Have you tried to re-start the printer /1st unplug and re-start again this might help but leave unpluged for 60 seconds.

Black ink on my Brother MFC-420CN is faint and streaky

You said you replaced the cartridges. Were they Genuine Brothers' Cartridges?

My Brother MFC-240C, does not like Generic Printer Cartridges. That sounds like your problem. Also I had with Brother's was problem with Color. Color that should be Yellow, will turn out Green, or Blue Green, etc. The Generic Cartridges, also printed lines thru the words. That's what the Companies do., so they can keep selling the ink cartridges.

Some Printers, are able to use Generic, but you have to fill them up yourself and I heard, quite MESSY, or Take them to have them filled.

So I learned, thru trial and error, that you must use the ORIGINAL Genuine Cartridges for the PRINTERS.

This is the only advice I can give you. If you find this helpful, pls rate me.

Thanks and Good Luck :0)

My brother mfc 420cn printer quit printing...

I'd venture to say that if you haven't used it in a while the ink dried up and clogged the print head. It is probably a job for a service center. Good luck

When i run a test pattern on my mfc 420 it will not print the yel

Clean the yellow printer head with the self cleaning function. Try printing yellow from a computer, etc. Check ink level, make sure it is not telling you low ink.

Want to print with black ink only using Brother MFC-420CN

I see it's been a while since you posted your question but in case anyone else is wondering about this, I'll answer.  The information is not in the User's Guide booklet but in the Software User's Guide which should be available on your software disk, or you can view it here 

Basically, you go to the advanced tab under the printing preferences and select grayscale.

MFC-420CN does not print black

My yellow cartridge was doing the same thing as your black. So I took the cartridge out, and took a flashlight to see how it works. There is like a little straw on the right hand side which goes up into the printer cartridge, this I assume is to measure the ink. I took a needle and cleaned that 'straw' thoroughly. Reseated the ink, ran cleaning and test print, and then the printer found the yellow ink! You could give that a try. It might work for you too. (I have never used any ink but Brother ink in the printer, btw.)

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.
