My printer refuses to print in Black even if it is full but the color cartdridge Y and B are finished....How to make it print?


The way the Brother MFC-420CN is designed, it will not print at all if any of the ink tanks are empty. They say that this is to prevent damage to the printheads.

There is no workaround.

A lot of inkjet printers have this same restriction, if any tanks are empty, it will not print.

How to replace print heads on brother mfc


The printhead for this brother model is a service replacement, all the covers come off and the ink tubes and encoder strip. After replacement many settings have to be set in service mode, not a job you can do at home, plus the printhead costs nearly $100.00.

Brother MFC 420cn "Cannot Init"


This is the Head Error 41

Error 41 means there is a major problem with the printhead, usually
requires a print head replacement.

My advice is to take it to a
Brother service centre while if it is under warranty.

If it's out of warranty they are usually a throw away job, the heads cost as much as the printer.

Sorry I know what it feels like, just have a go and see what you can do, clean the heads and so on.

All the Best and good luck: Pineworks

MY mfc-290c does not print same colors as the photo in iphoto


Try printing the test print and see if all the colors are working, if some are missing you need to clean the printhead, and if you are using generic inks, sometimes the colors aren't as good as Brother inks.

Brother MFC-420CN All-In-One


unplug maqchine from power. take all carts out. wait 5 minutes. connect machine to power. insert carts as demanded. give the right answer if machine asks if the carts are changed. machine will do some cleaning.

do you use generic ink? in that case you might have clogged the printhead with wrong ink. The ph cant be cleaned anymore.

nevertheless try this (carts should be nearly full!):
press menue then start mono (blue copy) then fourtimes arrow up. machine will be in maintenance mode. press 7 then 6 then 4. Machine will display init_all. press start mono. machine will refill tubes and
ph with fresh ink and do some cleaning. after that press 7 then 6 then 3 and start mono. machine will do a powerpurge.
press zero then 9 to do a quality test print. If it cant do the job leave maintenance by pressing 9 then 9. do the test print manually by pressing ink etc.

If you still do not see any colors the ph is clogged and cant be fixed anymore. It has to be replaced.

Red and Yellow not Printing at all.


Did you use third party carts?

If yes, buy original brother ink carts and do the cleaning cycle again. If you are lucky the printhead isnt clogged due to the third party ink which has not the additives and glycerin needed for the printhead to run without probs.

 

In case the head is clogged there is nothing more what you can do. Sorry!  A replacement might costs more than a new mfc 440cn!

Mfc 420cn


Do use original brother ink to fix the problem: Do the cleaning twice (All colors and bk). You should see some blocks of the missing colors. If not printhead is damaged and cant be repaired (Dryed out or damaged valve or clogged with particles). If machine displays unable to clean, search googl for ERROR 46 (Reset and change of waist inktank)

Yellow will not print


Use a original brother ink cart. Do the cleaning twice. If you don't see any yellow blocks at all the printhead is crashed and can't be fixed anymore
