Question about Brother MFC 420CN All-In-One InkJet Printer

1 Answer

Brother MFC-420cn AIO, black does not print

Changed all the cartridges but black doesn't print.

I did the cleaning mode, tried alcohol in an old cartridges, ran 100's of pages of black print to see if it would start printing. Had to cover the sensor, started saying no ink with a new one.

I not going to take the machine part unless it's a simple fix (I repair Medical equipment so I can perform some fixes). I'm tired of messing with this and very close to just getting a new printer. The off market ink was very affordable but don't know if this is what caused my problem.

Which printer do you recommend to replace this printer (if there's not other suggestion for a fix) with affordable ink or refillable ink?. Looking for an all-in-one (but don't really need fax, rarely used) maybe with wireless or networking. We never did got the networking to work with our router so the next setup I'd like to have all computers be able to print.

Thanks in advance for your time.

    I reinstalled the cd software as instructed by black still did not work. Can you guys recommend a decent printer without expensive ink?

    The black ink cartridge is full.

    When I print, only the colors in the document print, but the black is left blank.



    For example: I print out a Text document, the printer goes through the motion of printing.... but nothing is being printed onto the page.

Normal 0 Driver could be corrupt.
Disconnect the printer or at least be sure it is turned off. I'd do both and reinstall the CD software program that came withthe printer. When the software program asks you to connect theprinter to the USB port, do so and it should again work properly.
Hope this helps. Bud

Hi my printer won't print black, test colour work but no black, therefore all text to print is blank. I have replaced the ink with a new one and cleaned it 5 times, still no black ink. Thanks


Hi

Clean it manually by removing the black ink cartridge and rub the print head into a paper with rubbing alcohol until ink flows more. Then run the print nozzle to clean the print head thoroughly. After, try to print again.

If not, dip the print head only into hot water for 5 minutes and then run the print nozzle.

Let me know if you need more help

The print head is clogged.Try powerful cleaning:
Press menu, then start black copy, then four times arrow-up quickly after another.Machine will be in maintenance mode
(all lights will flash).
Press 7-6-4 and OK (or start-black-copy).
When finished press 7-6-3 then start black copy,
printer will do a power purge.
Leave maintenance mode by pressing 9-9.
If this not help better think about new printer, because cost of repairing this one is profitable.

Changed all 4 cartridges, yellow, red, grey not printing. Only blue & black print


Sounds like most of the color lines (the "cables" between print head and cartridges) either have clogged ink in them, or air bubbles. Try the cleaning process found by pressing Ink Management and then Menu/Set twice. After the test print sheet is printed, answer the question(s) in the display and print up to five test prints by answering the questions. 
It should solve the problem, but if it doesn't, you should perform a heavier duty purge found in the service mode.

Remove the black cartridge again and remove the plastic tape where the ink comes out and then re-insert and try again.

Black cartridge doesn't print


you need to do a hard reset on the printer as well it might clear up the problem and recognize the ink at its proper levels.

refer to your user manual or let us know and we will find the procedure to do so.

i have a similar model and know how picky they can be.

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.

Won't print Color


Have you check on your printer's color preference? It may only be a simple problem with your gray scale.Change the color preference on your printer icon's menu. You can also clean up your electronic connectors that comes in contact with the cartridges with a cotton dipped in alcohol. See <a href="http://www.printerquickfix.blogspot.com/">troubleshooting</a> procedures here.

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.
