.

Print head for brother mfc420cn


Cleaning the print head
To ensure good print quality, the MFC will regularly clean the print
head. You can start the cleaning process manually if needed.
Clean the print head and ink cartridges if you get a horizontal line in
the text or graphics on your printed pages. You can clean Black only
or three colors at a time (Cyan/Yellow/Magenta), or all four colors at
once.
Cleaning the print head consumes ink. Cleaning too often uses ink
unnecessarily.
Caution
Do NOT touch the print head. Touching the print head may cause
permanent damage and may void the print head’s warranty.
1 Press Ink.
2 Press ▲ or ▼ to select Cleaning.
Press Menu/Set.
3 Press ▲ or ▼ to select Black, Color or All.
Press Menu/Set.
The MFC will clean the print head. When cleaning is finished,
the MFC will go back to standby mode automatically.
If you clean the print head at least five times and the print has
not improved, call Brother Customer Service

Hope that helps,

Take Care,

Michael

Brother MFC 5840-CN - line appearing on copies


I have no idea whats happening here.. But it sounds a bit like when he prints from the pc, it uses a different paper stock? Could it be the paper from a direct copy is being used from a different source or tray? Or maybe it's like a 'draft' copy?

I know thats not much help, but if you want, I can spend some time investigatiing this.. But as over a hundred people have never bothered to reply to my posts, I'm a bit reluctant to waste time, unless it's appreciated.. Let me know if you really want to get involved at a deeper level..

Brother MFC 5840 Printing


That might be because of generic ink!
This generic ink destroys the nozzels due to a chemical reaction!

If you re lucky you will have good results when useing original brother ink carts.

Run the cleaning procedure twice after you have inserted the original carts!

Black Won't Print On MFC 420 CN


Use another new genuine (original brother) BK cart. Do the cleaning twice only for BK. Wait some time (4 hours). If the ink has dryed up, the cleaning ink will break up the dryed one. Do the cleaning again. If it doesnt work, please write again.
