Question about Brother MFC-5840CN All-In-One InkJet Printer

Open Question

About a year ago I lost the ability to print magenta on my Brother MFC5840CN. I found a code to use for a power cleaning and it resolved the problem...does this sound feasible and if so, do you know the procedure.

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.

If you don't print at least once a month, you will clog the machine. You unfortunately have to get it fixed by a professional or get a new printer. Sorry!

Open up amd release blue stay at bottom by pressing edges inward and pulling slightly forward. Remove the 4 screws, 2 small plastic covers and the earth screw. Pull out the ribbon connector near the USB plug. Unplug the 2 white and one red connectors, noting how the cables fit in. Fully open the lid and pop the scanner part off. Remove all the ink cartridges. Now using a flat screwdriver unclip the top of the base all the way round and lift off. The print head is now accessible. Rotate the white paper feed cogs to release the print head. Slide it all the way to the right and remove it by tilting the back edge upwards. You mow have access to the print head!!!!

Looking online Magenta printhead often seems to be the problem. I notice that my magena cartridge has split open and is leaking. are they connected? Any thoughts on how I repair it

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.

I have a problem with print quality of my Brother printer mFC-6490CW, I have run the ink management utility, the black, yellow and magenta printed to about 95% just one dotted line missing on the black,...


Well, this is a common problem with people who purchase Brother printers, but do not always use Brother Ink Cartridges. Brother has a cleaning agent in the print cartridge and the compatibles do not.

"If you have a lack of one (or more) color do the following:

Make sure all carts are full, placed well and are secured. Insert a new ORIGINAL BROTHER CART for the one that shows no color.

Press menu then start bk-copy then four times arrow up quick after another. machine will switch into maintenance mode and all lights will flash. Press 7 then 6 then 4 then start bk-copy. machine will initialize the carts and refresh ink within tubes and print head. After that it does some power cleaning. When finished press 7 then 6 then 3 then start bk-copy. machine will run a power purge. when finished press 9 then 9 to leave the maintenance mode. do run a quality test print.

This should clean the lines out and clear up your issue.

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.

Yes, another suggestion is to give it back to the dealer or a service partner which can be found on the homepage of brother. If the printer is 3 months old you are in guarantee time. Its a common problem with the printheads that one color (M or Y) is lost somehow sometime...! (Valveproblem within the printhead) You cant fix it yourself (May need a new printhead).

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!!!

My printer doesint print magenta on test page


Did you use third party ink? Insert a genuine (original) brother ink cart and do the cleaning twice. there should be magenta again. If there is no magenta after that, this could be either because of air in the system (thats why you should do the cleaning twice!) or the nozzels are clogged (and cant be cleaned anymore).
