Stuts,

I guess you have used generic ink carts.

You should buy an original brother ink cart.

When done so make sure all other carts are at full level:
Press menu then start b/k copy then fourtimes arrow up (tel.index). Machine will be in maintenance mode. press 7 then 6 then 4 then start b/k copy. Machine will refresh ink within tubes and print head and do some power cleaning. when finished press 7 then 6 then 3 then start bk copy to run an extra power purge.
Leave maintenance by pressing 9 then 9.

Do run a quality test print.

If you re lucky the ph will work again.

THERE IS NO WAY TO CLEAN THE PH OUTSIDE EXCEPT BY Power Purge (7-6-3) within maintnenace mode.

If you like to save money refill ORIGINAL Carts by drilling a 2mm hole into the top (O of brother brandname) . You can leave the hole open to refill the cart next time directly without taking it out of the printer.

Mix some 3ml 85%-glycerin alc (drugstore) with 3ml of destilled water and 5 ml of DYE(!) ink and refill the c/y/m cart.

For bk mix 1 ml glycerin alc with 4ml dest. water and 15 ml bk DYE ink (shake well before refill).

This is -nearly- the exacte mixture of original brother ink.

My brother mfc j220 canoot print magenta color although on the display the magenta is full i clean many times but when i test print i didnt see dotted magenta. what can i do?


It looks like the magenta print head nozzels are blocked.
Inkjet printers need to be used frequently to prevent inkdrying out in the print head nozzles.
If the print head cleaning maintenance routine does not clear the blockages,then print head needs replacing, but it may be expensive.
It may be more cost effective to buy a later model and better printer thanreplace the print head.

it is very easy. Remove the print carts then on the left and right side of the ink holder is a small loop at the end of a wire. Move that to the side and pull it up. Do the same for the other side. Next pull out the print head that these two wires were holding in place.
-------- This will help. Thanks please keep updated.please do rate the solution positively .thank you for using fixya

How to improve print quality
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 (see Brother
numbers on page i).

I have a brother DCP-135c printer. the magenta ink not printing


The process to get to the print head will take you approx. 1 hour. Without being trained on it, there is a high failure rate upon completion.

The Scanner assembly needs to be taken off. Harness Cables for the Scanner need to be removed.The Upper Case Assembly needs to be taken off. Printhead casing and printhead tubing calbes need to be removed, printhead mainboard needs to be removed, and then you have access to the printhead.

Brother DCP-120C Printer - Does not print black, Black and magenta cartridges renewed with new Brother cartridges. Black ink level reset OK but not magenta. Have tried automatic head cleaning but still no...


have you recently had a paper jam. somtimes pieces of paper can become trapped under the print head which restricts the printing. if there is and its been there for a while the print head may need to be wiped/cleaned( a bit tricky) then a couple more print head cleans.

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.

There may be a release lever for the print head assembly which would allow you to remove the print head and clean the excess ink from it. If it appears to get better the more pages you print it may be just a matter of time and lots of pages before it cleans itself.
Try running the print head cleaning utility multiple times to help reduce the amount of ink on the print head. This could take quite a few times before it gets better.
